Abstract: The weaving machine comprises a reed and a cutting mechanism which is associated with the cloth edge on the picking side and which has a cutting element lowerable at the picking cadence from a neutral normal position above an imaginary prolongation of the beating-up line into a second operative position which is disposed approximately at the height of the beating-up line at a lateral distance from the movement zone of the reed and which is operative to guide the weft yarn to be severed. The cutting element is adjustable through the agency of an additional drive connection to move substantially parallel to the picking direction into a third operative position which is closer to the cloth edge laterally and which is disposed in the movement zone of the reed. In the third operative position, a second cutting element cooperates with the first cutting element to sever the weft yarn from the weft yarn supply at a very reduced distance from the cloth edge.

Abstract: The present invention relates to a weft insertion device for use on a band-gripper weaving machine. The device has a driven, rotationally oscillating band wheel having a flexible insertion band including a gripper head. The band executes an oscillating movement transversely to the warp shed as the band unwinds from the winds onto the circumference of the band wheel. The circumference of the band wheel is smaller than the maximum excursion of the gripper head. The insertion band is wound around the circumference of the band wheel to the extent of more than 360.degree. when the gripper head is in the position in which the head is fully and maximally withdrawn from the warp shed. In this way, the diameter of the band wheel can be kept small. This small diameter permits operation at high rotational speeds and also renders the band wheel less expensive. This is particularly advantageous when the machine is wide. Further, the contribution to total machine width made by the band wheels is less than under the prior art, and additionally the height of the machine does not need to be increased with a corresponding increase in machine width.
