Abstract: A conveying arrangement is provided for a transport member for conveying product. The transport member traverses on rollers inside a conveying arrangement which includes a plurality of tunnel shaped guide channel segments connectable together via end flanges. A continuous opening is provided on the underside of each channel segment in a conveying direction to accommodate a device attached to the transport member to take over conveying of the product. Guide rail elements inside the channel segments support run surface elements which present a rolling surface for the transport member. At least one run surface element has an excess length, relative to the length of the guide channel segment. An adapter element including a transition piece is positioned at least in a region of a separating plane between adjacent flanges to present a planar transition for the rolling surface of the at least one run surface element.

Abstract: Resilient clamps assemble modular sections of a serpentine conveyor belt at peripheral positions of mated interface walls and retain the walls in sealing, face-to-face contact while the belt moves through a laterally bending pathway. The clamps provide opposed latchkeys that register into boltways or recesses in the mated walls to lock the modular sections into fixed positions with respect to one another.

Abstract: The rotary disc conveyor system is formed of a series of units or pans linked together to form a continuous conveyor run. Each of the pans preferably includes a pair of rotary discs thereon, with all of the discs of the system rotating simultaneously and unidirectionally to convey material along the conveyor run. Each disc includes a series of generally radially disposed vanes thereon, to assist in sweeping the material along the conveyor. Guides may be installed along either side of the system, between each disc, to facilitate material flow and restrict return flow. Mechanical, hydraulic, or electrical power may be used to provide rotation of the discs. The rotary disc conveyor is particularly well suited for use in longwall coal mining for removing loose coal from the mining head and conveying it along the face of the wall to another transport system for removal from the mine.
