A device for forming a leno selvedge has two lifter seats and a metallic approximately U-shaped half heddle with two legs, which are connected by a web, wherein each lifting heddle has a lifting heddle foot having an opening extending in the longitudinal direction of the heddle, wherein the lifting heddle foot at least on one side of the slot at least one magnet, with which the one leg of the half heddle cooperates, wherein the opening extends over the entire height of the heddle foot continuously.

Claims

1. An apparatus for forming a leno selvage, comprising: two lifting heddles; and one metallic half-heddle of approximately a U shape and having two limbs that are connected by a web, wherein each lifting heddle has a lifting heddle foot that has an opening that extends in the longitudinal direction of the lifting heddle, and wherein the lifting heddle foot has at least one magnet at at least one side of the slit, said at least one magnet cooperating with the one limb of the half-heddle, wherein said opening extends continuously over the total height of the lifting heddle foot.

2. An apparatus in accordance with claim 1, wherein said opening is configured as a slit.

3. An apparatus in accordance with claim 1, wherein the limb of the half-heddle has a stopper for contacting the lifting heddle foot.

4. An apparatus in accordance with claim 3, wherein the stopper is arranged at the limb of the half-heddle such that the lower end of the limb of the half-heddle that projects over the stopper projects up to and into the effective region of the at least one magnet in the lifting heddle foot.

5. An apparatus in accordance with claim 1, wherein the lifting heddle foot is set out laterally to form an abutment for the stopper.

6. An apparatus in accordance with claim 1, wherein the limb of the half-heddle is set out laterally to form a half-heddle foot.

7. An apparatus in accordance with claim 6, wherein the half-heddle foot has the stopper.

8. An apparatus in accordance with claim 1, wherein the half-heddle foot cooperates with the at least one magnet in the lifting heddle foot.

9. An apparatus in accordance with claim 1, wherein the lifting heddle has two limbs, with the one limb of the lifting heddle having a guide groove for the one limb of the half-heddle.

10. An apparatus in accordance with claim 9, wherein the lifting heddle has a saddle for contact with the web of the half-heddle in the transition region of the limbs of the lifting heddle.

DETAILED DESCRIPTION OF THE INVENTION

(7) The apparatus for forming a leno selvage (leno weave apparatus) has the reference numeral 1. The leno weave apparatus comprises the two lifting heddles 5 and the half-heddle marked by 20. Each lifting heddle 5 has a first limb 6 and a second limb 7 that are connected to one another approximately centrally (arrow 8) in the region of the saddle 9. A holder 10 is provided in the first upper limb 6 and has an opening 10a that serves the connection to, for example, a heddle carrier rail at the loom. The second lower limb 7 has the lifting heddle foot 11 that likewise has an opening 11a for equally receiving a heddle carrier rail.

(8) The further configuration of the second lower limb 7 is now relevant that has, starting at the center region (arrow 8) a guide groove 7a in the region of the saddle 9 for guiding the limbs 21 of the half-heddle 20. The lower limb 7 is provided with the lifting heddle foot 11 at the lower end. The lifting heddle foot 11 has a slit 13 that extends from the upper end to the lower end through the lifting heddle foot 11. The opening 11a has been omitted for better clarity. A respective magnet 14 that cooperates with the half-heddle foot 23 of the half-heddle 20 in accordance with FIG. 3 is provided at both sides of the slit. The magnets 14 are directly opposite one another. The slit 13 in the region of the lifting heddle foot 11 forms the prolongation of the guide groove 7a in the second lower limb 7 of the lifting heddle 5. It is essential in the embodiment of the lifting heddle foot 11 that the slit 13 as a prolongation of the guide groove 7a is continuous to, for example, remove dust building up in the slit 13 from above, and optionally also from the side using a blade (arrow 28), with it having to be mentioned that the leno weave apparatus here does not have to be deinstalled from the loom.

(9) The design of the half-heddle 20 results from a view in FIG. 3 and FIG. 5.

(10) As already explained at another passage, the half-heddle 20 is formed in approximately a U shape in a plan view, with the limbs 21 of the half-heddle being connected by the web 21a in the upper region. The eye 24 for the standing thread (not shown) is located above the web 21a. The half-heddle 20 lies on the saddle 9 of the lifting heddle 5 by this web, and indeed whenever the lifting heddle 5 is in the upward movement. The leno thread (not shown) is in this case located between the other, oppositely disposed lifting heddle and the corresponding limb of the half-heddle. In this state, the half-heddle 20 is held by the magnets 14 in the lifting heddle foot 11 of the upwardly moving lifting heddle. To now prevent the half-heddle foot 23 of the half-heddle from slipping through the slit 13 in the lifting heddle foot 11 at high weft speeds and with a worn saddle, the half-heddle foot 23 has a stopper 25 that is held by the abutment 17 of the lifting heddle foot 11. The abutment 17 is formed by an upper edge of the lifting heddle foot 11 that is horizontal in the installed state. Provision is made here that the stopper is arranged at the limb of the half-heddle such that the projecting end of the limb 21 of the half-heddle 20, the lower end in the installed state, projects up to and into the effective region of the at least one magnet 14, advantageously of the two mutually opposite magnets, into the lifting heddle foot. It is thus ensured when the stopper 25 lies on the abutment 17 of the lifting heddle foot that the half-heddle foot 23 is in contact with the magnet or magnets 14.
