  • Method of installing an insulating sleeve on a staple
    Patent number: 3940844
    Abstract: An insulated staple is formed by a U-shaped body member, and a piece of flexible, plastic tubing bent in a U-shaped configuration and installed on the body member. The plastic tubing is cut along a longitudinal wall portion to form a longitudinally extending opening at the central region of the tubing. The insulated staple is then assembled by inserting the opposed and parallel legs of the body member through the longitudinal opening and out through the axial ends of the tubing so that the body member is lined along its inner periphery between the end portions of the tubing mounted on the opposed and parallel legs. The method for making the insulated staple comprises cutting the longitudinal opening in the tube, bending the tube in a U-shaped configuration and inserting the legs of the body member through the axial ends of the tubing so that the pointed tips are exposed and the inner periphery of the staple is lined between the end portions of the tubing on the parallel legs.
