Abstract

The invention relates to a tool module ( 10 ) having a module body ( 11 ), which has a contact surface ( 21 ) and an orienting structure ( 22 ). A fastening opening ( 29 ) and additionally at least one, preferably a plurality of additional openings ( 33, 34 ) extend through the contact surface ( 21 ). The area of one additional opening ( 33 ) or ( 34 ) is larger than, preferably considerably larger than, for example at least twice or three times as large as the cross-sectional area of the fastening opening ( 29 ). Thus, a module body ( 11 ) is provided, by means of which an increased operating speed of the textile machine can be achieved.

First claim

1 . Tool module ( 10 ), particularly for tufting applications
having a module body ( 11 ) that comprises an alignment structure ( 22 ) including an abutment surface ( 21 ) for positioning at a bar, having tools ( 12 - 18 ) held in the module body ( 11 ), having a fastening opening ( 29 ) that penetrates the abutment surface ( 21 ) and the module body ( 11 ), characterized by at least one additional opening ( 33 , 34 ) that penetrates the abutment surface ( 21 ) and the module body ( 11 ) and that is separated from the fastening opening ( 19 ).

2 . Tool module according to claim 1 , characterized in that the abutment surface ( 21 ) is configured in a flat manner.

3 . Tool module according to any of the preceding claims, characterized in that the alignment structure ( 22 ) comprises projections ( 23 , 24 ) extending away from the abutment surface ( 21 ).

4 . Tool module according to claim 3 , characterized in that two prismatic, cylinder-shaped or dome-shaped projections ( 23 , 24 ) are part of the projections ( 23 , 24 ) that extend parallel to each other away from the abutment surface ( 21 ).

5 . Tool module according to any of the claims 1 - 3 , characterized in that an interrupted or continuous ridge ( 26 ) is part of the alignment structure ( 22 ) adjoining a narrow surface ( 20 ) of the module body ( 11 ) and extending beyond the abutment surface ( 21 ).

6 . Tool module according to claims 4 and 5 , characterized in that the projections ( 23 , 24 ) are arranged on one line ( 28 ) that is orientated parallel to the ridge ( 26 ).

7 . Tool module according to claim 6 , characterized in that the fastening opening ( 29 ) is arranged on the line ( 28 ).

8 . Tool module according to any of the preceding claims, characterized in that the fastening opening ( 29 ) is configured in an insert ( 30 ) provided with an inner thread.

9 . Tool module according to any of the preceding claims, characterized in that the at least one additional opening ( 33 , 34 ) of the module body ( 11 ) is arranged in a zone between the fastening opening ( 29 ) and the ridge ( 26 ) arranged a small side ( 20 ) of the module body ( 11 ) and serves as alignment structure ( 22 ).

10 . Tool module according to any of the preceding claims, characterized in that two additional openings ( 33 , 34 ) are provided that are separate from the fastening opening ( 29 ).

11 . Tool module according to claim 10 , characterized in that the two openings ( 33 , 34 ) are configured mirror symmetrically to each other.

12 . Tool module according to claims 6 and 10 , characterized in that the additional openings ( 33 , 34 ) are arranged on a line that is parallel to a line ( 28 ) on which the projections ( 23 , 24 ) are arranged.

13 . Tool module according to any of the preceding claims, characterized in that the module body ( 11 ) is separated in a fastening section ( 31 ) and a tool holding section ( 32 ) by the at least one additional opening ( 33 , 34 ) that are connected with each other via at least two webs ( 33 , 38 , 39 ).

14 . Tool module according to claim 13 , characterized in that at least two webs ( 37 , 38 , 39 ) comprise substantially equal cross-sections.

15 . Tool module according to any of the preceding claims, characterized in that the module body ( 11 ) is a mold part.
