- a sheet-fed press leads individual sheets through printing units, dryers, a cooling unit and other possible Processing units before the sheets are finally folded and / or stacked.
- the sheetfed press does not need a cutting machine in the same way as a web-fed rotary printing press that requires cutting the web for processing, however, both types of press signatures as a stream of Transport printed products during press operation.
- a stream of printed products can be gripped by a gripper conveyor, such as is generally known to the person skilled in the art. It is often desirable to include this product stream process, for example by dividing it into two or more separate streams or subjected to certain other processing such as conveying and stacking.
- the conventional method of dividing a product stream, in particular Print products is to seal the original product stream over a vacuum belt pull, which runs slower than the conveyor system, and any other (i.e. second) signature release from a gripper conveyor as soon as the signature in question releases the vacuum belt contacted.
- this often leads to a relative movement between the signatures, which are carried out on the vacuum belt and the signatures which are carried out by the Conveyor system remain in place. As a result, correct alignment and fixed Division (the distance between the same points of two consecutive signatures in a product stream) of the signatures supplied to the vacuum belt is not guaranteed become.
- each gripping device comprises a stationary one Jaw, a rotatable jaw and a plate-shaped stop.
- the rotatable jaw against the action of a closing spring by a Cam structure or similar device rotated.
- the products are initially accelerated and then pushed into the open gripper mouth until it hit the stop butt so that the printed products are aligned in the area of their leading edges become.
- the printed products remain on their trailing edges at least as long under the conveying action of the belt conveyor until the gripper units are closed.

- the grippers are able to close the signatures at one of their corners and behind grasp and can move into a position, with the signature on the grasped Corner is guided so that a product stream in a configuration of the leading corners or the "A-shaped angle" is created.
- Each of the grippers can be able to put a product in a range of about 30 to 60 degrees to thereby create a product flow create that has a leading corner configuration. So created for example, a 45 degree turn a configuration of the leading corners, in that the two front sides of the signature form a 45 degree angle with a line, which is perpendicular to the direction of movement.
- the grippers it is also possible to turn only some of the grippers leave while the other grippers remain unrotated.
- the Product stream to be divided so that some of the products become a secondary Product stream can be implemented while some products in the original Product stream remain.
- At least one gripper is with different degrees of rotation intended.
- the gripper rotates in a range of approximately 30 to 60 degrees, to achieve a configuration of the leading corners.
- grippers in a larger range, for example from about 120 to 150 Degrees, thereby rotating an alternative corner to the position of the leading corner.
- a rotating gripper that has a corner on the grips leading edge of a signature stream. With a 45 degree turn one of the corners of the leading edge of the original product stream is the leading Corner. With a rotation of 135 degrees, however, one of the corners becomes trailing Edge of the original product stream the leading corner.
- the individual grippers can be operated individually, so that a whole variety of Product sharing patterns can be achieved, such as sharing or pasting selected products whenever necessary. They are also alignment and division of the secondary product stream ensured because the products of the secondary Electricity does not have to be placed on a vacuum belt, which leads to changes in position the scale formation can lead.
- the products are in the original Product flow conveyed so that it is essentially on one side of the conveyor path extend.
- the products can then work together or selectively to a suitable degree be rotated to the selected products in a configuration with leading Bring corners, and can be essentially horizontal within them extending plane. This reduces compared to conventional ones Systems with the required second belts the space required on the conveyor belt and offers improved transport properties for the rotated product stream.
- a device for stepless Regulation on the side of the funding path will be provided to the products of the to seize and receive secondary current inevitably. After the entry The grippers give the products to the device for stepless regulation free, and are a fixed division and correct alignment for the secondary stream ensured because the products under constant rotation and transfer Are control.
- a similar one Device also implement products that remain in the original product stream.
- a continuous Product transport is achieved by providing individual grippers that span the entire individual funding path are interconnected.
- the individual funding path can be a first, a second, a third or have multiple groups of grippers, with the members of each group being able to be operated individually.
- each gripper comprises a gripper head, which is rotatable about an axis of rotation, and the one movable lower section for Grasping and releasing the products.
- the first actuator can be a first, for example Actuating pin that is connected to a spring drive, a hydraulic drive, a Pneumatic drive or other suitable device for moving the movable lower portion of the gripper head is coupled.
