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.
