Weft thread gripping mechanism for a loom with a travelling-wave shed and a disk-type beat-up motion

摘要

The proposed weft-thread gripping mechanism includes gripping members elastically tightened together and installed at the side of exit of weft thread carriers from a travelling-wave shed. The gripping members, one of which is movable relative to the other one, are mounted on a shaft of a disk-type beat-up motion so as to be rotatable therewith and displaceable, after gripping the weft thread, lengthwise the shaft axis in the direction from the travelling-wave shed. Located on the shaft of the disk-type beat-up motion is a stationary stop cooperating with the movable gripping member at the moment of the closest approach of the gripping members to the travelling-wave shed for a gap to be formed therebetween a weft thread passes through. This makes it possible to keep taut the weft thread advanced to the fell of the cloth till the end of the process of the cloth formation.
