Description: The present invention relates to a support for a drafting arrangement of a textile machine according to the preamble of claim 1 and a method for producing a support according to the preamble of claim 6. A support for a carrier of a drafting arrangement is known from DE 39 02 859 Al and is produced by assembling two plates together, which are dimensioned accordingly for the loads occurring on the drafting arrangement. In this case, the two identically formed plates arranged parallel to one another are connected to one another by spacers. Furthermore, a support configured in one piece with a U-shaped contour is known, which is produced from an end face and side walls which extend perpendicularly to the end face and parallel to one another. The support is produced by the use of a deep-drawing tool. The side walls are connected to one another on their side remote from the end face by spacers. This serves to stabilise the support, which is open on the side remote from the end face. The outlay for stabilising the support, which occurs owing to the increased material assembly outlay and the use of expensive deep-drawing tools has proven disadvantageous in the above-mentioned prior art. The invention is based on the object of providing a support for a carrier of a drafting arrangement, which is simple and economical to produce and can be implemented in a tool-reducing manner. This is achieved, according to the invention, with respect to the support by the characterising features of claim 1 and with respect to the method by the characterising features of claim 6. Further advantageous configurations are the subject of the sub-claims. According to claim 1, it is proposed that the support, for stabilisation perpendicularly to the end face and the side walls has angled sections, which are connected to one another positively and in that the spatial form of the support is produced by bending. The support is stabilised by the sections which are positively connected to one another and extend at least section-wise over the length of the side walls, without the use of spacers or the like being necessary, as is the case in the prior art. The torques transmitted during operation of the drafting arrangement via the carrier onto the support can be better absorbed owing to the higher torsional rigidity of the support. Owing to the one-piece design of the support, the construction is simplified. In addition, the support according to the invention can be produced more economically as the use of expensive deep-drawing tools, which are subject to heavy wear in the production of a support according to the prior art, or the use of spacers or the like, is not necessary for stabilisation. In particular, some of the sections which can be positively joined in to one another have a smaller overdimension. The connection of the sections can therefore take place by means of a press fit, so the use of additional connecting means, such as screws or rivets, or the use of other connecting methods, such as welding or soldering, can be dispensed with. This contributes to a reduction in the working steps required for production, so production of the support becomes more economical. In particular, suitable shaping of the sections positively joined to one another combined with the press fit, can achieve a frictional-positive connection of the side walls, which prevents the side walls being displaced relative to one another because of a force directed perpendicularly to them. Furthermore, a through-hole to receive an adjusting means for height-adjustability of the carrier may be arranged on the upper side configured by the angled sections. The adjusting means can be configured as a screw, which is supported on the upper side of the support. Furthermore, at least one overturn can be provided on one of the sections, which overturn is supported in a recess on the other side wall. It is thus achieved that during the height adjustment of the carrier, the upper side of the support does not bend inwardly owing to forces occurring, which are directed normal to the upper side. The end face may preferably be interrupted by at least one recess, which positively surrounds the at least one holding rod section-wise. According to claim 6, it is proposed that the preformed workpiece receives its U-shape with parallel side walls owing to double right-angled bending over in the region of the end face and that the sections of the preformed workpiece being used for the positive connection are then partially bent over toward one another. Owing to the method according to the invention, a tool-reducing production of the support is made possible, in which the use of additional connecting means, such as rivets or screws, or the application of additional connecting methods, such as welding or soldering, are dispensed with. Owing to the production according to the method, a comparable stability is achieved, that which can be achieved in supports according to the prior art. Advantageously, the preformed workpiece can be produced by stamping. The production of the preformed workpiece by stamping is economical and can be carried out in large numbers. Furthermore, the support can be stabilised by an end face section, which is produced during the stamping out of recesses from the region of the preformed