PREAMBLE TO THE DESCRIPTION The following specification particularly describes the invention and the manner in which it is to be performed : - The present invention relates to a turning bar for rotary printing machines and especially a transferable turning bar for usage in two roll running directions. By means of a turning bar the roll running direction of a printed news print roll, like e.g. of a paper roll, in a rotary printing machine is changed. The turning bar is pneumatically operated and develops on its external circumferential surface at least section-wise an air cushion, so that the printed news print roll does not come in direct contact with the turning bar equipment. From this emerge several advantages. Through the air cushion the friction while turning the printed news print roll is reduced. It does not cause getting the impression of color ink on the turning bar. And the print image of still wet printed news print roll is not smeared while turning the printed news print roll by the turning bar. Depending on the order it can be necessary to change the roll running direction of the printed news print roll. For example, it can be necessary, to deflect a printed news print roll for a particular print job in an angle of e.g. 90° to the right of the roll running direction and in case of another print job in an angle of 90° to the light. To meet these requirements, the use is known, from the state of technology, of the so called "flying" turning bars. The turning bar is fitted on to a holder as being un-mountable and for every required roll running direction specially finished turning bar is essential h means, a remounting from one turning bar to another available turning bar must follow. Besides the fact that thus for every roll running direction a separate turning bar must be produced, this solution means for the printing machine user also an increased logistical expenditure, because turning bars need to be stocked in the printing press store. The patent DE 34 36870 C l deals with above referred disadvantages. The patent application for public inspection discloses a turning bar suspended as rotatable. In this turning bar, in the inside of the turning bar two pistons, whose geometry 2 matches with the paper edge carried on around the outside of the turning bar, are pushed via separate spindles axial for closing of bores not required in the turning bar. The arrangement shown in DE 34 36 870 CI is less flexible with respect to roil widths to be handled and has disadvantages pertaining to the build up of the air cushion on the turning bar. Based on the said state of technology it is the task of the present invention, to provide a turning bar, which has an alternative mechanism for handling variable roll widths with improved air cushion formation from the point of view of overall flow. Claim 1 of the present invention resolves this task. The dependent claims are advantageous designs of the invention. The invention is based on a turning bar for a rotary printing machine for turning a printed news print roll in several roll running directions. The turning bar has in this an external pipe, in which at least one internal pipe is arranged. The turning bar is impacted from inside towards outside with compressed air, so that through air passage opening^ which are located in the inside pipe as well as in the outer pipe, an air cushion i^ formed on the circumferential side of the outer surface of the turning bar. Since the air passage openings in the internal pipe and in the outer pipe are matched on each other in $Uch a way that through adjusting either the inner pipe to match the outer pipe or the outer pipe to match the inner pipe each time a common air passage opening of the turning bar emerges. Through matching of individual air passage openings of the pipes with each other, a finer and flow-wise effective matching of the turning bar to suit roll width changes is enabled. Further, the air passage openings can be adjusted in such a way that the turning bar can be transferred for 3 changing the roll running direction and according to the same the air passage openings can be matched with the changed roll running direction. This means, after change of roll running direction or transfer of turning bar through adjustment of air passage openings to match each other, non-required air passage openings are closed, so that the emerging air cushion is matched to suit also the changed flow pattern of the side edges of the printed news print roll on the turning bar. According to a design form of the invention the outer pipe and the inner pipe are rotatable with respect to each other and/or adjustable axially with respect to each other. For adjusting the air passage openings of the outer or the inner pipe basically any possible mechanism can be used, as far as a suitable closing of the non-required air passage openings is made possible. For realization of the invention, further it is not significant, whether the outer pipe can be adjustable relative to the internal pipe or the internal pipe relative to the outer pipe, or whether both the pipes are designed as being adjustable. According to an advantageous design of the invention in the outer pipe bores and in the inner pipe slots in circumferential direction have been developed. Through the allocation of slots in the inner pipe and bores in the outer pipe and through a setting direction of the inner pipe matching to the position of the turning bar relative to the outer pipe, a closure of the non-required air passage openings is possible, which is matched with the respective position of the turning bar. For example, the use of the same turning bar for two paper running directions is possible and thus only one turning bar is required for both the roll running directions in the printing press operation. According to another design of the invention the slots in the internal pipe are developed longer towards the turning bar center. Through the slots developed with different lengths it is ensured that in case of rotary adjustment of the internal pipe with respect to the outer pipe the air passage openings on the roll width of the printed news print roll can be matched. This means, in case of rotary adjustment of 4 the inner pipe first the air passage openings at the outer side of the turning bar are closed and only with further rotation in the same direction towards air passage arranged towards the center. According to another design of the invention the inner pipe is adjustable vis-a-vis the outer pipe in such a way that the air outlet at an outer partial area of a single end of the turning bar is prevented. This is ensured by the fact that the inner pipe is pushed axial to the outer pipe. The slots in this design form are developed broader than the bore diameter of the bores of the outer pipe. The bores are allocated to the slots in such a way that during axial shift of the inner pipe the air passage openings of an outer partial area of the turning bar get closed. Further it is possible to divide the inner pipe, so that two