ABSTRACT:
Thin malleable metal foil is packaged in tape rolls or single sheets and is used to repair worn metal parts, such as rotatable shafts, surfaces subject to wear from lateral motion, and rusted or corroded sheet metal. The tape may also be used as a strapping tape to hold broken machinery parts together until a replacement part is obtained. The tape is designed to be temporary in nature, thus to serve as a means for effecting an emergency repair until a more permanent solution can be obtained. The tape may be selectively tapered along its width when it is used to repair a worn portion of a rotatable shaft, since the tapering will permit the tape to conform to a concavely-shaped worn surface in an even manner. To facilitate the degree of tapering, the tape surface may be provided with angulated scribe lines so as to permit a user to cut the desired taper depending upon the concaveness of the worn surface to be repaired. The tape may be perforated to facilitate lubricant retention and cooling; for even further lubrication, the tape may be impregnated with graphite or some similar lubricant. Additional features of the tape may include a gradual thickening of the tape along its longitudinal length so as to provide a stronger and more wear-resistant surface on that portion of the tape which will perform a direct load-bearing function. Additionally, the material from which the tape is made may be gradually increased in hardness along its longitudinal length so as to perform the same function. Also, the tape may be made of fine woven wires, for greater tensile strength and flexibility.
