ABSTRACT
The weaving process involves preparation of warp and weft yarns. The weft yarns that comes directly from spinning is used as it is, but sometimes they are rewound in small bobbins on winding machine to produce a larger weft yarn package. In practice, the weaving machines are named after their weft insertion systems. Mainly, there are two main weft insertion systems, namely shuttle weft insertion and shuttleless weft insertion systems. The motions that are compulsory for weaving process are called primary motions. Weaving will not happen if any of these motions are not completed. The closed shedding system employs all of the warp yarn levels after the insertion of each pick. The level is made either at bottom/top or at the center of shed line. In open shedding, the warp is only moved when a pattern requires a change of position. Weft stop motion has been used to stop the loom at the event of weft breakage.
