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.
A splice connecting a first strip to a second strip, both strips comprising a number ‘M’ of parallel cords in a strip matrix, where, in a splice arrangement, each cord end of said first strip abuts to a cord end of said second strip at an abutment, and wherein at least one group of ‘N’ contiguous cords is present with ‘N’ being equal to or larger than 12, wherein the distance taken along the splice between the first and last abutment of said at least one group is ‘Lgroup’ and said abutments within said group are regularly spaced apart over said length ‘Lgroup’ by a number of intervals, said interval being the smallest longitudinal distance between any pair of abutments within said group, wherein
