Abstract

Bonding of the ends of a flat drive belt material to a polyamide drive belt, which have complementary configuration in the plane of the belt and contact surfaces perpendicular to this plane, involves (a) applying a resorcinol or cresol soln. or HCOOH or mixt. of these to the contact surfaces, (b) contacting the ends, (c) fixing the ends with a clamp and pressing perpendicular to the longitudinal axis of the belt, and (d) placing the fixed ends with clamp in a hot press and bonding the contact areas for 5-20 min. at ca. 100 deg.C and 0.5-3 bar. USE/ADVANTAGE - The diffusion process avoids the drawbacks of melt bonding and uses a polyamide materials resistant to temps. up to 150 deg.C which have high tensile strength, robustness and flexibility. Faulty bonds due to incorrect overlaps are rare and the bonds can be made by unskilled workers. The bond has excellent alternating bending strength up to 150 deg.C with a forced operating life of 140 h., cf. 100 h. for a similar bond produced with an angled or stepped configuration and 140 h. at max. 60 deg.C for a welded zig-zag bond in a thermoplastic resin drive belt.
