Abstract
Modern tasks of environmentally sustainable development of light industry require continuous improvement of the design of sewing equipment elements. Textile production is one of the key components of the light industry, therefore, innovative developments in the design of sewing equipment elements allow the deployment of green technologies throughout the industry. Moreover, emissions from light industry, as a rule, are easier to reduce precisely from a technological point of view, by improving the design of sewing machine elements and using environmentally friendly textile materials. An analysis of the constructive features of devices for the folding the sewn materials on a sewing machine is given in the article. A constructive scheme and the principle of operation of the improved construction of the ratchet of the device for obtaining various forms of folds of materials are presented. The construction of the folding device with different pitches and shapes of materials on the sewing machine has been recommended. The methods of profiling the curvilinear working areas of the ratchet wheels of the device has been substantiated.
