Abstract

A loom equipped with a leveling motion incorporated with a cam-operated type shedding motion. The loom is provided with a control unit to control a variety of operations of the loom. Upon stopping of the loom weaving operation in response to a loom stop signal, the control unit judges that a loom stop time required for recovering a failed condition is longer or shorter than a predetermined time in accordance with the type of the loom stop signal which is different depending upon the cause for which the loom weaving operation is stopped. If the result of the judgement is that the loom stop time is longer than the predetermined time, the leveling motion is operated to level warp yarns at the level near a warp line, thereby loosening the tension applied to the warp yarns.

Dependent claims

A loom comprising:

a shedding motion;
a leveling motion incorporated with the shedding motion, for leveling warp yarns, when said leveling motion is operated;
means for generating a plurality of types of loom stop signals to stop a weaving operation of the loom based on different types of predetermined reasons for stopping the loom;
means for operating said leveling motion in response to one of said loom stop signals;
means for judging that a loom stop time is longer or shorter than a predetermined time in accordance with the type of said loom stop signals, said loom stop time being equal to a time duration between a first time at which the loom weaving operation is stopped and a second time at which the loom weaving operation is restarted;
and
means for operating said leveling motion in response to a judgment of said judging means that said loom stop time is longer than said predetermined time.
