Abstract
A gear folder for folding paper webs or sheets is provided with a cutting knife cylinder, a counter-cut groove cylinder, and a collecting and folding blade cylinder. The collecting cylinder has an odd number of fields for receipt of sheets and further includes an internal folding blade carrier having an even number of folding blades which selectively project through the periphery of the collecting cylinder to transfer a web to suitable folding rollers. Each of the fields of the collecting cylinder is provided with a pin set to retain the web on the periphery of the cylinder. The pin sets are controlled to selectively retract in conjunction with the projection of the folding blades to allow transfer of a selected sheet or stack of sheets to the folding rollers. The frequency of retraction of the pin sets and projection of the folding blades can be varied to transfer the sheets to the folding rollers after each revolution or only after several revolutions of the collecting drum.
