Abstract
A hot melt dispensing apparatus for converting solid thermoplastic material to molten thermoplastic material and for dispensing the molten thermoplastic material comprises a solid thermoplastic material receiving hopper, a vibrated feed chute mounted beneath a bottom opening in said hopper, which vibrated feed chute has a discharge opening laterally offset from the vertical plane of the hopper, and a heated reservoir mounted beneath the discharge end of the feed chute. The reservoir is laterally offset from the hopper so that heat rising from the reservoir does not melt solid thermoplastic material contained within the hopper or within the feed chute. The hopper is rectangular in configuration and comprises three vertical walls and one sloping wall angled relative to a bottom discharge opening of the hopper.
