Mechanism of material movement and its description

the article provides the kinematics chart of mechanism of material movement of sewing machine and determination of law of lath motion at the different parameters of the system and its equalization. It also determins concrete values of linear speed of point Е of lever – laths at moving of material in sewing machines. A mechanism is worked out with the storage of energy as a conical spring, that operates at the horizontal moving of lath and a mechanism is executed as the reserved kinematics chain
