PCT No. PCT/US95/14474 Sec. 371 Date May 8, 1996 Sec. 102(e) Date May 8, 1996 PCT Filed Nov. 7, 1995 PCT Pub. No. WO96/15057 PCT Pub. Date May 23, 1996This invention relates to a feed system for conveying loose pieces of a coarse particulate or pelletized hot melt material such as adhesives from a storage container to a melt tank. The system includes a transition hopper having insulation between the hopper and the melt tank to prevent premature melting of the loose adhesive pellets or pieces before they pass into a melt tank. An air supply for providing air pressure to the interior of the hopper can be attached to the hopper to prevent vapors from rising from the hot melt tank into the transition hopper and a vent opening for exhausting vapors from the hot melt tank can be located in the top of the melt tank.
