Abstract: 688,543. Feeding sheets. BACKHOUSE, H. T. Dec. 14, 1950 [Dec. 14, 1949], No. 32142/49. Class 100(i) In sheet-feeding apparatus in which a succession of partly overlapped sheets are fed as a stream over a layboard to a position where each sheet is brought to rest and registered, and registration of each underlying sheet is effected while the overlying sheet is being removed, the tendency of each underlying sheet to follow the overlying sheet during the removal of the latter is overcome by the provision of presser means which press on the sheets immediately behind the usual front lays or stops on the layboard. As shown, the front lays 30, provided with scraper edges 31, have been moved to project above the layboard 1 to register the lower sheet 34, and the upper sheet 35 is being removed. Air blasts, from nozzles 33 in a cross tube 32, are turned on to cause the sheet 35 to sag, which helps the lower sheet to break away therefrom for interception by the stops. In a modification, combined front lays and scrapers, as described in Specification 657,618, co-operate with presser means comprising star-wheels freely rotatable on studs carried in slotted arms secured to a shaft which is oscillated by cam means. When the front lays are raised to hold the upper sheet off the layboard, the star-wheels are lowered to apply pressure to the upper sheet just behind the lays. Specification 427,041, also is referred to.
