ABSTRACT:
Apparatus for melting and dispensing solid thermoplastic material directly from a drum. The apparatus includes a base plate, a platen assembly mounted above the base plate, and fluid motors for effecting vertical movement of the platen assembly relative to the base plate. The platen assembly includes a follower, a heating platen located beneath the follower, and a pump for pumping molten thermoplastic material from the underside of the follower as the platen assembly is lowered into a drum supported atop the base plate. A drum hold-down mechanism is mounted on the top side of the base plate and is engageable with a drum supported upon the base plate so as to prevent the drum from lifting up off of the base plate as the platen assembly is lifted out of the drum. The hold-down mechanism includes a pair of hold-down plates spring biased into engagement with opposite sides of the drum, which hold-down plates have tapered leading edges engageable with the drum as the drum is inserted between the mounting plates so as to guide the drum between the plates and cam the plates apart against the spring bias.
