Abstract

1470994 Feeding sheets MARTIN SA 31 May 1974 [31 July 1973] 24249/74 Heading B8R Sheets 11 are separated from the bottom of a pile supported on a vacuum table by a reciprocating pusher device comprising claws 17 carried on a bar 4 movable beneath the surface of the table. The surface of the table comprises a series of parallel bars 9 between which the claws project to engage the rear edge of the lowermost sheet. A plate 18 is connected to the bar 4 to prevent leakage of vacuum through the rear portion of the table. The sheets are fed beneath stop 12 to rollers 15. To enable the supporting of different lengths of sheets the table may have a telescopic rear section, Fig. 5, which slides within the front section. In this case the bars forming the surface of the rear section comprise upper and lower members 30 and 28 respectively and which slide on upper and lower surfaces of the bars of the front section. The free ends of the bars are supported by brackets 29.
