ABSTRACT:
An improved fluid-operated dispensing apparatus for use in receiving, processing, and applying rods of hot-melt adhesive. Important characteristics of the apparatus include an air-cooling means adapted to operate when the dispensing function is not being operated, and a means for gripping the adhesive rod to assure a uniform advance through the apparatus to the heating zone. Moreover, the use of a drive piston assembly, which is annular with respect to the rod being processed, enables the manufacture of an unusually compact tool.
