Shed-forming device for two-position open shed weaving machines

摘要

A shed-forming device for individually controlling heddles for warp threads of a weaving device has hook elements connected to the heddles for the warp threads. Upward and downward moving knives are provided to which the hook elements can hook onto. The hook elements are provided with spring elements and actuators connected to the spring elements allow the hook elements to selectively hook or not hook onto the upward and downward moving knives. Each hook element also has at least three spring elements in the form of spring legs. At least two spring elements are made as double laminated springs. At least two of the spring legs are provided with hooks for working together with the moving knives. One or more actuators are provided which selectively influence the various spring elements. Retaining hooks are provided for at least a part of the spring elements in a position determined by an actuator.
