Abstract: A servo control system for adjusting adhesive film thickness on a glue machine glue roll, wherein the glue machine includes a glue roll, a metering roll, and a glue gap defined between the glue roll and the metering roll. The system includes a servo motor for driving a glue gap adjusting mechanical linkage, a position encoder integrated into the servo motor, and a servo position controller coupled to the position encoder.

Abstract: A servo control system for adjusting adhesive film thickness on a glue machine glue roll includes a servo motor for driving a glue gap adjusting mechanical linkage, a position encoder integrated into the servo motor, and a servo position controller coupled to the position encoder. In addition, an operator control interface coupled to the servo position controller directs the operation of the servo motor. The operator control interface includes a processor and a memory storing instructions for execution by the processor. The instructions are responsive to position encoder feedback for turning the servo motor to achieve a desired glue gap size, for example, in accordance with a selected velocity profile for the servo motor. The velocity profile typically specifies servo motor velocity between a start position (e.g., a current glue gap size) and an end position (e.g. the desired glue gap size). The control system may determine the desired glue gap size as a function of a glue machine line speed.
