Document Type and Number:
Japanese Patent JP4621310
Kind Code:
B2
Abstract:
The present invention concerns a pulling clamp for rapier looms with a plunger (6) movable longitudinally in the body (1) of the clamp and pushing an elastic tongue (10) against the gripping surface (12) of the hook (5) of the clamp. The invention is characterized in that the elastic tongue (10) is solidly fastened to the body (1) of the clamp and thus performs, in its thread gripping motion, only movements at right angles relative to the gripping surface (12) of the hook (5). Other than in the pulling clamps according to the state of the art, in which the elastic tongue is fastened to the plunger and thus performs during the thread gripping motion also a longitudinal movement relative to the hook, the present invention presents the advantage that any dragging of the elastic tongue (10) against the fibrils to be gripped, as the thread is gripped with a movement at right angles relative to its fibrils only, in such a manner that an important cause of fibril rupture at the moment of the gripping action is eliminated. The inventive clamp is particularly useful if applied on rapier looms for processing threads composed of very delicate fibrils such as glass fibrils especially if such threads are low twist or twistless threads.
