ABSTRACT:
A weft thread shuttle for travelling-wave shedding looms, wherein the shuttle is moved in a shed independently of the beating-up mechanism. This shuttle has a bevel tip, a spool with the weft thread and means for tensioning the thread laid-in in the shed facing the beating-up mechanism for beating it up to the fell of fabric. The side wall of the shuttle facing the beating-up mechanism is arranged at an acute angle to an imaginary line extending in parallel with the direction of movement of the shuttle in the shed, and is smoothly conjugated with the surface of the tip and has a height gradually increasing from the tip to the rear wall of the shuttle. This construction of the shuttle permits to eliminate the appearing looping without stopping the loom.
