ABSTRACT:
A machine for applying adhesive wax is provided with a pan for receiving the wax and a pair of rollers defining a bite therebetween through which sheet material may be passed. A lower one of the rollers passes through the adhesive both and transfers adhesive to the back of the sheet material. A heating element, connected to a thermostat, maintains the adhesive bath at a desired temperature. A motor, provided for rotating the rollers is interconnected with the heating elements such that actuation of the motor is inhibited absent actuation of the heating element. Additionally, a thermostatic switch may be interposed in the adhesive bath to prevent actuation of the motor unless the bath has reached a predetermined temperature.
