Abstract

A chain link (10) of a curved conveyor chain has been proposed, which has a carrying device (12) for transport material. A head part (24) disposed under the carrying device (12) has a lateral bore (40) for a pin (48) of a first adjacent chain link (10). The head part (24) is adjoined by a fork-shaped section (26) with two legs (44), which encompass the head part (24) of a second adjacent chain link (10). The legs (44) and contain lateral bores (46). A pin (48) is also provided, which is contained in the lateral bores (46) of the legs (44) and in the head part (24) of the second adjacent chain link (10). Projections (52) protrude from the legs (44) and are designed to be guided in a guide profile and driven by means of a driving wheel. The object of the invention is to produce a chain link (10), which permits a favorable introduction of force. To this end, the protrusions (52) are disposed between the lateral bores (46) of the legs (44) and the at least one lateral bore (40) of the head part (24), viewed in the transport direction (33).
