The rapier loom is the most commonly used type of shuttle-less weaving machinery. Its primary features include fast weaving speed, high level of automation, and maximum efficiency. In addition to the said characteristics which are inherited from previous shuttle-less weaving machine designs, the rapier loom also has its own advantage over them. For instance, its positive weft insertion mechanism is suitable for weaving a variety of fiber yarns. Moreover, the unique weft color selection system allows for a maximum of 16 colors of filing picks to be woven. With all those matchless features available at a low price, the loom has seen wide use in weaving dyed yarn, towel, silk weave, wool fabric, and bast fabric. It also provides ideal solutions for small batch production of fancy cloths.
Over the past few years of development, the rapier loom has grown into one of the most commonly used types of weaving machines. Thanks to the application of advanced technology as well as weaving process innovation, the loom will continue to evolve as it improves its weaving performance.
Increasing weaving speed has always been one of the goals that loom designers pursue. Based on the CAD andCAMtechniques, we have worked out the optimized designs for each part of the loom (especially the weft beating-up mechanism and weft insertion system) as well as the integrated loom as a whole. As its weft insertion rate is further improved, the rapier loom can be on a par with the air jet loom.
High speed does not necessarily mean high efficiency. A high efficient terry loom means that the machine is capable of yielding quality fabrics without defects at high operating speeds. To become truly efficient, our terry loom introduces microelectronics technologies, along with the microprocessor and electronic computer. The electronic yarn cleaner, for example, can detect the yarn defects and remove them in time. By plugging the yarn cleaner into the port of microprocessor, users can get the statistical classification of yarn defects, thick spots (slub), and thin spots. The fabric inspection machine is also equipped with a microprocessor, to display in table forms the defective spot counts, defective spot location, length per roll of cloth(removing the damaged part of the cloth), and cloth weight.
Clumsy handling or parts wear during the weaving operation can sometimes lead to loom damage. One of the typical symptoms involved in loom damage is slow loom start-up which results in decreased weaving efficiency. Among many types of loom damages, the most common one is the faulty brake. Therefore, be sure to check the loom brake on a regular basis.
1. Loom parts and component quality issues
2. Loom matched parts problems
3. Electrical control system or electrical element problems
4. Bought-in components fault
5. Problems occurring in the process of final assembly
Check if the ring seat of the temple rotates flexibly or there is any abrasive wear occurring to the said ring. Inspectors also have to make sure there is no air hose leak, the centralized lubrication system does not leak, and the oil pump is not damaged or bent. The flying fibers which might have been piled up inside the control box should be removed. The height error of the heald frame should be restricted within a range of ±2mm. Other check points that users need to watch out for include the oil filter screen, warp let-off shaft, wire insulation and coating, brake clearance, gear surface, and heald frame.
The shuttle-less can be further classified into the following types: gripper loom, water jet loom, air jet loom, and rapier loom. Among them, the gripper loom consumes the least amount of unit energy, which is followed by the water jet loom. The air jet loom and rapier loom are two weaving machines that consume a large amount of energy. While it is true that energy consumption is not the only factor which influences consumer behavior, there is equally no denying that energy efficiency is a key point that no one can overlook. For this reason, the textile machinery manufacturer must give due consideration to developing energy efficient technologies.
