bar passes through an axis hole in each hook element 40 thereby providing a common axis for each hook element to pivot the holding bar 10 and axial rod 30 combine to create a no play assembly for the flexure elements 20 this allows the piezoelectric elements to supply all their force and control to the attached hooks 40 each hook element 40 is independently positioned by actuating the piezoelectric in the corresponding flexure element 20 thereby causing the flexure element to bend out of the plane and forcing the connected hook element to pivot about the common axis the present selection device is suitable for use in a jacquard loom used to weave fabric patterns the hook elements may be used to select warp yarns from a harness for lifting to form a shed during weaving this arrangement of flexure elements allows for a selection hook density such that each harness in a loom can be driven independent from one another in a preferred embodiment the array comprises twenty four 24 piezoelectric actuated flexure elements and corresponding hook elements spaced within a length of less than 90 mm these hooks correspond to the yarns in a 24 warp yarn harness this hook density is sufficient for each harness on a loom to be driven independently for control of fewer than 24 yarns the harness is simply not threaded for those yarns conversely to control more than 24 yarns multiple selection cards and harnesses can be used fig2 is a side view.
