Abstract: Products which are somewhat self-supporting are carried in tandem on a first conveyor toward a second conveyor with an edge of the product transverse to the direction of travel. When each product reaches the point of transfer between conveyors, it is transferred downwardly on edge onto the second conveyor and the products are reverse-shingled in batches on edge in a partially upright fashion on the second conveyor. Each batch of products is then moved on the second conveyor on edge by a loader for insertion into a container or for transfer to another device for further processing or handling. When inserted into a container, a wall of the container is temporarily bowed inwardly to guide the products while they are being loaded into the container.

Abstract: A rotary transfer device includes a rotating transfer disc and a valve plate overlying and concentric with the disc. A series of fluid conduits extend radially inward from the disc perimeter, or from a face of a disc near the perimeter, and are open at their inward ends to the disc top surface beneath the valve plate. An arcuate vacuum groove, and a spaced apart air pressure groove, are formed in the bottom surface of the valve plate and open to a vacuum source and pressurized air source, respectively. Rotation of the disc brings the inner end of each conduit into intermittent fluid communication with the vacuum groove at an object acquiring position where the outer end of the conduit is near the feed station. Further rotation of the disc brings the inner conduit end into fluid communcation with the pressure groove, with the outer conduit end near an object discharge position.
