ABSTRACT:
A pintlepin is disclosed, for use to connect together adjacent ends of segments of an endless belt. The pintlepin has a pintle consisting of at least one filament having an outer diameter substantially identical to the diameter of the tubular opening formed by the intermeshed loops used as a seam at the adjacent ends of the segments to be connected. It also has a leader made of a rigid or semi-rigid material. This leader has an outer diameter smaller than the outer diameter of the tubular opening. It acts as a guide to facilitate insertion for the pintle through the tubular opening formed by the loops. A swager connects together the pintle and the leader. This swager consists of a tubing having a front portion and a rear portion in which the rear end of the lader and the front end of the pintle are respectively swaged. The front end of the pintle has a peripheral recess sized and shaped to receive the rear portion of the swager and thus prevent this swager from having an outer diameter exceeding the outer diameter of the pintle. This feature renders the insertion of the pintlepin much easier to carry out, The front portion of the swager also has a front edge which is forwardly downwardly bevelled. This feature reduces the risk of damaging the loops.
