ABSTRACT:
A shuttleless loom of the type having unidirectional weft thread carriers, comprising a device for throwing at least one said carrier, the device including a guide defining a closed path one portion of which passes through the shed and another returns below the shed. The guide also includes two arcuate portions at opposite sides of the loom and a circular guide portion substantially tangent to the carrier throwing path. Within the circular guide portion there is rotatably arranged a flywheel provided with an entraining member for the carriers. There is further provided a door which is controlled to throw out of the circular guide portion the carriers after they have made at least one complete revolution within the circular guide portion. The carriers are of substantially cylindrical configuration and adapted to accommodate circumferentially the weft thread as positioned at the exit of the circular guide portion in a direction substantially perpendicular to the carrier axis. The device further includes gripping and cutting members for the weft thread located at the exit of the circular guide portion to hold the weft thread engaged on one side by the carrier at least for the whole time during which the carrier is moving through the shed and to cut the weft thread on the other side substantially when the carrier reaches the midpoint of the travel thereof through the shed.
