Abstract: An apparatus for installing insulation on a U-shaped metallic body member to form an insulated staple. The apparatus receives both the U-shaped body member and a section of tubing, and assembles the tubing on the body member so that the staple can be driven into a supporting object and attach a conduit captured by the staple to the object without having direct physical contact between the metallic body member and the conduit. The apparatus assembles insulating tubing on the U-shaped body member so that the portion of the member which receives the blows of a hammer during a stapling operation is openly exposed and the inner periphery of the U-shaped member adjacent the captured conduit is entirely covered by the walls of the tubing which provides the insulating characteristics. The apparatus is adapted to install a standard plastic tubing on a conventional staple body member and, thereby, produces inexpensive, insulated staples efficiently.
