Abstract

A plain stepped splice lay-out scheme is presented that can be used for splicing strips to one another that comprise longitudinally arranged cords. The strips can take the form of a conveyor belt, transmission belt, timing belt, elevator belt, a rubber track or a reinforcing strip. The splice is optimised for uniform bending stiffness and maximum strength retention. The cross section of the strip and the splice are substantially equal: there is no increase in thickness or width at the splice. The splice lay-out is characterised by the fact that the abutments (130)—those positions where cord ends (111, 121) meet—are positioned sufficiently far away from one another and by preference as far away from one another as possible. Preferred embodiments in terms of length common between cords of the different strips and local strength are given.
