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