Tooth clothing for textile machines, such as combing machines, drafting and opening rollers of open-end devices and the like, comprising a plurality of bars of parallel, side-by-side saw-tooth cutouts which, by way of a foot-region recess, are pushed on to a holding member, having positive fit, and which, in the position of use, are retained in the longitudinal direction of the holding member by cheeks of the supporting segment or the roller, characterized in that the recesses (7) of the saw-tooth cutouts (1) and the cross section of the holding member (6) are approximately T-shaped at least sectionally, having two defining surfaces (9,10) which, at least by sections, are approximately parallel or acute-angled.

Tooth Clothing for Textile-Machine Rollers and Supporting Segments
The invention relates to textile-machine tooth clothing, such as for comb-
ing machines, drafting and opening rollers of open-end devices and the
like, comprising a plurality of bars of parallel, side-by-side saw-tooth cut-
outs which, by way of a foo :-region recess, are pushed on to a holding
member, having positive fit, and which, in the position of use, are retained
in the longitudinal direction of the holding member by cheeks of the sup-
porting segment or the roller.
DE 30 07 245 C2 describes tooth clothing of the generic type, the holding
member of dove-tail or approximately rectangular cross-sectional shape
being provided with side pieces in the shape of a segment of a circle.
This kind of fastening has been extraordinarily successful in practice, with
however the side-piece surfaces and circle segments leading to positioning
tolerances of the combing tips. The same applies to a type of fastening
known from EP 0 839 934 A1.
Experience having shown that, for optimal combing results, accurate, uni-
form positioning of the tips of combing segments is of outstanding impor-
tance, it is an object of the invention to improve the geometry of fastening
in such a way that those tolerances are considerably reduced.
According to the invention, this object is attained in that the recesses of the
saw-tooth cutouts and the cross section of the holding member are T-
shaped at least sectionally, 1 aving two defining surfaces of at least section-
ally parallel extension.

The T-shaped configuration according to the invention i.e., an arrangement
with two sections in parallel to each other, provides for minimization of
tolerances in the radial direction, which is the direction that involves the
position in height of the tips and the radial distance from the axis of rota-
tion. Tests have shown that it is possible to reduce the tolerances by half as
compared to prior art embodiments, which improves the combing result.
The design according to the invention enables the saw-tooth segments to be
put into practice in one piece and at a low cost, ensuring accurate, exclu-
sively positive positioning, there being no need for additional spring-
loading.
Details of the invention will become apparent from the ensuing description
of a preferred embodiment, taken in conjunction with the drawing which is
a diagrammatic illustration of tooth clothing according to the invention.
The drawing illustrates a complete saw-tooth cutout 1 which includes a
foot region 2 and a plurality of teeth 3. Further teeth 3 of saw-tooth cutouts
1 located behind them are roughly outlined on the right in the drawing, by
way of recesses 4 and linking rods (not shown) forming a bar 5.
DE 30 07 245 A1 describes details of the way in which these saw-tooth
cutouts 1 or a plurality of bars 5 are mounted on a combing cylinder of a
combing machine, in particular specifying the job of a holding member 6.
Each saw-tooth cutout 1 has a recess 7 so that the saw-tooth cutouts 1 or
bars 5 formed by a plurality thereof can be pushed on to the fastening por-
tion 8 of the holding member 6.

The fastening portion 8 of the holding member 6 has a cross-sectional
shape of a T, which means that it comprises two surfaces 9, 10 that, related
to the combing cylinder, extend approximately tangentially and in parallel
to each other and two defining surfaces 11 that, related to the combing cyl-
inder, extend approximately radially and in parallel to each other.
As compared to conventional, dove-tail configurations, this helps achieve
substantially lower tolerances in the radial direction (radius R) so that the
teeth 3 of the saw-tooth cutcuts 1 are positioned accurately and more uni-
formly, ensuring improved combing results.
