CIRCUIT FOR CONTROLLING THE THREAD VELOCITY IN WINDING EQUIPMENT WITH A TRAVERSING MECHANISM

摘要

A circuit for controlling the thread velocity in universal winding machines having a traversing mechanism is disclosed. The circuit develops a correction factor, derived from the diameter of the winding on the spindle or the speed of the motor driving the spindle. This correction factor is then used as an input to the thread velocity control circuit to maintain a constant velocity for the thread being fed to a spindle.
