A three-position shed-forming device with a shed-forming element (10);(60,70) in connection with a warp yarn, two lifting means (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 means (1);(41);(51) or by the second lifting means (2);(42);(52) or by none of the lifting means. 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 means movable in phase (1),(2); (41),(42); (51),(52) with different lifting heights (h), (2h) while the lifting means 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).
Three-position shed-forming device, comprising a shed-forming element (10);
Three-position shed-forming device according to anyone of the preceding claims, characterized in that the first (1);(41),(51) and the second lifting means (2);(42),(52) are one above the other during their up and down going movements.
Three-position shed-forming device according to anyone of the preceding claims, characterized in that the lifting height (2h) of the first (1);(41),(51) is almost double the lifting height of the second lifting means (2);(42), (52).
Three-position shed-forming device according to anyone of the preceding claims, characterized in that the selection device (20,21);
Three-position shed-forming device according to anyone of the preceding claims, characterized in that this device comprises a series of shed-forming elements (10);(60), (70) arranged in several rows situated next to each other, in that the selection devices (20,21);
Three-position shed-forming device according to anyone of the preceding claims, characterized in that the selection devices (20,21);
Three-position shed-forming device comprising two shed forming elements (60);(70), a pulley block device (103) provided to transmit the movements of both shed-forming elements to at least one warp yarn on a weaving machine, a set of lifting means with a first (41);(51) and a second lifting means (42);(52) which are movable up and down over a different lifting height (h),(2h) respectively, and a selection device (83,84), (93,94) with which each shed-forming element may be influenced selectively, so that it may be carried along or not by a lifting means of the set, characterized in that for each of the two shed-forming elements (60),(70), a respective set of lifting means (41,42),(51,52) with a first and a second lifting means movable in phase is provided, in that the lifting means of the one set and the lifting means of the other set are mutually movable in opposition, and in that each shed-forming element (60),(70), may also be selectively influenced in order to be carried along either by a first lifting means (41,51), or by a second lifting means (42,52).
