ABSTRACT:
Jacquard machine with lifter device has a first (1) and a second lifter element (2). The lifter elements are suspended from at least one hook (3, 4), (5, 6) respectively, which hook can be selected to be carried along by one of two knives (7'), (8') moving up and down in counterphase. A reversing roller (9') is provided. A lifter cord (10) is attached by one end (10') to a part of the device and is passed in succession over a roller (1') of the first lifter element (1), the reversing roller (9') and a roller (2') of the second lifter element (2). The other end of the cord is connected to one or more harness cords for lifting at least one warp thread on a weaving loom. First and second grates are provided on the machine. The reversing roller (9') is attached on a first grate (12). Each grate (12), (11) optionally can be disposed either in a fixed position or in a movable position such that it can be set in motion up and down in phase with one of the knives (7'), (8'). The Jacquard machine is convertable from a three-position Jacquard machine to a four-position Jacquard machine, and vice-versa, or to a five-position Jacquard machine, and vice-versa.
