Hot Melt Gumming Machine is a type of industrial gluing or coating machine that applies hot melt adhesive (solid at room temperature, liquefied by heat) onto substrates such as paper, cardboard, films, label stock, tapes, or similar materials for bonding or lamination. ​ What it does Heats solid hot melt adhesive in a melting or premelter unit, then pumps it in liquid form to the coating or gumming head. ​ ​ Applies a controlled thin layer of adhesive (often 15–80 gsm range) to a moving web of material like paper, release liner, films, or fabric. ​ Often laminates the coated substrate with another substrate (e.g., siliconized paper + face paper for sticker labels) and rewinds it into rolls or sheets. ​ ​ Typical applications Self-adhesive label stock and sticker paper making (chromo paper + silicon release paper + PSA hot melt). ​ ​ Adhesive tapes: double‑side tape, foam tape, medical tapes, cloth tapes, aluminum foil tapes, craft paper tapes, and specialty technical tapes. ​ Specialty products: insect sticky rolls, yellow sticky cards, and other coated products that require precise hot melt layers.
