Abstract

An apparatus for continuously forming thermoplastic adhesive cartridges. A
molten thermoplastic adhesive supply provides a supply of molten adhesive to a pump (12) downstream from the molten thermoplastic adhesive supply. The pump (12) then provides a molten thermoplastic adhesive melt stream which passes through a screen filter (20) downstream from the pump (12) to prevent the discharge of impurities in the molten thermoplastic adhesive melt stream from the pump (12). A temperature-controlled conduit downstream from the pump (12) then lowers the temperature of the molten plastic melt stream to closely above its softening point. A continuous molder (14) located downstream from the melt pump (12) receives the molten plastic melt stream from the melt pump (12) to form the thermoplastic adhesive cartridge continuously.
