ABSTRACT:
The invention relates to a conveyor chain for machines for tensioning lengths of material, with pairs of outer fishplates and pairs of inner fishplates flexibly connected by chain joint bolts and with support members for grippers or needle plates. The pairs of inner fishplates are supported by means of joint sleeves on the chain joint bolts, needle bearings are arranged between the joint sleeves and the chain joint bolts and ball bearings are provided on the outer peripheral surfaces of these chain joint bolts. These ball bearings are constructed like roller bearings with particularly thick outer races, and the outermost outer fishplates rest with a bore clearance on the chain joint bolts. This conveyor chain is distinguished by a simple and stable construction which requires little maintenance.
