Weft cutting device in looms with mechanisms for multi weft weaving

摘要

There is disclosed a device for cutting weft in looms with mechanisms for multi-weft weaving. The cutting device includes a holder on which mutually adjustable shields are mounted. The shields are provided with entrapping dents for the introduction and location of weft between the blades of cutting jaws at a cutting point. The cutting device has a movable jaw which is adjustably connected to a control lever. Adjustable shields and cutting jaws permit the use of the entire length of knife blades secured to the jaws. In this manner, during cutting the overlap is minimized and the lifetimes of the cutting edges and the cutting jaws are increased.
