ABSTRACT:
A double-lift open-shed jacquard machine with two lifting bars which are movable in opposite directions to each other and which pass each other, and with lifters controllable by main needles, the latter being arranged transverse to the knives of the lifting bars, which lifters have two main projections associated with the movable knives and one holding-up projection associated with a fixed upper-shed knife. The movable knives are made of a carrier part and hook plates fastened thereto with control hooks, the latter being bent off in the direction towards the main projections of the lifters and being arranged spaced apart from each other. The shaping of the hook plates and their control hooks permits in the control direction of the main needles a passage of the lifters up into a plane lying between the control hooks of a knife, and the shank of the lifters has a flat rectangular cross-section, whose greater bending moment lies in the control direction of the main needles.