workpiece, from which the end face is produced, and is arranged parallel to the end face by bending over. This preferably takes place in the region of the end face remote from the upper side, which can be used for connecting two supports to one another. A doubling of the wall thickness and therefore an increase in the stability in this region of the end face is thereby achieved. Further details of the invention are to be inferred hereinafter from an embodiment shown with the aid of the drawings, in which: Fig. 1 shows a side view of a support according to the invention; Fig. 2 shows a partially sectional detailed view A of the support according to Fig. 1. A support 1 implemented according to the invention, for a drafting arrangement of a textile machine can be inferred from the view in Fig. 1. The support 1 is used for receiving a carrier of the drafting arrangement, not shown. The carrier is pivotably mounted about a pivot pin, not shown, arranged on the support 1 in through-holes 10. To attach the carrier, the latter is fixed by means of the support 1 on holding rods, not shown, of the machine frame of the textile machine. The support 1 implemented in one piece has a substantially U-shaped contour. Moreover, the support 1 has an end face 3, which is interrupted by recesses 9, which are used for positively receiving the holding rods. Adjoining the end face 3 are side walls 2 which extend perpendicularly thereto and which are arranged parallel to one another. The through-holes 10 being used to receive the pivot pin are arranged flush with one another on the side walls 2 of the support 1. Furthermore, the support 1 has an upper side 4 extending perpendicularly to the end face 3 and to the side walls 2, which is configured by sections 5, 6 of the side walls 2 bent round at right angles. The sections 5, 6 extend here substantially over the length of the side walls 2, so the U-shaped support 1 is sealed upwardly, at least partially. Provided on the upper side 4 of the support 1 is a through-hole 7, which is used to receive an adjusting means, not shown, for height adjustment of the carrier. Furthermore, an overturn 8 is provided on the section 6, which extends perpendicularly to the section 6. The overturn 8 is supported in a correspondingly formed recess 11 of the side wall 2. This is used to receive the tensile force occurring during the height adjustment of the carrier, directed normal to the upper side 4, in order to prevent the upper side 4 being pressed in. Fig. 2 shows a detailed view A according to Fig. 1 of the support 1. A bent over end face section 12 can be inferred from the view and extends parallel to the end face 3 and rests thereon. The end face section 12 is provided with a through-hole 13, which is used to receive a connecting means for fixing the support 1 to a further support, not shown, in its position mounted on the holding rods. For this purpose, two end faces 3 of opposing supports 1 rest against one another and are connected to one another by means of a clamping sleeve, not shown, and the connecting means. For this purpose, the clamping sleeve extends through projections 14 which are arranged in each case in the region of the upper side 3 of the supports 1 and have through-holes 15 arranged flush to receive the clamping sleeve. Owing to the doubling of the wall thickness in the region remote from the upper side 4, of the end face 3, an additional reinforcement and stabilisation of the support 1 is achieved. The method according to the invention provides that a preformed workpiece, which is produced, for example by stamping, and is configured partially symmetrically, is used to produce the support 1. The workpiece, owing to the stamping out, already has correspondingly preformed contours of the sections 5, 6 of the overturn 8, of the end face section 12 or the recesses 9, 11. The end face section 12 is left inside the recess 9 when stamping out the workpiece. According to the invention the workpiece is initially bent over to form a substantially U-shaped profile, so the side walls 2 extend perpendicularly to the end face 3 and parallel to one another. Following this, the sections 5, 6 of the side walls 2 are formed by bending in such a way that they are arranged flush with one another, the sections 5, 6 being positively joined to one another. In this manner, the spatial form of the support 1 is produced. Furthermore, the overturn 8 of the one side wall 2 is brought positively in to engagement with the recess 11 of the other side wall 2. The sections 5, 6 positively joined to one another have a smaller overdimension here, so they are joined to one another like a press fit. CLAIM: 1. Support (1) which is used to receive a carrier for the utop rollers of a drafting arrangement and can be fixed to at least one holding rod on a machine frame of a textile machine, wherein the support (1) has a substantially U-shaped contour, which is produced from an end face (3) and side walls (2) which extend perpendicularly to the end face (3) and are parallel to one another, characterised in that - the support (1), for stabilisation, has sections (5, 6), which are angled perpendicularly to the end face (3) and the side walls (2), which are positively connected to one another, and - in that the spatial form of the support (1) is produced by bending. 2.

