In conventional conveyor chains of the bottle conveyor type, in which the chain links (2) are made of sheet metal, the hinge joint between the links comprise a transverse pin (16) mounted through two outer hinge parts (10) constituted by rolled up plate strips (8) projecting from one link, and a broad middle hinge part (6) made as a rolled up strip (4) projecting from the other link. The hinge pin (16) is narrower than the middle hinge part (6), whereby the links are mutually transversely pivotal, for horizontal curve driving of the chain. According to the invention, for increasing the pivotability without weakening the chain the front side of the middle hinge part (6) is maintained at full width, but its rear side is made with considerably reduced width. |
