Abstract: Endless Forms Feed Tractor Belt and Method of Making A forms feed tractor belt includes drive members molded around a thin, flexible band at longitudinal intervals. To make the belt, slots are first punched at longitudinal intervals in at least one side of the flexible band. Drive members are then molded around the band at the slots except for at least one drive memberless interval at each end of the band. The ends of the band are overlapped so that the slots of the drive memberless intervals coincide. Final drive members are then molded around the slots of each pair of coincided drive memberless intervals to complete the endless tractor belt.
