ABSTRACT:
For liquefying hot melt adhesive, a hopper is provided at its lower region with one or more discrete upwards projections (for example a single, fluted cone), with means for heating the projection(s). In use, a unitary mass of hot melt adhesive is lowered into the hopper to become supported on the projection(s), as a result of which the unitary mass is progressively melted and the melted adhesive flows from the bottom of the hopper.
