Folder and folding cylinder

Abstract

A folder cylinder with an outer circumferential surface has a first section having a first part at the outer circumferential surface of the cylinder and a second section having a second part at the outer circumferential surface of the cylinder, the first section being movable with respect to the second section, the first part being spaced from the second part at the outer circumferential surface in a first operating mode by a gap. A circumferential surface part is attached movably to the second section and defining at the gap part of the outer circumferential surface during the first operating mode. The circumferential surface part is freely rotatable in a radially inward direction with respect to the second section when the circumferential surface part is located at the outer circumferential surface. The circumferential surface part also has a radially extending inclined surface facing the outer circumferential surface for interacting with the first section so as to retract the circumferential surface part beneath the first part.
