ABSTRACT:
A continuous conveyor belt of the type useful for transporting materials such as paper products from one location to another, and including a polyamide core and elastomerized top and bottom surface coatings on the core, is formed into a continuous band by a process which involves the use of a hot melt foil sheet placed between the ends of the belt. The foil sheet includes a polymer material which softens under heat and pressure, and which solidifies when cooled to bond together the ends of the belt. Typically each end of the belt is feathered, and the ends are juxtaposed in an overlapping relationship with the foil sheet therebetween. Temperatures of 325.degree.-425.degree. F. (163.degree.-218.degree. C.) are typically used to soften the adhesive.
