Three-position-jacquard machine

Abstract

A three-position shed-forming device with a shed-forming element (10);(60,70) in connection with a warp yarn, two lifting devices (1),(2);(41),(42);(51),(52) with a different lifting height (h), (2h) which are movable up and down in phase, and a selection device (20,21); (83,84) (93,94) in order to have the shed-forming element carried along either by the first lifting devices (1);(41);(51) or by the second lifting devices (2);(42);(52) or by none of the lifting devices. A similar device is able to bring, during successive weft insert cycles, a warp yarn alternately into the lower position and in any of the upper, center and lower positions, and has no pulley block elements. A device comprising two shed-forming element (60),(70), both, as described above, working together with a respective set of two lifting devices movable in phase (1),(2); (41),(42); (51),(52) with different lifting heights (h), (2h) while the lifting devices of the different sets are movable in opposition, and a pulley block element (103) transmitting the movements of the two shed-forming elements to a warp yarn, is a compact three-position shed-forming device with one pulley block element (103).
