A shed-forming device for individually controlling heddles for the warp threads of a weaving device has hook elements which are connected to the heddles for the warp threads. Upward and downward moving knives are provided for the hook elements can hook onto. The hook elements have spring elements on a supporting element or carriage. Actuators are provided which influence the spring elements to allow the hook elements to selectively hook or not hook onto the upward and downward moving knives. Each hook element is provided with at least three spring elements in the form of spring legs. At least two spring elements are made as at least double laminated springs. At least two of the spring legs are provided with hooks destined to work together with moving knives. One or more actuators are provided which can selectively influence the various spring elements. Retaining hooks are provided for at least a part of the spring elements in a position influenced by an actuator.
Shed-forming device for individually controlling warp threads of a weaving device comprising heddles for warp threads, hook elements connected to the heddles, upward and downward moving knives to which the hook elements can hook onto, spring elements on the hook elements, actuators for controlling movement of the spring elements and allowing the hook elements to selectively hook or not hook onto the upward and downward moving knives, each hook element having at least two spring elements formed as double laminated springs, at least two of the spring elements having hooks for working together with the knives, at least one actuator on a selector frame of the shed-forming device for selectively influencing the spring elements, and at least one retaining hook for retaining the hook element when one or more spring elements are influenced by an actuator such that the hooks on the spring legs do not hook onto the upward and downward moving knives.
