Abstract
Hooks for controlling movement of heddle cords in a Jacquard weaving loom are each displaced by a knife, between a position of top dead center, wherein each hook may be immobilized by a selection device, and a position of bottom dead center. Each hook includes a body provided with a catch that engages a corresponding knife and a metal blade that is relatively movable with respect to portions of the body adjacent the catch and that interacts with the selection device to selectively retain the hook in the top dead position thereof.
