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: A plurality of I-beam segments is aligned end-to-end in a longitudinal series. An elongated flexible sheet is carried on each side of the aligned I-beam webs. A flexible lap plate interconnects juxtaposed pairs of I-beam webs and maintains the elongated sheets in a slidable relationship, such that the flexible sheets can move with respect to the webs when the track section flexes laterally.

Abstract: A conveyor belt cleaning device provides a belt scraper blade and a roller juxtaposed to the blade on its downstream side, relative to the direction of conveyor belt travel. Frictional contact between the moving conveyor belt and roller drives the roller. The scraper blade scrapes stringy materials from the belt and the roller pinches trailing stringy materials between the belt and the roller, pulling such materials from the blade.

Abstract: A press frame has a floored portion that defines a pressing area and a floorless portion that defines a discharge area. The frame carries first and second squeezing elements that are moveable between the pressing area and discharge area. Only the first squeezing element is powered, and it can be driven selectively toward or away from the second squeezing element to press and discharge screenings. A linking device limits the maximum separation of the first and second squeezing elements so that the first element pulls the second, together with processed screenings, to the discharge area in a discharge cycle. An interposer limits the minimum separation of the first and second squeezing elements so that the powered element pushes the nonpowered element back to the pressing area after the discharge cycle.
