Operatively associated with each of the cutter tools are feed means for the infeed and removal of a flat structure.

Abstract: An apparatus for transferring successively arriving piece goods, especially printed products, from a first individual conveyor to a second individual conveyor, each of the individual conveyors being provided with tandemly arranged, controlled grippers each of which serve to grip one of the piece goods. Between both of the individual conveyors there is arranged a third revolving individual conveyor equipped with controlled entrainment members. Each of the entrainment members serving to seize or engage one of the piece goods. The conveying-active run of the third individual conveyor can be introduced at its end regions into the conveying paths of the first and second individual conveyors. A drive which is controlled by the first and/or the second individual conveyor is provided for the third individual conveyor.

Abstract: An apparatus for stacking printed products or the like continuously arriving from a conveyor and moving along a conveying path of travel, especially printed products arriving in an imbricated product formation, wherein there are provided a plurality of clamping elements elastically pre-biased towards one another. The clamping elements are displaceably guided through the operable zone of a driven spreader mechanism and due to the action thereof temporarily brought out of their mutual clamping position. The path of movement of the clamping elements at the region of the spreader mechanism penetrates or passes through the path of travel for the incoming or arriving printed products defined by the conveyor.

Abstract: An apparatus for folding printed products comprising a revolving cell wheel with compartments, each for receiving a printed product to be folded. Each compartment has a folding blade driven to be displaceable to-and-fro between a work stroke and a return stroke. The folding blade, prior to the start of its work stroke, moves past a stationarily arranged folding rail common to all compartments and during the course of its work stroke has its side which trails, as viewed in the revolving direction, move past a contact rail or contact roll arranged in each of the compartments. Infeed means serve to deliver a printed product to the leading side of the folding blade prior to the start of its work stroke in each compartment.

Abstract: A device for equalizing the spacing of printed products, such as newspapers, comprises a plurality of spacers movable in a path parallel to the path of the products. Each of the spacers receives the leading edge of a printed product and is driven thereby to a braking device that causes each spacer to abut the preceding spacer. The printed products are carried by a conveyer belt system and a sill raises their leading edges ready for reception by the spacers. After leaving the braking device, the products are deposited from the spacers which are then returned to a magazine to receive further products.
