Edge banding machine is used to cover the exposed sides of materials such as plywood, particle board or MDF, giving the appearance of a solid (or more valuable) material. can also be used instead of features such as face frames or molding. Thicker edgebanding requires a slight concavity to provide a tight glue line. The thickness can vary from .018" to 5mm or even more. Edgebanding can be applied to the substrate by using hot melt adhesives. Hot melt adhesives can be water or solvent based and they can consists of different raw materials (EVA, PUR, PA, APOA, PO). The machine that applies the edgebanding is called edgebander. An edgebander bonds the edgebanding to the substrate, trims leading and trailing edge, trims top and bottom flush, scraps any surplus and buffs the edge.
