Abstract
PURPOSE: To enable the use of a compact suction pump, by selectively operating passage open/close means depending on the size of the sheet to open or close air passages which connect a negative pressure unit to some of numerous suction holes provided in a drum for sucking the sheet.
CONSTITUTION: When the sheet of large size (B4) is wound around the surface of the drum 2, a cover 25 provided inside the drum is located in a position A and a negative pressure generator 23 containing a fan and a motor is driven. When the drum 2 is rotated and the sheet S is sent out in the direction of an arrow in the figure, the front end of the sheet is sucked on a row of suction holes A. After that, the sheet S is sucked on groups of suction holes B1, B2..., B12, C, D, E in that order according as the drum 2 is rotated. When a sheet of small size (A4) is wound, the cover 25 is displaced by 1/2P through a control means and a projection 25A and some of the suction holes 21 are shut off depending on the size of the sheet.