inner pipes exist and only one of the pipes gets axially shifted. In this arrangement the width of slots in all inner pipes can be equal. Thus it is achieved that during the axial shifting of an inner pipe the air passage openings in the area of the turning bar above this inner pipe get completely closed. Through the closing of the air passage openings of an outer partial area, like e.g. of the half of the turning bar, a production with a half printed news print roll located inside or outside is possible. According to another advantageous design of the invention a supporting arrangement is provided for quick and easy transfer of turning bar according to the roll running direction and adjusting drives facilitate or automate the transfer of the turning bar. Further, another adjusting drive can be foreseen for the adjustment of pipes with respect to each other. The present invention is described in detail with help of the following figures. These show: Figure 1 A cross section view of the position of the turning bar for deflecting the printed news print roll to the right; Figure 2 A cross section representation, which clearly shows the process of transferring the turning bar; 5 Figure 3 A cross section view of position of the turning bar for deflecting the printed news print roll to the left; Figure 4 The development of the turning bar of a first design form with inner and outer pipe; Figure 5 The development of the turning bar of a first design form with inner and outer pipe, set for a changed roll running direction in comparison to Figure 4; Figures 6,7 A development of the turning bar of a first design form with an example of a setting for a narrow printed news print roll; Figure 8 A development of the turning bar of a second design form with a first, axial shifted inner pipe for the production with a half printed news print roll; Figure 9 a development of the turning bar of a second design form with a second, axial shifted inner pipe for the production with a half printed news print roll on the opposite turning bar side in comparison to Figure 8; Figure 10 a development of the turning bar a third design form with broader slots in the inner pipe; Figure 11 a development of the turning bar of a third design form, wherein the air passage openings of the left side are closed; Figure 12 a development of the turning bar of a third design form, wherein the air passage openings of the right side are closed; 6 Figure 13 An adjusting mechanism for the rotational and axial adjustment of the inner pipe In Figure 1 a turning bar 1 is shown, which guides the printed news print roll to the right. At the end of the turning bar an adjustment mechanism is arranged, which serves for the rotational and axial adjustment of the inner pipe 3 vis-a-vis the outer pipe 19. As shown in Figure 2, a transfer of the turning bar for the production in opposite roll running direction is possible. For this purpose a first part 15 of the support arrangement 18 is relieved from a second part 17 by loosening the corresponding fixing screws, which join the supporting parts 15,17. The first part 15 of the support arrangement 18 and the second part 17 of the support arrangement 18 are still joined through an axis 16 with each other after the separation of the supporting parts. The position the axis 76- if selected in such a way that the turning bar can be swung in a particular way that no center offset of the paper roll 6 emerges after the deflection. The air feed to the turning bar 1 follows via the axis 16 in such a way that no further components need to be coupled afresh for transferring turning bar. Figure 3 shows the turning bar in a position for the production with a paper roll 6 deflected to the left side. Figure 4 shows the development of an outer pipe 19 and a development of the inner pipe 3 lying below it. In the outer pipe 19 bores 2 are developed, to each of which one slot 4 in the inner pipe is allocated. For a maximum paper roll width to be handled all air passage openings 2, 4 for a selected i-0ll running direction are open. For this purpose both the pipes are in the position „RO" 5, which is displayed at the turning bar by means of a suitable scale. Reference Symbol 7 shows the width areas of the turning bar that can be shut off, which can be opened or closed for the setting on a corresponding paper roll 6. Figure 5 shows a representation matching the Figure 4 with roll running direction to the left, i.e. here the position "LO" 8 of the turning bar is set, so that the air passage openings a.re closed according to the side edges of the paper roll 6. 7 Figures 6 and 7 show, for example, the settings "R3" 9 and "L3" 10 for a relatively narrow printed news print roll. In Figure 8 another design form of the invention is represented, in which two inner pipes 3' and 3" are provided. The usage of two inner pipes serves the purpose of closing the air passage openings 2, 4 of one half of the turning bar, so that production can be carried out with a half roll. Through an axially shifted inner pipe 3' or 3", independent of the radial position of the inner pipe, all bores 2 of the outer pipe 19 are closed. The Figures 10 to 12 show a design form with only one inner pipe, wherein the slots 4 are developed broader than the diameter of a bore 2. The allocation of bores to the slots in fully opened condition is such that each of the bores, towards the center of the turning bar, is on the side of the slot lying inside. Thereby, it becomes possible, to close half of the turning bar at a time by axial shifting in the Figures 11 and 12 shown with arrows, so that production can be carried out with half the paper roll. Figure 13 shows the adjustment mechanism for the axial and radial shifting of the inner pipe 3', 3" vis-a-vis the outer pipe 19. The radial adjustment follows via a rotary knob 11, which is joined with a spindle 12 for a rotational drag of two inner pipes 3', 3". The rotary knob 11 has a position indication (not represented here). Further, latching elements 13 for fixing of position of the inner pipe 3',3" in radial and axial direction are shown. The axial adjustment of the inner pipes 3',3" is done via an axially shift able setting element 14 with corresponding position fixing. In the position "A" both the inner pipes 31,3" are located in such a way that a printed news print roll can be run in the center position over the turning bar, since in position "A" the inner pipes are separate and thereby all air passage openings 2,4 set on a particular width are open. In position "B" the inner pipe 3' is shifted axial to the center and thus the air passage openings in the half of the turning bar above the inner pipe 31 are closed. In position "C" the inner pipe 3" is pushed through 8 connecting set elements in the turning bar towards the center and the inner pipe 31 is again in its initial position (refer Position "A"). Hereby the inner pipe 3" with respect to its initial position is pushed axial and thus the air passage openings in the half of the turning bar above the inner pipe 3" are closed.

