Abstract
A dripless, easily cleaned glue applicator for a machine for making two-piece paper cups comprises an outer body member in which there is a cavity that opens to a slot in a flat bottom surface of the member. The slot has a shape and size conforming to an area of glue to be applied. An inner member in the body member forces the longitudinally central portion of a resilient foam pad to bulge down through the slot and clamps the pad to the outer body member. The inner member also provides a glue chamber that is communicated with a pressurized source of glue and from which numerous bores, spaced along the length of the inner member, open downwardly to the pad. A top plate on the outer body member closes its cavity, holds the inner member in clamping relation to the outer body member, and provides for mounting the applicator.
