Abstract

A heddle ( 1 ), preferably for the processing of tape-like material, includes at least two bands ( 2, 3 ), which form the heddle shaft ( 24 ). At least one component ( 6, 7 ), which limits a thread eye ( 8 ), or one of the two bands ( 2, 3 ) has at least one fastening element ( 9, 10 ), which connects the component and the band. The two bands ( 2, 3 ) make mutual contact above and below the thread eye ( 8 ) at joins ( 13, 14 ). At least one join ( 13, 14 ) is spaced from the thread eye ( 8 ) by a distance A, which is, at the most, half as great as the distance (D) between the thread eye ( 8 ) and the end loop ( 17 ) nearest in each case to the join ( 13, 14 ).

First claim

The invention claimed is:

1. A heddle comprising:
at least two bands ( 2 , 3 ), which form a heddle shaft ( 24 ),
at least one component ( 6 , 7 ), which limits a thread eye ( 8 ),
at least two end loops ( 17 )
wherein the at least one component ( 6 , 7 ) has at least one fastening element ( 9 , 10 ) that engages ( 9 , 10 ) a recess ( 11 , 12 ) in a first of the at least two bands, and/or at least one of the two bands ( 2 , 3 ) has at least one fastening element ( 25 ) that interlocks with at least one component ( 6 , 7 ),
wherein the at least two bands ( 2 , 3 ) forming the heddle shaft ( 24 ) make mutual contact, at least section-wise, above and below the thread eye ( 8 ) at joins ( 13 , 14 ),
and wherein at least a first ( 13 ) of the joins above the thread eye or at least a second join ( 14 ) of the joins below the thread eye ( 8 ) is spaced from the thread eye ( 8 ) by a distance (A) which is less than half a distance (D) between the thread eye ( 8 ) and an end loop ( 17 ) of the least two end loops nearest to the respective join ( 13 , 14 ).

2. The heddle of claim 1 wherein the distance (A) is less than a third of the distance (D).

3. The heddle of claim 1 wherein the distance (A) is less than half the distance (D).

4. The heddle of claim 1 wherein the at least one component ( 6 , 7 ) limiting the thread eye ( 8 ) is held between the at least two bands ( 2 , 3 ) at least by a force perpendicular to a longitudinal direction (L) of the heddle.

5. The heddle of claim 1 wherein in its fitted position in the heddle ( 1 ), at least one of the at least two bands ( 2 , 3 ) is in a mechanically stressed state between the joins ( 13 , 14 ).

6. The heddle of claim 1 wherein the at least one component ( 6 , 7 ) limiting the thread eye ( 8 ) interlocks, by way of a fastening element ( 9 , 10 ), with at least one of the at least two bands ( 2 , 3 ) and has a contact surface ( 19 ) which makes contact with the at least one of the at least two bands and which opposes movement of the at least one component ( 6 , 7 ) towards the at least one of the at least two bands ( 2 , 3 ) when the at least one component ( 6 , 7 ) is in a fitted position.

7. The heddle of claim 1 wherein at least two components ( 6 , 7 ), which limit the thread eye ( 8 ) and which each have at least one fastening element ( 9 , 10 ) that interlocks ( 9 , 10 ) with at least one of the at least two bands ( 2 , 3 ).

8. The heddle of claim 6 wherein the at least one component ( 6 , 7 ) limiting the thread eye ( 8 ) interlocks by way of at least two fastening elements ( 9 , 10 ) with at least one of the at least two bands ( 2 , 3 ), and
wherein the at least one contact surface ( 19 ) is between the at least two fastening elements ( 9 , 10 ).

9. The heddle of claim 6 wherein:
the contact surface ( 19 ) runs largely parallel to a surface of the one of the at least two bands ( 2 , 3 ) with which it makes contact ( 19 ),
two of the fastening elements ( 9 , 10 ) are raised relative to the contact surface ( 19 ),
at least one of the two fastening elements ( 9 , 10 ) rises, along a rising surface, relative to the contact surface ( 19 ), and
the contact surface ( 19 ) and the rising surface ( 22 ) of the at least one of the two fastening elements ( 9 , 10 ) include an angle (β), which deviates from a right angle.

10. The heddle of claim 9 wherein the rising surface ( 22 ) of the at least one fastening element ( 10 ) is on a side of the fastening element ( 10 ) facing towards the thread eye ( 8 ).

11. The heddle of claim 1 wherein at least one of the at least two end-loops ( 17 ) includes a portion ( 15 , 16 ) free of joins ( 13 , 14 ).

12. The heddle of claim 11 wherein the portion ( 15 , 16 ), which is free of joins ( 13 , 14 ), has a length B that corresponds to at least a quarter of a distance between the thread eye ( 8 ) and the portion's respective end loop ( 17 ).

13. The heddle of claim 1 wherein at least two of the at least two bands ( 2 , 3 ) extend into an end-loop ( 17 ) portion, and
wherein, in the end-loop portion, the at least two of the at least two bands ( 2 , 3 ) are not superposed.

14. Method for the manufacture of a heddle, the method comprising:
bringing together of two bands ( 2 , 3 ), flat side to flat side, and making at least two joins ( 13 , 14 ) which connect the two bands ( 2 , 3 ) at least in sections of their surface area,
creating a space between the two bands—between the at least two joins ( 13 , 14 )—of their extension in the heddle's longitudinal direction (L),
inserting at least one component ( 6 , 7 ), which limits a thread eye ( 8 ), in the space.

15. The method of claim 14 further comprising before bringing together the two bands ( 2 , 3 ), making notches, raised impressions ( 5 ) and/or recesses ( 11 , 12 ).
