Abstract: A power supply includes a battery source supplying power and a voltage converter circuit. The voltage converter circuit converts the power to the input voltage supplied to other circuitry. The voltage converter circuit varies the input voltage in response to a load current drawn by the other circuitry from the power supply.

Abstract: A collecting device for forming a printed product includes a conveyor and a plurality of printed material delivery devices, the plurality of printed material delivery devices including a first delivery device for first printed materials and a second delivery device for second printed materials. A first transfer device is assigned to the first delivery device and delivering the first printed materials to the conveyor and a second transfer device assigned to the second delivery device and delivering the second printed materials to be collected with the first printed materials on the conveyor. Each of the first and second transfer devices have printed material buffer positions between the respective first and second delivery devices and the conveyor, which permit advantageous reduction in the amount of waste.

Abstract: A gathering device for forming a plurality of printed products includes a transfer device having a plurality of grippers. A first sheet material feeder delivers first sheet material to the plurality of grippers and a second sheet material feeder delivers second sheet material to the plurality of grippers, the second sheet material feeder being downstream of the first sheet material feeder. A conveyor receives the first or second sheet material from the grippers. A method is also provided.

Abstract: A folder for processing a stream of printed signatures from a printing press and related method. The signatures have a desired path with a path edge and each signature has a lead and trail edge. The folder comprises a plurality of sensor sets, each sensor set for determining if the lead and/or trail edge of the signature deviates from the path edge by more than a certain tolerance.

Abstract: A mailroom conveyor system for transporting and handling a stream of printed and folded signatures supplied by high speed tapes of a folding apparatus of a printing press. The system includes a plurality of grippers, a rail system for guiding the grippers, an electric linear drive system for individually driving the grippers in the rail system, and a control system coupled to the electric linear drive system for individually controlling the movement of the grippers in the rail system.

Abstract: The present invention is related to an apparatus for delivering flat products, such as signatures, in a folding apparatus of a rotary printing press. At least one fan wheel assembly has a plurality of fan blades separated from each other by fan wheel pockets. The fan wheel pockets are defined by surfaces of the fan blades. A first surface of each fan wheel pocket is configured to cause the signature to take on an energy dissipating state.

Abstract: A diverter mechanism for signatures in a folding apparatus is provided including a set of high-speed tapes (3) for conveying signatures in a conveying plane (1) toward delivery stations (12, 13). Rotating diverting elements (7.1, 7.2) are integrated into the path of the high speed tapes (3). Each of the diverting elements (7.1, 7.2) has at least two rotatably mounted guiding surfaces (10) that alter the diverting direction of signatures upon rotation of the diverting elements (7.1, 7.2).
