Device for seizing of flat material on a transporting surface

A paper conducting assembly in a folder apparatus, comprising:

• a first cylinder having a circumference and knife assemblies assigned to the circumference;
• a paper conducting cylinder having an outer circumference and supporting a flat material on the outer circumference;
• a biased product seizing element assigned to the circumference of said first cylinder engaging said flat material on said outer circumference so as to hold the flat material on the paper conducting cylinder;
• and
• at least one product gripper attached to the paper conducting cylinder for rotation therewith, the product gripper selectively extending beyond the outer circumference of the paper conducting cylinder to hold the flat material against the outer circumference.

A pinless folder apparatus for processing a flat material comprising:

• a first cylinder having a circumference and having knife assemblies assigned to the circumference;
• a paper conducting cylinder having an outer circumference and supporting a flat material on the outer circumference;
• a biased product seizing element assigned to the outer circumference;
• and
• a biased seizing element assigned to the circumference of the first cylinder adopting an engaging position upon cooperation with said flat material received on said outer circumference.

A method for holding a flat material in a folder of a printing press on different supporting surfaces comprising the steps of:

• supporting a leading edge of a web of material on a first supporting surface of a paper conducting cylinder with a biased product seizing element in a first engaged position, the biased product seizing element being on another cylinder cooperating with the paper conducting cylinder;
• having a product seizing element adopt a first disengaged position upon entry of the web of material in a cutting area;
• and
• gripping the leading edge with a gripper while the biased product seizing element is in the first engaged position, the product gripper extending beyond an outer circumference of the other cylinder to hold the leading edge against the outer circumference.

A device for seizing a flat material on a transporting surface comprising:

• a first cylinder having a surface and having knife assemblies assigned to the surface;
• a paper-conducting cylinder having an outer circumference and supporting a flat material on the outer circumference;
• and
• a biased engaging bolt assigned to the surface, the biased engaging bolt adopting an engaging position upon cooperation with said flat material received on the outer circumference;
• and
• at least one product gripper attached to the paper conducting cylinder for rotation therewith, the product gripper selectively extending beyond the outer circumference of the paper conducting cylinder to hold the flat material against the outer circumference.
