Abstract
The present invention generally relates to a hot molten adhesive application machine. More specifically the present invention discloses a unique hot melt adhesive application machine having a novel construction whereby the reservoir of molten adhesive material is heated from within the molten adhesive. The adhesive pump, discharge hoses, and discharge applicators are heated by electrical resistance heating elements that may operate on 120 or 240 volt current. Further, a novel axial pump piston is disclosed whereby the pump cylinder bore may be machined to a lessor tolerance standard than previous pumps of this type.
