Electromagnetically activated jacquard machine with rotating lifting roll

Abstract

A jacquard machine having lifters controlled by electromagnets. Activated by electromagnets are lifters that, according to the weave pattern, must reside in the upper shed. The lifter is arranged between a continuously rotating lifting roll and an appropriately distanced press roller of an anchor of an electromagnet, the roller pressing the lifter to the mantle surface of the lifting roll when the electromagnet is electrically connected according to the weave pattern. Next to each lifting roll, a series of lifters are positioned. The lifting rolls are arranged so that in a vertical plane, along the width of the warp, there exists a roll matrix composed of mutually equal columns of rolls and mutually equal rows of rolls. The one-column lifting rolls together with the respective lifters, electromagnets and the respective mechanical equipment form a roll module, and two roll modules positioned along the warp compose a roll aggregate. The electromagnets are arranged on traverses and connected, by a connector to an electrical connection plate. For each module an assembly for suspending the lifters is prepared. All lifting rolls obtain continuous, unidirectional, uniform rotation independent of the drive of the weaving loom machine, the jacquard machine being interconnected with the weaving loom machine as to the control functions.
