Constant vigilance of men, machines, materials and atmospheric conditions is required for smooth and efficient working of a loom shed. Though the checkpoints are already known to the supervisors, they must be conscious of these aspects while patrolling the department. The followings are details of the checklist:
The quality control function is required to monitor the qualitative performance of the incoming material, in-process material and the finished product. This involves conducting of studies/tests, both routine and special. Routine Studies End Breaks and Operations Warp and weft breakage studies should be conducted once a month for each count. The breaks should be noted[…]
Weaving is done on a machine called a loom. All the weaves that are known today have been made for thousands of years. The precise shape of the loom and its mechanics may vary, but the basic function is the same. Warp yarns are held taut within the loom, and weft yarns are inserted and[…]
Water Jet Loom An effort to achieve: Weaving machine makers produced gripper shuttle and rapier machines belonging to second generation of shuttle loom. But in both machines, something solid enters shed and yarn is suddenly accelerated to very high velocity-stretching tender yarns undesirably. Then third generation of Air Jet and Water Jet looms when fibre spun as well[…]
Weft Storage System – Drum Feeder The following figure shows the schematic diagram of a drum feeder for air-jet weaving machines. The weft yarn is drawn off the package and wound onto measuring band two by the rotating motion of yarn guiding tube 1. The pick length depends on the fabric width. The pick length[…]
Working Principle of Air Jet Loom Air jet weaving machines were invented in Czechoslovakia and later refined by the Swiss, Dutch, and Japanese were designed to retain the tension less aspect of the picking action of the water jet while eliminating the problems caused by the use of water. The yarn is pulled from the supply package[…]
