<p>APPARATUS FOR MELTING AND DISPENSING THERMOPLASTIC MATERIAL An apparatus for melting and dispensing thermoplastic material comprising a hopper, a grid melter, a reservoir and a pump. At least a portion of the hopper is enclosed within a shroud so as to define an air flow chamber around the lower end of the hopper. Air is forced through this chamber when the apparatus is in use so as to cool the hopper and prevent molten material from backing up into the hopper.</p> |
