Abstract

The present invention provides an actuator (10) for a shed-forming device for a weaving machine, the actuator (10) being arrangeable for moving at least one warp thread (1), the actuator (10) comprising an artificial muscle (11) having an input for receiving an actuation signal (12), the configuration of the artificial muscle (11) being variable in response to the actuation signal (12) in order to move the at least one warp thread (1). The use of an artificial muscle (11) as an actuator (10) has the benefit of a fast response when a change in configuration is required, reduced power requirements when compared to conventional actuators based on electric motors, compactness, robustness, reduced noise during operation and reduced cost to manufacture.

Description

technical field [0001] The invention relates to an actuator for a shedding device of a weaving machine, a shedding device, a weaving machine comprising the actuator and a method of operating the actuator. Background technique [0002] Looms based on the Jacquard shedding mechanism have been in use for over two hundred years, allowing materials to be woven into intricate patterns. In such looms, the warp threads are moved to form a shed into which the weft threads can be inserted. Each warp is raised or lowered according to the desired pattern. The Jacquard mechanism includes an actuating device placed above the loom and connecting the actuating device to harnesses that extend over individual warp threads on the loom. The harness comprises a series of healds controlled by an actuating device. Each heald controls one or more healds and is guided within the target board. Eyelets are formed in each heddle to receive warp threads. Conventional actuating devices employ recipr...
