Abstract

1398061 Feeding sheets HEIDELBERGER DRUCKMASCHINEN AG 5 April 1973 [26 April 1972] 16356/73 Heading B8R Sheets are separated from the top of a pile 16 by suckers 16 and during each feed cycle a rotating crank pin 7 withdraws a piston 5 in a cylinder 9 to produce vacuum which is communicated to the suckers through hoses 11, 13. On the return stroke of the pin 7, a rod 35 on the cylinder 9 acts on a lever 31 to open an outlet of a valve 21 to admit air to the hose 13 and release the vacuum. If a double or slanting feed is detected, an electromagnet 27 opens another outlet of the valve to release the suction and drop the sheet or sheets back on the pile, the sheet-handling machine such as a printing- machine also being stopped. When the machine is re-started by an operating lever, the magnet closes the outlet to resume the feed.
