ABSTRACT:
Rivets to be used for securing end connectors to cord-reinforced conveyor belts and having a body with a head at one end and a bore at the other end, are disclosed. To facilitate driving such a rivet through the belt, a sharp-pointed elongated mandrel is loosely fitted at one end of the body thereof into the bore at the end of the rivet and is releasably secured to the rivet body by a strip of adhesive tape. The mandrel body is thinner than and at least as long as the body of the rivet and has a conically flaring portion adjacent the end connected to the rivet. When the rivet and mandrel combination is driven through the belt, the mandrel forms a pilot hole which facilitates subsequent entry and passage of the rivet, and the tape is automatically stripped off as the rivet/mandrel juncture reaches the belt body, so that the mandrel self-releases from the rivet as soon as the bored end of the latter has fully passed through the belt. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.
