Method for operating a device for carrying out cutting operations on open format edges of a printed product

A method for operating a device for carrying out cutting operations at cutting locations on at least one open format edge of at least one printed product, the cutting operations comprising a first cutting operation, a second cutting operation, and a third cutting operation, the device being operatively connected to a printed product-based feed apparatus for feeding the first cutting operation and operatively connected to a printed product-based removal apparatus which operates on the printed product after the third cutting operation, each of the cutting operations being carried out using at least one cutting apparatus, the method comprising:

• transferring the printed product from a first cutting location, at which the first cutting operation for a first format edge of the printed product is carried out, to a second cutting location, at which the cutting operation for the second format edge takes place;
• and
• after the second cutting operation is complete at the second cutting location, transferring the printed product to the third cutting location, at which a third cutting operation for a third format edge takes place;
• wherein at least one of the transferring the printed product from the first cutting location to the second cutting location or the transferring the printed product from the second cutting location to the third cutting location is performed by at least one transport unit, the transport unit comprising at least one gripper that grips the printed product by its spine in order to convey the printed product in a suspended manner,
• wherein a plurality of pressure forces act on the printed product at each of the cutting locations prior, during, or following a respective one of the cutting operations, the pressure forces comprising:
• a) a first pressure force on the printed product being exerted by at least one clamping jaw of the gripper in order for the gripper to grip the printed product by the spine in a suspended manner prior to the respective one of the cutting operations;
• b) a second pressure force on the printed product being exerted by at least one first clamping apparatus, the second pressure force acting on the printed product to hold the printed product in a stationary manner during the respective one of the cutting operations;
• c) a third pressure force on the printed product being exerted by at least one second clamping apparatus, the third pressure force acting on the printed product at a cutting region adjacent to a blade during the respective one of the cutting operations, and
• wherein, the first clamping apparatus, of at least the second cutting location, comprises individual pressure bars, and when the pressure bars carry out a pressing movement onto the printed product, the pressing movement thereof begins with a first pressure bar of the individual pressure bars in a spine region of the printed product, then proceeds with successive pressure bars in an order toward a plane of an edge of the printed product to be cut.
