Abstract
A device for decollating stacks of flat objects includes a stack magazine. The base of the stack magazine supports the stack and includes revolving rollers that form a continuously moving series of rollers, pass underneath the stack magazine, and roll along the lowest object of the stack. A conveyor system is arranged underneath the upper run of the series of rollers and extends at an angle to the series of rollers. The lowest object that is removed from the stack by one passing roller is deposited on the conveyor system. A suction device moves or suction devices move between the rollers in the cycle in which the rollers pass underneath the magazine. The suction device or devices pulls or pull down one lateral edge of the lowest object between two rollers. The leading roller still supports the stack via the object and the trailing roller passes between the object and the object situated above so as to cause a secure separation of the lowest object from the stack. In order to transfer the decollated objects from the first conveyor to the transfer conveyor such that their lateral edges extend parallel to the transport direction, the transferring conveyor system includes conveyor elements that move in parallel and are driven at different speeds.
