At Novosibirsk State Technical University NETI, a fully domestic accelerator for the "SIGOTEC" weaving loom has been created, which will help improve the quality of fabrics and the productivity of looms. According to the university's press service, the device has already passed laboratory tests and is now preparing for production tests on various models of weaving looms.
The weft yarn laying accelerator of the weaving loom is a device that works like a piston engine and is controlled by signals from other parts of the loom, such as an encoder [a device that determines the angle of rotation of a rotating object]. During development, we moved away from the original idea, which was structurally disadvantageous in terms of technical performance, in favor of the concept of a crank mechanism. The market offers accelerators whose principle is based on the deformation of the launching body and the storage of potential energy, which is released at the moment the needle is launched. Most accelerators do not have a return mechanism that allows the process to be continuous. The accelerator we have developed provides the possibility of continuous operation of the device, as well as control of the speed and position of the needle.
Among the advantages of "SIGOTEC" are its cost, which is 30-35 percent less than that of analogues, its productivity is 40% higher than that of similar devices, and its complete import independence. The accelerator is assembled from fully domestic parts and has Russian software that adapts to different types of weaving looms.
