A spacing drum comprising: a segment receiving drum section capable of receiving a predetermined number of segments per revolution of the drum from a procession of segments approaching the segment receiving drum section at a segment-feed spacing and a segment-feed speed; a segment releasing drum section capable of releasing the predetermined number of segments at a segment-release spacing and a segment-release speed; and a radial profile flight comprising a continuous arc segment extending across at least portions of the segment receiving drum section and the segment releasing drum section. Associated methods are also provided, including method of changing pitch along a spacing drum progressively with a radial profile flight.

A system for part transfer and transport, the system including: a first conveyor system for transporting a plurality of trays containing a two-dimensional grid of parts; a second conveyor system for transporting the parts to a predetermined destination in a linear arrangement; and a selection apparatus for transferring a linear array of parts selected from the grid of the first conveyor system to the linear arrangement of the second conveyor system, the selection apparatus comprising: a pick and place apparatus which may be cam driven for moving the parts; and a feed screw defining a plurality of singulated part spaces separated by a part pitch along the second conveyor to facilitate insertion of the linear array of parts into the linear arrangement.

A screw conveyor based fabric dyeing machine including a machine body inside which a screw conveyor including a conveying screw and a fabric support board is arranged and generally parallel to an extension direction of the machine body. Fabric moves through a dyeing tube arranged with the machine body to fall down onto the screw conveyor so that the fabric can be conveyed by the screw conveyor forward through the machine body to reach a guide roller and a nozzle to complete a cycle of circulation for subsequently re-entering the dyeing tube to be dyed therein. As such, water consumption can be reduced and dyeing performance is enhanced, achieving energy saving and carbon reduction, reducing contamination to the surroundings, and realizing green economy.

A conveyor belt (36) is arranged in at least one spiral conveyor unit (32) or (34) is arranged in tiers forming at ascending spiral stack (38) and/or a descending spiral stack (40). A ceiling or top sheet (58) is positioned over the spiral stack. A circulation fan (60, 62) draws spent thermal processing medium laterally from the tiers of the spiral stack, up the exterior of the stack and across the top of the stack above the ceiling or top sheet and through a heat exchanger (64) located above the ceiling. The treated thermal processing medium is then routed across the remainder of the diameter of the spiral stack and then down the side of the spiral stack diametrically opposite to the circulating fan thereby to enter the spiral stack in a lateral direction diametrically toward the circulating fan. At least one opening (70, 100, 200) is formed in the ceiling between the heat exchanger and the diametrically distal end of the spiral stack from the circulating fan thereby to provide an alternative flow path for a portion of the thermal processing medium to enter the spiral stack from above, thereby resulting in more uniform treatment of the work product being carried by the conveyor of the spiral stack.

A conveying apparatus suitable for sturdy articles, in particular flattened plastic bottles or the like, in a recycling plant, has an upwardly moving continuous conveyor that includes a horizontal conveyor and a vertical conveyor connected to the horizontal conveyor, both conveyors having a tubular housing in which a respective conveying screw is rotatably mounted. The inner wall of the tubular housing of the vertical conveyor and the associated conveying screw have a vertical driver bar disposed therebetween, projecting radially inward from the tubular housing and spaced from the conveying screw by a distance (a). The driver bar has cutting teeth on its longitudinal edge located at least facing the conveying screw. Preferably, the driver bar is fastened in an interchangeable manner on the vertical tubular housing and has cutting teeth on both longitudinal edges.
