Abstract: A booklet of sheets folded to create a curved spine is fixedly held by clamping jaws adjacent to the spine and a forming roller is passed one or more times along the length of the protruding spine with sufficient pressure to produce a flattening of the curvature of the spine. The deformation of the spine of the booklet means that the sheets lie flat after the treatment. A retractable stop plate defines the amount by which the spine protrudes beyond the jaws.

Abstract: A conveyor system for transporting cigarettes between a making machine and a packing machine includes a mass flow conveyor (204) for transporting cigarettes directly and a reservoir system (212) in which successive batches of cigarettes comprising portions of the stream on an input conveyor (204) are diverted when required into compartmented containers (224). Transfer to the containers is made by way of a plunger (232) and shuttle (234) arrangement which allows the stream to move continuously during transfer of a batch. Unloading containers to reform a continuous stream may involve use of a similar plunger and shuttle arrangement so that the reformed stream can move continuously on an output conveyor (218). The input and output conveyors (204, 218) may be provided with retractable spaced partitions to bound the ends of batches of cigarettes transferred from or to the respective conveyor.
