Zusammenfassung:	An overlap seal for joining together two edges of reinforced thermoplastic material. A plurality of strands or bands of hot melt adhesive are applied adjacent the edge of the one sheet of thermoplastic reinforced material and the edge of another sheet is positioned above the first sheet. The sheets are brought together and pressure is applied so that the heat contained in the hot melt adhesive causes a fusion of the two edges of thermoplastic to create a high strength bond. Some of the bands of thermoplastic material flow together to form a wide band with narrower bands on each side to provide an overlapped seal having increased strength.
