Abstract
An apparatus and method for applying glue is provided in which glue and water are selectively provided to a spray nozzle wherein the water supplied to the nozzle is used to remove any residual glue present after a gluing application. In one preferred embodiment, an outer conduit surrounds an inner conduit defining a first channel therebetween. The inner conduit supplies glue and the first channel supplies water. The outer conduit and the inner conduit are slidably engaged with each other. At least one spray nozzle is in communication with an outer conduit orifice. Slide conduit orifice valving provides selective communication of the outer conduit orifice with an inner conduit orifice and the first channel for selectively supplying glue, water, or neither to the spray nozzle.
