An improved method of splicing multi-ply belting material to form an endless belt. The upstream portion of the splice on each side of the belt has at least two plies of the material which have not been split, while each side of the belt on the downstream portion of the splice presents an overlying flap to a roller.

A method of splicing the ends of three-ply belting material to form an endless belt, comprising the steps of: (a) forming a tongue at the upstream end of the belting material by removing a first predetermined length of the outer ply on the first side of the material and a second predetermined length

A method of splicing the ends of three-ply belting material to form an endless belt, comprising the steps of: (a) forming a tongue at the upstream end of the belting material by removing a first predetermined length of the outer ply on the first side of the material and a second predetermined length of the outer ply on the second side of the belting material, the second predetermined length being greater than the first predetermined length; (b) forming a groove in the downstream end of the belting material by removing a portion of the center ply of the downstream end which is equal in length to the second predetermined length and by removing a portion of material, which is equal in length to the first predetermined length, from the outer ply of the downstream end which is to mate with the first side of the upstream end; (c) inserting the tongue at the upstream end of the belting material into the groove in the downstream end of the material to mate said upstream and downstream ends; and (d) forming a secured joint between the upstream and downstream ends of the belting material.
