INSERTION ELEMENT FOR INSERTING WEFT THREADS ON A LOOM

摘要

A shuttle for inserting a weft thread into a shed of a loom, the shuttle comprising a body of conchoidal shape, having two sidewalls that are connected along a closed edge portion of the body and are open over the remaining portion of the body; retaining means in the interior of said body for retaining a portion of thread of predetermined length in the form of a coil between said walls; and the interior of the body being so shaped that during its operation on the loom the interior is automatically cleaned of particles of fibers and like contaminants; said body defining a path for the removal of said particles and there being no obstruction along this path that inhibits the discharge of said particles therefrom. The portion of thread to be inserted is wound on a coil-forming member and then transferred to the shuttle by pushing the shuttle over the coil located on the coil-forming member in a direction at right angles to the axis of said member and by moving the shuttle away from the coil-forming member in a direction parallel with the axis of said member.
