Device for feeding of sheets to sheet processing machine has cylinder bore formed in second piston which in second cylinder bore formed in housing can move up and down between upper normal position and lower separating position

摘要

The device for the feeding of sheets to a sheet processing machine has a separating sucker for gripping and lifting the uppermost sheet in a stack and with a reciprocating piston (12) dividing a cylinder bore into a cylinder chamber and annular chamber. The cylinder bore is formed in a second piston (3) which in a second cylinder bore formed in a housing (1) can move up and down between an upper normal position and a lower separating position. The second cylinder bore is divided by a second piston into a second cylinder chamber and a second annular chamber (9) connected to a vacuum source.
