A knife construction for a double-lift open-shed Jacquard loom includes two knife boxes which are movable in opposite directions past each other. The knives of each knife box consist of a carrier member having hook plates fastened thereto and provided with spaced control hooks. Lifter members formed as flat bars controlled by main needles arranged transverse to the knives each include two main noses engageable with the control hooks of the movable knives and a holding-up nose engageable with a stationary upper-shed knife. The formation of the control hooks and the main noses in the control direction of the main needles permits movement of the lifters intermediate the control hooks of a knife. In order to furnish a simplified and stable knife construction in which the hook plates and their control hooks can be manufactured as stamped parts and replaceably fastened to the carrier part it is proposed that the control hooks (18) of a knife (1) be formed at the vertical edges of a plurality of hook plates (3), and that each hook plate (3) has between its control hooks (18) a longitudinal slot (8), offset from the middle longitudinal plane, which can be shifted in the direction of control of the main needles (15). The individual hook plates (3) are positioned with uniform indexing on the carrier part (2) of the knife (1).

Knife construction for a double-lift open-shed Jacquard loom

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.
