BASIC MOTIONS IN WEAVING

Every loom requires three primary motion to produce woven fabric.

Shedding

This process refers to separate the warp threads into two layers. One layer is raised and other lowered.

Picking

This process refers to insert a weft thread across the warpends through the shed.

Beat-up

This process referes to push the weft thread that has been inserted across the warp ends upto the cloth fell. Besides the three main basic motions in weaving, there are other two subsidiary motions necessary for continuous weaving which are termed as secondary motion.

Take Up

This is the motion to pull the cloth forward after the beat-up of weft, maintaining the same pick density and spacing throughout weaving of a cloth and winding the woven cloth on to a roller.

Let-off

This motion allow the warp to unwind from the warp beam during weaving and also maintain an average constant tension of warp as it weaves down. In order to produce a good quality of cloth and to prevent damages, it is necessary to have some stop motions provided on the loom. which are termed as auxiliary motions.

Warp Protector

This motion protect the warp threads by stopping the loom when the shuttle fails to reach, the selvedge side and box properly into either the shuttle box during picking.

Warp Stop

This auxiling motion to able to stop the loom when a warp thread breaks or get excessively loosened.

Weft Stop

This motion able to stop the loom when a weft breaks or the weft runs out of the pirn (weft package).

Temple

This motion holds the cloth firmly at the fell to assist the formation of a uniform width cloth.
