A device to apply a trim to textile surfaces is provided that can cut, fold, and adhere end pieces of the trim. The device includes a material holder assembly configured to hold and dispense a roll of trim material and a roll of adhesive material; a control and heating assembly including control inputs, status indicators, control electronics, a heating element and a heating chamber configured to receive the trim material and the adhesive material from the material holder assembly; and a cutting and forming compartment including drive rollers, a cutting device, a folding mechanism configured to fold cut ends of the trim material and the adhesive material, and pressing mechanisms to press the folded cut ends of the trim and adhesive material so that the folded ends are adhered to the remainder of respective trim material lengths.

A multi-phasic polymer blend for energy activated edge banding adhesion to a substrate is described. While the blend may be used for adhering edge banding to straight substrates, the blend is preferred for adhering edge banding to contoured substrates. The outer, hard, structural layer of the edge banding is formed from a polypropylene component. The polypropylene component at least includes polypropylene and an optional energy adsorber. The inner adhesion layer of the edge banding is formed from a multi-phasic polymer blend that bonds the outer layer of the edge banding to the substrate. The multi-phasic polymer blend at least includes a polyamide component, a polyolefin component, and a modified polypropylene component. Both the outer and inner layers forming the edge banding may be tinted to conform or contrast with the color of the finished substrate.