Description:
The present invention relates to a support for a drafting arrangement of a textile machine according to the preamble of claim 1 and a method for producing a support according to the preamble of claim 6.
A support for a carrier of a drafting arrangement is known from DE 39 02 859 Al and is produced by assembling two plates together, which are dimensioned accordingly for the loads occurring on the drafting arrangement. In this case, the two identically formed plates arranged parallel to one another are connected to one another by spacers.
Furthermore, a support configured in one piece with a U-shaped contour is known, which is produced from an end face and side walls which extend perpendicularly to the end face and parallel to one another. The support is produced by the use of a deep-drawing tool. The side walls are connected to one another on their side remote from the end face by spacers. This serves to stabilise the support, which is open on the side remote from the end face.
The outlay for stabilising the support, which occurs owing to the increased material assembly outlay and the use of expensive deep-drawing tools has proven disadvantageous in the above-mentioned prior art.
The invention is based on the object of providing a support for a carrier of a drafting arrangement, which is simple and economical to produce and can be implemented in a tool-reducing manner.
This is achieved, according to the invention, with respect to the support by the characterising features of claim 1 and with respect to the method by the characterising features of claim 6.

Further advantageous configurations are the subject of the sub-claims.
According to claim 1, it is proposed that the support, for stabilisation perpendicularly to the end face and the side walls has angled sections, which are connected to one another positively and in that the spatial form of the support is produced by bending. The support is stabilised by the sections which are positively connected to one another and extend at least section-wise over the length of the side walls, without the use of spacers or the like being necessary, as is the case in the prior art. The torques transmitted during operation of the drafting arrangement via the carrier onto the support can be better absorbed owing to the higher torsional rigidity of the support. Owing to the one-piece design of the support, the construction is simplified. In addition, the support according to the invention can be produced more economically as the use of expensive deep-drawing tools, which are subject to heavy wear in the production of a support according to the prior art, or the use of spacers or the like, is not necessary for stabilisation.
In particular, some of the sections which can be positively joined in to one another have a smaller overdimension. The connection of the sections can therefore take place by means of a press fit, so the use of additional connecting means, such as screws or rivets, or the use of other connecting methods, such as welding or soldering, can be dispensed with. This contributes to a reduction in the working steps required for production, so production of the support becomes more economical. In particular, suitable shaping of the sections positively joined to one another combined with the press fit, can achieve a frictional-positive connection of the side walls, which prevents the side walls being displaced relative to one another because of a force directed perpendicularly to them.
Furthermore, a through-hole to receive an adjusting means for height-adjustability of the carrier may be arranged on the upper side configured by the angled sections. The adjusting means can be configured as a screw, which is supported on the upper side of the support.

Furthermore, at least one overturn can be provided on one of the sections, which overturn is supported in a recess on the other side wall. It is thus achieved that during the height adjustment of the carrier, the upper side of the support does not bend inwardly owing to forces occurring, which are directed normal to the upper side.
The end face may preferably be interrupted by at least one recess, which positively surrounds the at least one holding rod section-wise.
According to claim 6, it is proposed that the preformed workpiece receives its U-shape with parallel side walls owing to double right-angled bending over in the region of the end face and that the sections of the preformed workpiece being used for the positive connection are then partially bent over toward one another. Owing to the method according to the invention, a tool-reducing production of the support is made possible, in which the use of additional connecting means, such as rivets or screws, or the application of additional connecting methods, such as welding or soldering, are dispensed with. Owing to the production according to the method, a comparable stability is achieved, that which can be achieved in supports according to the prior art.
Advantageously, the preformed workpiece can be produced by stamping. The production of the preformed workpiece by stamping is economical and can be carried out in large numbers.
