A drawing is given of a device used in winding filaments on a specified pitch around a drum of any diameter. The simple digital controller was developed to synchronize the filament feed device (moving parallel to the drum's axis) with the rotation of the drum. The drive for the filament feed screw utilizes a digital stepping motor that requires 200 steps for one complete revolution. Thus, for a screw pitch of 0.2 inches, the pulse resolution is 0.001 inch along the drum's axis for each step of the motor. A digital encoder of 128 pulses per revolution was attached to the axis of the drum, and the encoder output was routed through a quadrature decoder which supplies a pulse and direction output. The pulses are routed through a counter/rate-multiplier circuit that has digital thumbwheel switches to select an output of from 1 to 127 pulses for each rotation of the drum. These pulses are then fed to the stepping motor drive translator, resulting in from 1 to 127 thousandths of an inch advance of the filament lead screw for each rotation of the drum. The thumbwheel switches are in octal code, although decimal switches and binary coded decimal rate multipliers could be used. The modules listed on the drawings are manufactured by Digital Equipment Corporation.
