Abstract

A textile tool part pair ( 15 ) consisting of two textile tool parts ( 16 ) and a method of equipping a textile machine with the aid of such a textile tool part pair ( 15 ) are disclosed. Each textile tool part ( 16 ) extends in a longitudinal direction (L) between a trailing end ( 21 ) and a leading end ( 22 ). Proceeding from the trailing ends ( 21 ) thereof, the textile tool parts ( 16 ) extend away from one another and counter to one another as far as the leading end ( 22 ). At the trailing ends ( 21 ), the two textile tool parts ( 16 ) of a common textile tool part pair ( 15 ) are interconnected by a predetermined breaking connection ( 45 ). The predetermined breaking connection ( 45 ) can be manually separated without tools, in particular by bending about a bending axis (A).

First claim

The invention claimed is:

1. A textile tool part pair ( 15 ) consisting of two textile tool parts ( 16 ), the two textile tool parts comprising:
bodies of the two textile tool parts ( 16 ) that are respectively configured for insertion in a guide channel or a tool seating of a textile machine;
wherein each of the two textile tool part ( 16 ) bodies extends in a longitudinal direction (L) between a front end ( 22 ) and a back end ( 21 ) and comprises a working section ( 25 ) that is arranged at a distance to the back end ( 21 ) configured to be used for thread contact and/or loop formation;
wherein the two textile tool part ( 16 ) bodies are connected with each other at their back ends ( 21 ) by a breaking connection ( 45 ) that is configured to be separated manually and without use of tools;
wherein the textile tool part ( 16 ) bodies extend away from each other from the breaking connection ( 45 ) to their respective front end ( 22 );
wherein the breaking connection ( 45 ) comprises at least one web ( 46 ) that extends between the two back ends ( 21 ) of the two textile tool part ( 16 ) bodies; and
wherein the two textile tool part ( 16 ) bodies and the at least one web ( 46 ) of the breaking connection ( 45 ) are of a metal or metal alloy material.

2. The textile tool part pair according to claim 1 , wherein the breaking connection ( 45 ) has a smaller cross-sectional area compared with the back ends ( 21 ) of the two textile tool part ( 16 ) bodies.

3. The textile tool part pair according to claim 2 , wherein the at least one web ( 46 ) is configured integrally with the two textile tool part ( 16 ) bodies.

4. The textile tool part pair according to claim 2 , wherein the at least one web ( 46 ) extends between two end surfaces ( 47 ) of the back ends ( 21 ) facing one another.

5. The textile tool part pair according to claim 1 , wherein the breaking connection ( 45 ) is configured to allow a bending of the textile tool parts ( 16 ) around a bending axis (A) extending orthogonal to the longitudinal direction (L).

6. The textile tool part pair according to claim 1 , wherein each of the two textile tool part ( 16 ) bodies has a base surface ( 31 ) that extends along a common reference plane (E) that is defined by the longitudinal direction (L) and a transverse direction (Q) transverse to the longitudinal direction (L).

7. The textile tool part pair according to claim 6 ,
wherein the breaking connection ( 45 ) is configured to allow a bending of the textile tool parts ( 16 ) around a bending axis (A) extending orthogonal to the longitudinal direction (L), wherein the bending axis (A) extends orthogonal to the base surfaces ( 31 ) of the textile tool part ( 16 ) bodies.

8. The textile tool part pair according to claim 7 , wherein the common reference plane (E) is a contact plane that is brought into contact with the textile tool part pair ( 15 ) from below until the base surfaces ( 31 ) extend in the common reference plane (E), whereby no components of the textile tool part pair ( 15 ) extend through the common reference plane (E).

9. The textile tool part pair according to claim 1 , wherein each of the two textile tool part ( 16 ) bodies comprises an abutment surface ( 49 ), wherein the abutment surfaces ( 49 ) are arranged at a distance to each other prior to separation of the breaking connection ( 45 ) and are configured to be brought into abutment against each other after separation of the breaking connection ( 45 ), such that the two textile tool parts ( 16 ) form a textile tool ( 18 , 19 ).

10. The textile tool part pair according to claim 9 , wherein the textile tool formed from the two textile tool parts ( 16 ) is a sinker ( 18 ) for a knitting machine.

11. A method for equipping a textile machine with the textile tool part pair ( 15 ) of claim 1 , the method comprising the following steps:
separating the two textile tool parts ( 16 ) of the textile tool part pair ( 15 ) at the breaking connection ( 45 ) manually without use of tools; and
inserting the separated textile tool parts ( 16 ) in a guide channel ( 42 ) or a tool seating of the textile machine.

12. The method according to claim 11 , wherein separating the two textile tool parts ( 16 ) of the textile tool part pair ( 15 ) manually without use of tools is carried out by bending around a bending axis (A) that extends between the two back ends ( 21 ) of the two textile tool parts ( 16 ).

13. The method according to claim 12 , wherein the two separated textile tool parts ( 16 ) are inserted in the respective guide channel ( 42 ) or the tool seating without further post-processing.

14. The textile tool part pair according to claim 1 , wherein a height of the at least one web ( 46 ) is smaller than a height of the back ends ( 21 ) of the bodies of the two textile tool parts ( 16 ).

15. The textile tool part pair according to claim 1 , wherein a thickness of the at least one web ( 46 ) is smaller than a thickness of the back ends ( 21 ) of the bodies of the two textile tool parts ( 16 ).

16. The textile tool part pair according to claim 1 , wherein the at least one web ( 46 ) comprises at least two webs ( 46 ) that are spaced apart from one another in a height direction (H), wherein the height direction (H) is orthogonal to the longitudinal direction (L).
