ABSTRACT:
A machine for splicing or joining the ends of two precured rubber tread strips each having a pattern of ribs and grooves in one surface thereof. The machine includes first and second tread-clamping assemblies each of which grips the opposite surfaces of one of the tread strips between two elements and further includes power means for moving one of the assemblies toward the other in order to tightly abut the ends of the tread strips while heat is applied to effect vulcanization of a bonding material which previously has been inserted between the ends.
