Abstract
Drive system for the knife grids of a double-lift open-shed Jacquard machine, which is mounted entirely above the Jacquard machine, and which comprises a central drive shaft which at both ends drives a set of conjugate cams which imparts motion to two follower levers which lie diametrically opposite each other. These follower levers carry out a to and fro pivoting movement in opposite phase to each other, about a transverse axis of symmetry, in between their arms. With each pair of follower levers two knife suspension bars are connected to said arms by means of drive rods in such a way that they move up and down in vertical, parallel planes in opposite phase to each other. A number of knives are suspended in the weft direction on every two knife suspension bars moving in phase, which are situated on either side of the machine in the warp direction. The lift and the inclination of the knife suspension bars are adjustable.
