Abstract
Device comprising a structure disposed above the knives of an electronically controlled Jacquard machine such that on the upward movement of the knives the hooks moving with them carry along at least one part of the structure. As a result, during the dropping of the knives the downward retracting force acting upon thw hooks is increased by the weight carried along. A preferred embodiment is an auxiliary grid comprising a number of horizontal auxiliary grid bars fixed parallel and adjacent to each other in a frame. Each of said bars lie parallel along the direction of movement of a knife and just above it, in such a way that a hook moving up with the knife raises the grid with its hook nose. The grid is supported and guided by various mechanisms.
