Abstract
The joining device is constituted by U-shaped staples fixed to the ends of the conveyor belt. The staples (1) comprise in their concave part a ring (3) of a wear resisting material the wear being due to the friction, and which has also good slipping properties. A tightness stripe (8) links the rings (3) and therefore the staples (1). The tightness stripe (8) comprises blades (9) which form a double tightness barrier in the gaps which are present between the front part (14) of the conveyor belt (13) and the front convex part of the opposed staple. The staples (1) are connected by means of a linking and hinging rod (15) threaded across the rings (3) of the successive staples (1) belonging alternately to one and to the other staple row. When mounted the rings (3) are in abutment against the front part (14) of the conveyor (13).
Claims29
A joining device for conveyor belt comprising two rows of generally U-shaped staples adapted to be fixed on the edge of each end of a conveyor belt (13) by means of pointed head nails (6), a convex part of the U-shaped staples (1) projecting beyond the edges forming each end of the conveyor belt, a concave part for the U-shaped staples (1) forming a succession of eyelets bounded by the said concave part of the staples and by the edge of the end of the conveyor belt to which the staples are adapted to be fixed, the staples of a first row of the two rows being placed between the staples of the second row of the two rows, in such a way that the eyelets of the staples of each of the two rows are in alignment in the transversal direction of the belt, a metallic rod (15) which forms a linking and hinging axis being threaded across these aligned eyelets, wherein a ring (3) is fixed to the concave part of each one of the U-shaped staples, the metallic rod (15) being threaded across each said ring of successive rings belonging alternately to the first row and to the second row of said two rows of staples (1).
