Patent attributes
A jaw (39) for crimping a generally cylindrical compression sleeve (34) in a compression coupling is disclosed in, which at least two support members (39, 41) are adapted to support at least two arcuately shaped dies (24) for movement toward and away from each other for compressing the compression sleeve (34) about an inner concentric pipe or tube (36) to an inner arcuate die surface corresponding in shape and dimension to a predetermined outer surface portion of the compression sleeve so as to engage and compress the compression sleeve when positioned thereabout and moved toward each other. The dies (24) each have at least one crimping roller (30) rotatably mounted adjacent the die surface. The crimping roller (30) is adapted to form a crimp on the compression sleeve and the inner member to form a mechanical attachment therebetween. Various combinations of die/roller arrangements are disclosed to encircle and compress a sleeve/pipe combination to form a compression coupling.
