ABSTRACT:
A shed-forming device for a textile machine which includes lift blades (e.g., 3) arranged to hookingly engage or slidably contact an associated hooking engagement element (e.g., 4) such that the hooking engagement element is either lifted into an upper shed position to effect a shed change or alternatively, is pivoted into an arrested lower shed position by the attractive force of an associated electromagnet (e.g., 5). The hooking engagement elements are arranged in pairs by flexible connecting elements (e.g., 9) which form a loop into which is disposed a roller (e.g., 12) operatively attached to a shed such as a harness (e.g., 13). A pulling force generated by the movement of the roller and harness serves to pivot or position the hooking engagement element for cooperation with the lift blades and accordingly, facilitates changing of the harness.
