Abstract
A method for treating a weft yarn upon stoppage of a shuttleless loom comprising: stopping a shuttleless loom based on a stop signal; bringing the warp yarns in an open shed condition between the time of switching off said shuttleless loom and the time of restarting said shuttleless loom, so that a weft yarn which has been picked just before the stoppage of said shuttleless loom is released from its crossed condition by said warp yarns; automatically inserting a pushing out device into a clearance between said weft yarn and a preceding weft yarn to separate said weft yarn from a cloth; and removing said separated weft yarn.

A method for treating a weft yarn in a cloth upon stoppage of a shuttleless loom comprising:
- stopping said shuttleless loom based on a stop signal;
- bringing the warp yarns in an open shed condition between the time of switching off said shuttleless loom and the time of restarting said shuttleless loom, so that a weft yarn which has been picked just before the stoppage of said shuttleless loom is released from its crossed condition between said warp yarns;
- automatically inserting a pushing out device into a clearance between said weft yarn and the preceding weft yarn to separate said weft yarn from the cloth;
- and
- removing said separated weft yarn.
A device for separating a weft yarn in the fell of a cloth upon stoppage of a shuttleless loom in which the cloth is being woven, comprising:
- a beam member extending along the cloth width;
- and
- at least one pushing out device attached to said beam member;
- said pushing out device being movable in the lengthwise direction of said cloth from a position spaced away from said cloth to a position within said fell of the cloth between the last picked weft yarn and said cloth for separating said weft yarn from said cloth.
