The yarn from the pirns is converted into cheeses/cones in winding department by using winding machines like autoconer and there is pattern breaking mechanism to prevent slough off(layers of yarns comng out). after winding the yarns are taken to warping machines where the yarns are taken from various cheeses and cones and placed on a stand called creel and wound in parallel fashion. then the warpers beam is passed through sizing paste where the size is applied containing tapioca starch and gawar gum and the sized yarns are made stronger. then the sized beam is taken to the loom where the process is called beam making and the beam gaiting is done where the beam is tied by knots and kept at the back of the loom where the fabric is woven. the threads along the longitudinal section of the cloth are called warp and the threads through across the width of the cloth are called weft. the threads per inch are calculated putting pick glass on the fabric and warp threads are called picks per inch. in case of weaving we have various machines such as airjet, projectile, multiphase, multiaxial, water jet, needle weaving, weaving + embroidery, and rapier looms. In rapier weaving we have flexible as well as rigid rapier. also we have single and double rapier. in looms we have automated looms and nonautomatic looms, shuttless looms and shuttle looms. in looms we have loose reed as well as fast reed . in loose reed we have shuttle after getting trapped in the middle of the loom the reed goes backward. in case of fast reed the reed does not go backward. then we have under pick over pick looms. underpick means the picking is done below the loom i mean picking stick is below the loom and over[pick means the picking stickl mounted above the loom. then we haveweft stop motion that is center weft fork motion and side weft fork motion. in center weft fork motion the mechanism is placed at the center of the loom and side weft fork motion means the mechanism is placed at the side of the loom. then there are drop wires where the warp breakage causes stoppage in the loom. In case of air jet loom the weft thread is thrown across the width of the loom using air jet. in case of water jet loom the weft is thrown across the loom using water jet. in multiphase we have small small sheds formed where the shuttle traverses across the width of the loom. in needle weaving smalll width fabric is formed. in rapier a swaord is used where the weft is attcjhed to throw it across the width of the fabrics. shuttle looms are those looms where shuttle is used and shuttleless looms are those looms where shuttles are not used but some other mechanism i used