Furthermore, the support can be stabilised by an end face section, which is produced during the stamping out of recesses from the region of the preformed workpiece, from which the end face is produced, and is arranged parallel to the end face by bending over. This preferably takes place in the region of the end face remote from the upper side, which can be used for connecting two supports to one another. A doubling of the wall thickness and therefore an increase in the stability in this region of the end face is thereby achieved.

Further details of the invention are to be inferred hereinafter from an embodiment shown with the aid of the drawings, in which:
Fig. 1 shows a side view of a support according to the invention;
Fig. 2 shows a partially sectional detailed view A of the support according to Fig. 1.
A support 1 implemented according to the invention, for a drafting arrangement of a textile machine can be inferred from the view in Fig. 1. The support 1 is used for receiving a carrier of the drafting arrangement, not shown. The carrier is pivotably mounted about a pivot pin, not shown, arranged on the support 1 in through-holes 10. To attach the carrier, the latter is fixed by means of the support 1 on holding rods, not shown, of the machine frame of the textile machine.
The support 1 implemented in one piece has a substantially U-shaped contour. Moreover, the support 1 has an end face 3, which is interrupted by recesses 9, which are used for positively receiving the holding rods. Adjoining the end face 3 are side walls 2 which extend perpendicularly thereto and which are arranged parallel to one another. The through-holes 10 being used to receive the pivot pin are arranged flush with one another on the side walls 2 of the support 1. Furthermore, the support 1 has an upper side 4 extending perpendicularly to the end face 3 and to the side walls 2, which is configured by sections 5, 6 of the side walls 2 bent round at right angles. The sections 5, 6 extend here substantially over the length of the side walls 2, so the U-shaped support 1 is sealed upwardly, at least partially.
Provided on the upper side 4 of the support 1 is a through-hole 7, which is used to receive an adjusting means, not shown, for height adjustment of the carrier. Furthermore, an overturn 8 is provided on the section 6, which extends perpendicularly to the section 6. The overturn 8 is supported in a correspondingly formed recess 11 of the side wall 2. This is used to receive the tensile force occurring

during the height adjustment of the carrier, directed normal to the upper side 4, in order to prevent the upper side 4 being pressed in.
Fig. 2 shows a detailed view A according to Fig. 1 of the support 1. A bent over end face section 12 can be inferred from the view and extends parallel to the end face 3 and rests thereon. The end face section 12 is provided with a through-hole 13, which is used to receive a connecting means for fixing the support 1 to a further support, not shown, in its position mounted on the holding rods. For this purpose, two end faces 3 of opposing supports 1 rest against one another and are connected to one another by means of a clamping sleeve, not shown, and the connecting means. For this purpose, the clamping sleeve extends through projections 14 which are arranged in each case in the region of the upper side 3 of the supports 1 and have through-holes 15 arranged flush to receive the clamping sleeve. Owing to the doubling of the wall thickness in the region remote from the upper side 4, of the end face 3, an additional reinforcement and stabilisation of the support 1 is achieved.
The method according to the invention provides that a preformed workpiece, which is produced, for example by stamping, and is configured partially symmetrically, is used to produce the support 1. The workpiece, owing to the stamping out, already has correspondingly preformed contours of the sections 5, 6 of the overturn 8, of the end face section 12 or the recesses 9, 11. The end face section 12 is left inside the recess 9 when stamping out the workpiece.
According to the invention the workpiece is initially bent over to form a substantially U-shaped profile, so the side walls 2 extend perpendicularly to the end face 3 and parallel to one another. Following this, the sections 5, 6 of the side walls 2 are formed by bending in such a way that they are arranged flush with one another, the sections 5, 6 being positively joined to one another. In this manner, the spatial form of the support 1 is produced.

Furthermore, the overturn 8 of the one side wall 2 is brought positively in to engagement with the recess 11 of the other side wall 2. The sections 5, 6 positively joined to one another have a smaller overdimension here, so they are joined to one another like a press fit.
