DEVELOPMENT OF THE DOUBLE THREAD CHAIN STICH SEWING MACHINE WITH REVERSE MOVEMENT

In the work, we propose the algorithm of modernization of a specific chain stitch sewing machine, as a result of which significant expansion of technological possibilities of this machine is possible. In this work, the essence of the problem solved through the modernization, the composition and structure of devices, which need to be mounted in the machine, and their connection with the existing mechanisms of the machine, are developed. In addition, we provide the calculation of the main dimensional parameters of devices that provide reliable operation of the machine in both modes, as well as the trouble-free transition from one mode to another.
