ABSTRACT:
A flexible hinge-pin for coupling two complementary rows of fastening staples on the opposite ends of closed-loop conveyor belt or the like comprises a flexible central core such as a steel cable. The core is surrounded successively by an intermediate plastic sheath and a tubular outer jacket formed by twisting one or a number of strands of wire, either in the same direction of twist as the core or in the opposite direction. The intermediate sheath can be of plastic material filled with grease which is capable of flowing under the action of the relative movements of the hinge-pin components at the time of flexural deformation of the pin in order to ensure that a fraction of the grease spreads over the surface of the pin.
