Abstract
The device comprises a magazine for a stack of sheets, a sheet-extracting head which can be connected to a vacuum source and is rotatably mounted on a turntable which carries a number of columns, and means for counting the number of revolutions performed by the turntable. A first safety device indicates whether the sheet-extracting head has taken more than one sheet and a second safety device checks whether the extracting head has in fact taken at least one sheet. A circular sector of the first safety device is pivotally mounted on the extracting head. The radius of the sector is equal to the distance between its geometrical axis and the cylindrical surface of the next column increased by a value between the thickness of a single sheet to be counted and the sum of thicknesses of two sheets.
