Double lift, open shed Jacquard loom

Abstract

A double lift, open shed Jacquard loom comprises a Jacquard prism and a plurality of hooks controlled by suitable control needles. The leg of each hook contains three hook noses that are engageable with upper and lower sets of opposed, parallel knives. The sets of knives are movable toward and away from each other by a crank or camming mechanism. The hook noses are also engageable with a stationary set of arresting knives. The hook are guided and maintained separated from each other by upper and lower stationary rakes, and the upper set of knives is located above the upper rake. In order to reduce friction between the hooks and rakes caused by sliding contact therebetween, lifting of the hooks by the upper set of knives is vertically guided along a curved path, and lifting by the lower set of knives is vertically guided along a straight line path. As a result, the hooks are urged sideways only above the upper rake; friction is reduced because the hooks are not pressed sideways against the rakes during lifting.
