Abstract

A melter for heating and melting particulate hot melt adhesive into liquefied form is disclosed. The melter includes a heated receiver having an interior with an inlet and an outlet configured to receive particulate hot melt adhesive. A flexible hopper holds a supply of particulate hot melt adhesive, and a particulate hot melt adhesive feed allows particulate hot melt adhesive to be directed from the flexible hopper to the inlet of the heated receiver. Flexible bag system capable of dispensing granular hot melt adhesive. The flexible bag system includes a hinge device that contacts the flexible bag body and manipulates the flexible bag body to maintain flowability of the particulate hot melt adhesive from the outlet.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application No. 62 / 115,964, filed February 13, 2015, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention generally relates to hot melt adhesive systems. Background technique [0004] Hot melt adhesive systems have many applications in manufacturing and packaging. For example, thermoplastic hot melt adhesives are used in carton sealing, housing sealing, tray forming, pallet stabilization, nonwoven applications including diaper production, and many others. Hot melt adhesives often come in the form of solid or semisolid pellets or granules. These hot melt adhesive particles are melted into liquid form by a melter, and the liquid hot melt adhesive is finally applied to objects such as workpieces, substrates or products by means of a dispensing device suitable for the application. [0005] Unmelted hot melt adh...
