Abstract:
1. Apparatus configured to vary an amount of a hot melt adhesive carried a peripheral surface of a rotating adhesive application wheel which is partially immersed in a reservoir of liquefied hot melt adhesive, said apparatus comprising a motor for rotating said wheel about an axis, and a computer control system for controlling the operation of said motor, wherein as said wheel rotates up out of said adhesive in said reservoir a layer of adhesive is formed on said peripheral surface of said wheel for application to an object, and a sensor for sensing the depth of said layer of adhesive on said peripheral surface of said wheel, said computer control system being responsive to said sensor for varying the speed of said motor so as to adjust the depth of said layer of adhesive, said apparatus further comprising a temperature sensor for monitoring the temperature of said adhesive in said reservoir, said computer control system being further responsive to the temperature of said adhesive in said reservoir so as to control the speed of said motor so as to vary the depth of said layer of adhesive on said wheel.
