Description

[0016] At a supply device, a complementary first holding element and/or at least one complementary further holding element may be displaced in a direction parallel to a common axis by a detensioner element, thereby enabling a weaving accessory to be picked up.

[0017] FIG. 1 shows a symbolic oblique view of essential components of the device according to the invention.

[0018] FIG. 2 shows a symbolic side view of a carrier means for a first or further holding element.

[0019] FIG. 3 shows a symbolic side view of a carrier means for a complementary first or complementary further holding element.

[0020] FIG. 1 shows a symbolic oblique view of essential components of the device 1 according to the invention. Along the common axis 18, two holding elements 2 and 3 are shown in an upper area of the device 1 and two holding elements 13 and 14 are shown in a lower area of the device 1. The holding elements 2, 3, 13 and 14 are provided for transport non-portrayed weaving accessories from a supply device 4 on the left in the drawing to a receiving device 5 on the right in the drawing. The supply device 4 shown in the drawing comprises two upper components 41 and 42, which are shown as rails, and two lower components or rails 43 and 44, on which weaving accessories may be positioned in readiness and picked up by the holding elements 2, 3, 13 and 14. The receiving device 5 shown in the drawing comprises two components or rails 51 and 52 in the upper area and two rails 53 and 54 in the lower area, onto which the drawn-in weaving accessories can be transferred. In all conceivable embodiments, both the supply device 4 and the receiving device 5 can have, independently of each other, a different number of rails or components in general, whose number can range from 1 up to 24, for example.

[0021] The first holding element 2 is arranged at a carrier means 6. The second holding element 3 is arranged at a carrier means 7. The complementary first holding element 13 is arranged at a carrier means 15. The complementary further holding element 14 is arranged at a carrier means 16. The carrier means 6, 7, 15 and 16 are arranged rotatably around the common axis 18. The first holding element 2 and the complementary first holding element 13 can transport a pretensioned heald at its end loops from the supply device 4 to the receiving device 5. Similarly, the further holding element 3 and the complementary further holding element 14 can transport a pretensioned heald at its end loops from the supply device 4 to the receiving device 5. For this purpose, the holding elements 13 and 14 are attached pivotable to the carrier means 15 and 16, as is indicated by the bearing axis 21. In order to detension the healds, the holding elements 13 and 14 can be moved upwards, as per the drawing, with the detensioner elements 20. The detensioner element 20 shown on the right in the drawing is configured integrally with a releaser element 12. In this way, a tension-free heald can be transferred by the push-off element 9 of the carrier means 7 and 16 onto a rail 52 and 54 of the receiving device. The push-off elements 9 are shown appropriately in the extracted state. The push-off elements 8 are shown in the tensioned state. In the embodiment shown, the carrier means 7 and 16 first of all rotate from the rails 52 and 54 further to the rails 51 and 53. The carrier means 7 and 16 then pass the stationary device elements 10, which come into engagement with the pretensioning elements 19 and thereby convert the push-off elements from the extracted state (shown as push-off elements 9) into the tensioned state (shown as push-off elements 8), as shown in the case of the carrier means 6 and 15.

[0022] The releaser elements 12 interact with release elements 11 in order to unlock the push-off elements 8 and thus to convert them from the tensioned state (shown as push-off elements 8) into the extracted state (shown as push-off elements 9). For this purpose, the releaser elements 12 perform a movement parallel to the common axis 18. Two release elements 11 are shown for each carrier means 6, 7, 15 and 16. In other embodiments, the carrier means 6, 7, 15 and 16 may only have one release element 11.

[0023] FIG. 2 shows a symbolic side view of a carrier means 6 or 7 for a first or further holding element 2 or 3. In this enlarged view, the pencil-shaped configuration of the holding element 2 or 3 is more easily recognizable. The push-off element 8 is shown in the tensioned state.

[0024] FIG. 3 shows a symbolic side view of a carrier means 15 or 16 for a complementary first holding element 13 or complementary further holding element 14. Compared to FIG. 2, the carrier means 15 or 16 shown here comprises a bearing axis 21 for the movable arrangement of holding elements 13 and 14. In addition, the drawing shows an optional detensioning pressure element 17. Accordingly, the detensioner element 20 does not press directly on the pivotable holding element.