Figure 13 An adjusting mechanism for the rotational and axial adjustment of the inner pipe
In Figure 1 a turning bar 1 is shown, which guides the printed news print roll to the right. At the end of the turning bar an adjustment mechanism is arranged, which serves for the rotational and axial adjustment of the inner pipe 3 vis-a-vis the outer pipe 19. As shown in Figure 2, a transfer of the turning bar for the production in opposite roll running direction is possible. For this purpose a first part 15 of the support arrangement 18 is relieved from a second part 17 by loosening the corresponding fixing screws, which join the supporting parts 15,17. The first part 15 of the support arrangement 18 and the second part 17 of the support arrangement 18 are still joined through an axis 16 with each other after the separation of the supporting parts. The position the axis 76- if selected in such a way that the turning bar can be swung in a particular way that no center offset of the paper roll 6 emerges after the deflection. The air feed to the turning bar 1 follows via the axis 16 in such a way that no further components need to be coupled afresh for transferring turning bar. Figure 3 shows the turning bar in a position for the production with a paper roll 6 deflected to the left side.
Figure 4 shows the development of an outer pipe 19 and a development of the inner pipe 3 lying below it. In the outer pipe 19 bores 2 are developed, to each of which one slot 4 in the inner pipe is allocated. For a maximum paper roll width to be handled all air passage openings 2, 4 for a selected i-0ll running direction are open. For this purpose both the pipes are in the position „RO" 5, which is displayed at the turning bar by means of a suitable scale. Reference Symbol 7 shows the width areas of the turning bar that can be shut off, which can be opened or closed for the setting on a corresponding paper roll 6. Figure 5 shows a representation matching the Figure 4 with roll running direction to the left, i.e. here the position "LO" 8 of the turning bar is set, so that the air passage openings a.re closed according to the side edges of the paper roll 6.

Figures 6 and 7 show, for example, the settings "R3" 9 and "L3" 10 for a relatively narrow printed news print roll.
In Figure 8 another design form of the invention is represented, in which two inner pipes 3' and 3" are provided. The usage of two inner pipes serves the purpose of closing the air passage openings 2, 4 of one half of the turning bar, so that production can be carried out with a half roll. Through an axially shifted inner pipe 3' or 3", independent of the radial position of the inner pipe, all bores 2 of the outer pipe 19 are closed.
The Figures 10 to 12 show a design form with only one inner pipe, wherein the slots 4 are developed broader than the diameter of a bore 2. The allocation of bores to the slots in fully opened condition is such that each of the bores, towards the center of the turning bar, is on the side of the slot lying inside. Thereby, it becomes possible, to close half of the turning bar at a time by axial shifting in the Figures 11 and 12 shown with arrows, so that production can be carried out with half the paper roll.
Figure 13 shows the adjustment mechanism for the axial and radial shifting of the inner pipe 3', 3" vis-a-vis the outer pipe 19. The radial adjustment follows via a rotary knob 11, which is joined with a spindle 12 for a rotational drag of two inner pipes 3', 3". The rotary knob 11 has a position indication (not represented here). Further, latching elements 13 for fixing of position of the inner pipe 3',3" in radial and axial direction are shown. The axial adjustment of the inner pipes 3',3" is done via an axially shift able setting element 14 with corresponding position fixing.
In the position "A" both the inner pipes 31,3" are located in such a way that a printed news print roll can be run in the center position over the turning bar, since in position "A" the inner pipes are separate and thereby all air passage openings 2,4 set on a particular width are open. In position "B" the inner pipe 3' is shifted axial to the center and thus the air passage openings in the half of the turning bar above the inner pipe 31 are closed. In position "C" the inner pipe 3" is pushed through
8

connecting set elements in the turning bar towards the center and the inner pipe 31 is again in its initial position (refer Position "A"). Hereby the inner pipe 3" with respect to its initial position is pushed axial and thus the air passage openings in the half of the turning bar above the inner pipe 3" are closed.

Abstract
Pneumatic actuated turning bar 3,19 of a rotary printing machine for deflecting a printed news print roll 6 in two roll running directions. The pneumatic actuated turning bar 3,19 is structured from at least one inner pipe 3 and one outer pipe 19, both of which have air passage openings 2,4 tuned to each other, in order to form an air cushion above the turning bar. Through an adjustment of the inner pipe 3 vis-avis the outer pipe 19 the air passage openings 2,4 can be closed in such a way that the air cushion is matched on the side edges of the printed news print roll 6. Thus a usage of the turning bar in both the roll running directions is possible.
