Abstract
A succession of rectangular mats, consisting essentially of asbestos fibers or other filamentary material held together by a wet hydraulic binder such as cement, are conveyed by a series of trays through the gap between a pair of horizontal platens of a press. The upper platen carries a die for trimming the edges of a mat to be compacted, with the tray acting as an anvil. The trays are linked near their leading ends with two parallel, endless conveyor chains and have their trailing ends supported by rollers on rails which parallel the upper and lower runs of the chains and which form ramps for guiding these rollers onto the lower level downstream of the press and onto the upper level upstream of the press whereby each tray runs horizontally through the press between a loading and an unloading station.
