Abstract

A heddle ( 10 ) is provided for weaving strip-shaped warp yarn. Said heddle ( 10 ) includes a heddle shaft ( 12 ) formed by two shaft parts ( 13 ). Said shaft parts ( 13 ) are placed on top of each other in a respective end section ( 15 ) of the heddle shaft ( 12 ) and interconnected. The end eyelets ( 16 ) of the heddle ( 10 ) are also in said end section ( 15 ). To form a yarn eye between both shaft parts ( 13 ), two separate warp yarn guiding bodies ( 20 ) are placed therebetween. To determine the position of the warp yarn guiding body ( 20 ) with respect to the heddle shaft ( 12 ), at least one shaft projection ( 22 ) is produced by stamping and subsequent bending or embossing each shaft part ( 13 ) for each warp yarn guiding body ( 20 ). Said shaft projection ( 22 ) engages in an associated recess ( 25 ) of the warp yarn guiding body ( 20 ), and a bonding connection is produced.

First claim

The invention is:

1. A heddle ( 10 ) for a loom, the heddle comprising:
a heddle shaft ( 12 ) having two end sections ( 15 ), each end section having a respective end eyelet ( 16 );
two separate shaft parts ( 13 ) of the heddle shaft extending, at least in sections, spaced-apart from each other,
at least two spaced apart warp yarn guiding bodies ( 20 ) formed from a single ring element or separate bodies that are arranged between the two shaft parts ( 13 ) and delimits a yarn eye ( 11 ) for a warp yarn,
wherein each shaft part ( 13 ) is provided with at least one shaft projection ( 22 ) produced by stamping and/or bending and/or embossing, said shaft projection engaging in a respective associated recess ( 25 ) on one of the at least two spaced apart warp yarn guiding bodies ( 20 ) in order to position the one of the at least two spaced apart warp yarn guiding bodies ( 20 ) on the heddle shaft ( 12 ) or to fasten it thereto.

2. The heddle as in claim 1 , wherein the two shaft parts ( 13 ) are strip-shaped.

3. The heddle as in claim 1 , wherein individual ones of the at least two spaced apart at least one warp yarn guiding bodies ( 20 ) are connected to the two shaft parts ( 13 ) in a material-bonded manner.

4. The heddle as in claim 1 , wherein the ( 20 ) single ring element includes the yarn eye ( 11 ), or two of the at least two spaced-apart warp yarn guiding bodies ( 20 ) extending in an extension direction (E) of the heddle shaft ( 12 ) delimit the yarn eye ( 11 ) on one upper side and one lower side.

5. The heddle as in claim 1 , wherein the shaft projection ( 22 ) is connected to the shaft part ( 13 ) without any gaps in a circumferential direction.

6. The heddle: as in claim 1 , wherein the shaft projection ( 22 ) is formed by a latch ( 23 ) that is exposed from the shaft part ( 13 ) by stamping.

7. The heddle as in claim 1 , wherein at least one of the at least two warp yarn guiding bodies ( 20 ) has two sides with one extension ( 27 ) on each of both sides, and each extension engaging in a recess ( 28 ) on a respective associated shaft part ( 13 ).

8. The heddle as in claim 7 , wherein each extension ( 27 ) transitions without offsets in a guiding surface ( 21 ) configured for support of warp yarn, or that a transition surface ( 27 a ) extending essentially along an adjacent shaft part ( 13 ) inside the yarn eye ( 11 ) is provided, said transition surface connecting the guiding surface ( 21 ) and the extension ( 27 ) without gaps.

9. The heddle as in claim 1 , wherein at least one of the at least two warp yarn guiding bodies ( 20 ) tapers in an extension direction (E) of the heddle shaft ( 12 ) away from the yarn eye ( 11 ).

10. The heddle as in claim 9 , wherein the at least one of the at least two warp yarn guiding bodies ( 20 ) has one lateral surface ( 26 ) extending, at least in sections, in an inclined or arcuate manner relative to the extension direction (E).

11. The heddle as in claim 10 , wherein the lateral surface ( 26 ) has a first surface section ( 26 a ) and a second surface section ( 26 b ) which form different angles of inclination (α 1 , α 2 ) relative to the extension direction (E).

12. The heddle as in claim 1 , wherein at least one of the at least two warp yarn guiding bodies ( 20 ) has, in a lateral surface ( 26 ) associated with the respective shaft part ( 13 ), at least one flow groove ( 38 ) for distribution of glue.

13. The heddle as in claim 1 , wherein at least one of the at least two warp yarn guiding bodies ( 20 ) has a glue reservoir ( 35 ) that is open to a lateral surface ( 26 ) associated with the respective shaft part ( 13 ).

14. The heddle as in claim 13 , wherein the recess ( 25 ) on the one of the at least two warp yarn guiding bodies ( 20 ) acts as the glue reservoir ( 35 ).

15. The heddle as in claim 13 , wherein the glue reservoir ( 35 ) terminates at a filling opening ( 37 ) on a rear side ( 31 ) of the one of the at least two warp yarn guiding bodies ( 20 ), said rear side facing away from a guiding surface ( 21 ) configured for the support of warp yarn.

16. A method for the production of a heddle ( 10 ) for a loom, in particular a circular loom, wherein the heddle ( 10 ) has a heddle shaft ( 12 ) having two end sections ( 15 ), each end section having a respective end eyelet ( 16 ) and the heddle shaft has two shaft parts ( 13 ) extending, at least in sections, spaced-apart from each other, and wherein the heddle ( 10 ) has at least two spaced apart warp yarn guiding bodies ( 20 ) formed from a single ring clement or separate bodies that are arranged between the two shaft parts ( 13 ) and delimits a yarn eye ( 11 ) for a warp yarn, the method comprising:
producing at least one shaft projection ( 22 ) on each shaft part ( 13 ) by stamping and/or bending and/or embossing and connecting the two shaft parts ( 13 ) at least in the two end sections ( 15 ) of the heddle shaft ( 12 ),
arranging and/or fastening at least one of the at least two warp yarn guiding bodies ( 20 ) between the two shaft parts ( 13 ) in such a manner that the at least one shaft projection ( 22 ) of each shaft part ( 13 ) engages in a respective associated recess ( 25 ) on the at least one of the at least two warp yarn guiding bodies ( 20 ).
