Abstract (en)

[origin: WO9713901A1] The invention concerns a mechanical loom comprising a weaving reed (8) and a weft thread guide device (32) which are interconnected so as to pivot between an insertion position and a stop position. In order to insert the weft, there are provided a stationary weft-insertion device (14) with at least one blower nozzle (22) for inserting a weft thread (38) into the guide duct (36), as well as a thread clamp (16) and scissors (15). The thread clamp (16) is coupled with the weaving reed in order to clamp an inserted weft thread (38) and convey it synchronously with the guide duct (36) from the insertion position to the stop position. The scissors (15) are arranged downstream of the thread clamp (16) in the stop direction in order to cut off the weft thread immediately after it has been clamped. Since the insertion device is stationary and the thread clamp and scissors are operatively associated with the weaving reed, control of the loom is simplified such that up to sixteen different weft threads can be inserted.
