DEVICE AND METHOD FOR EXTRACTING WEFTS IN A REINFORCING PLY INTENDED FOR THE MANUFACTURE OF A TIRE

摘要

Device intended for extracting weft threads (T) arranged transversely in a straight grain reinforcing ply (F) comprising a hook capable of gripping a weft thread (T) by performing an alternating movement between a high position and a low position, characterized in that the hook engages with a disengageable anvil capable of moving along the path (XX′) of the hook so that when the device is in operation, the anvil is engaged in contact with the hook during all or part of the descending movement of said hook, forming a clamp capable of holding a section of weft between the hook and the anvil the anvil is disengaged from contact with said hook during the remainder of the travel of the hook, so as to enable the hook to engage a weft thread (T) and to release a section of weft (T).

1) A device intended for extracting weft threads (T) arranged transversely in a ply made of straight-thread reinforcing threads (F) comprising:
a hook capable of gripping a weft thread (T) by performing an alternating movement between a high position and a low position, a disengageable anvil capable of moving along a path (XX′) of the hook so that, when the device is in operation,
the anvil is engaged in contact with the hook during all or part of the descending movement of said hook, thereby forming a clamp capable of holding a section of weft between the hook and the anvil, andthe anvil is disengaged from contact with said hook during the remainder of the travel of the hook, whereby the hook is able to engage a weft thread (T) and to release a section of weft (T′).
