Abstract
A shedding selection device for Jacquard-type weaving- and knitting machines can simply make use of bimorf or piezo-electric bending elements (9), under the condition that the complementary hooks (2,12) are resilient hooks which are resiliently mounted on one of the ascending- and descending parts of the shedding devices. Additionally the selection of shedding devices can be realized with only one such bending element (9) per harness cord (25).
Claims13
Shedding selection device in a Jacquard-type weaving and/or knitting machine comprising:
- up- and downwardly complementary moving hooks (2,12.) interconnected by one and the same cord,
- a bending element (9) which is adapted to be clamped on one end to a frame of the weaving and/or knitting machine, said bending element being provided with electrical terminals for connection to an electric power supply, said bending element having a free extremity which moves sideways between a locking position in which clamping of a complementary hook (2,12) by an upwardly moving knife (1,11) is prevented and a release position in which the clamping of a complementary hook (2,12) is possible because detention pin means (8,18) slides away from a track of a suspension hook (6,16) of the respective complementary hook (2,12),
- wherein each suspension hook (6,16) is resiliently mounted by means of a resilient drawback spring (3,13) on said complementary up- and downwardly moving hooks.
