METHODS OF PROJECTING OF AUTO THREAD CUTTING MECHANISM FOR MULTI-HEAD SEWING SEMI-AUTOMAT WITH MICRO PROCESSOR CONTROL

Abstract

The methods of projecting of automatic thread cutting mechanisms are developed, which include drawing up the initial requirements to projecting of a new mechanism; structure selection; scheme development; calculation of technological parameters of the mechanism; the experimental study of dependence of the force applying to movable cutter on relative thread deformation; the software, calculating the force emerging in the process of thread cutting under the given parameters; the development of requirements for design solutions, providing guaranteed cutting; the realization of design solutions; the optimization of cinematic and dynamic parameters of automatic thread cutting mechanism.
