Abstract

This invention relates to an axial and radial transmission mechanism for loop looper of sewing machines, having a radial transmission mechanism and an axial transmission mechanism provided between a loop looper shaft driving the loop looper and a main shaft for supplying power of the sewing machine. The radial transmission mechanism is driven by the main shaft to drive a main drive for driving a radial member provided on the loop looper shaft through a link and through a transmission member pivoted to a pivot, so as to cause radial rotation of the loop looper shaft. The axial transmission mechanism is provided on the loop looper shaft with an axial member that directly extends to and is driven by the main shaft of the sewing machine so as to reduce relevant structure required fro driving the axial transmission mechanism along the axial direction, thereby simplifying the mechanism for driving the loop looper and to ensure proper transmission.
