Abstract: A device for use with a Jacquard machine is disclosed which may eliminate the pattern cards, may be made compact in size, may find a wide application, and may considerably increase the weaving speed. In opposed relation with a plurality of needles is disposed a selection mechanism in which a plurality of solenoids equal in number to the needles are disposed in opposed relation with a plurality of armature members equal in number to the needles and interconnected therewith through wires. A control unit is adapted to selectively energize the solenoids depending upon the desired fabric patterns while the armature members are moved toward and made into contact with the solenoids in synchronism with the weaving operation of the power loom so that the selectively energized solenoids attract the armature members to hold their corresponding needles in position while the remaining needles corresponding to the de-energized solenoids are returned to their initial positions. The hooks corresponding to the needles returned to the initial positions are made into engagement with their corresponding knives in a knife box so that when the knife box is lifted, they are also lifted to lift the desired warp yarns, thereby forming a desired shed.
