In a device for rotating a stack of two-dimensional sheet-type or film-type products, or a stack thereof, at least two drive-roller pairs (11, 12; 13, 14) which are disposed beside one another so as to be spaced apart for conveying the products (1) are provided, the drive speed of said drive-roller pairs being modifiable in such a manner that the two roller pairs, oriented toward the same conveying direction, are operable at different speeds. |
