Abstract
PURPOSE: To enable the use of a compact suction pump, by providing rows of suction holes in a drum, around which a sheet is wound, to separately suck the front and the rear ends of the sheet and setting different suction timings for the rows of suction holes.
CONSTITUTION: The drum 20 is rotated to a position A as a sheet involving pawl 23 is open. The sheet S is sent out by a pair of send-out rollers 69 synchronously with the rotation of the drum so that the front end Sa collides against the stoppers 25. After that, the pawl 23 passes under a squeeze roller 64 and is closed to pinch the front end of the sheet S. A solenoid valve not shown in the figure is opened synchronously with the pinching of the front end of the sheet to apply a suction force through a suction hose 54, suction pipes 39 and suction holes 36 to suck the sheet S and the involving pawl 23. When suction holes 52 are shut off by the front end of the sheet S, another solenoid valve is opened to apply a suction force through the suction hose 54, suction pipes 53 and the suction holes 52.
