Patent attributes
A chain cover includes side covers each formed with a shaft hole for receiving a coupling pin of a roller chain, two top covers each having a length substantially equal to a chain pitch of the roller chain, and a coupling plate coupling the top covers adjacent to each other. The side cover at each end of the chain cover has a convexly arcuate front edge concentric with the shaft hole and a concavely arcuate rear edge similar to the front edge, and the coupling plate and two top covers cooperate to form a slat. A plurality of these chain covers can be mounted on a plurality of parallel roller chains to cover the top and sides of each roller chain and form a flat goods conveying surface between the roller chains, thereby forming a slat conveyor which is less expensive than a roller conveyor and provides excellent conveying stability.
