Abstract: An automated applicator (120) for forming a welded identification sleeve (34) around an elongate object, such as a conductor (16), includes a base (124, 146, 148) defining a receiving surface (186) for receiving the conductor. A reversible line-feed printer (18) for feeding a weldable material strip (24) is positioned adjacent the receiving surface of the base. The printer is capable of selective operation in an advance mode to advance the leading end portion (22) of the material strip toward a first end of the base and transversely past the conductor, and a reverse mode in which the material strip is retracted away from the first end of the base. The applicator includes a guide member (151) mounted on the base and positionable adjacent the receiving surface for guiding the lead portion of the material strip, when advanced by the printer, around the elongate object. When so advanced, the leading end portion of the material strip overlaps the material strip in order to wrap the conductor.
