Abstract
The present invention is related to a device for varying a cylinder's effective diameter. It includes a shell member being removably mounted on a surface of a cylinder. On the easy exchangeable shell member having a base plate an elastic material is provided allowing for a compressible surface gain.
Claims19
Device for varying an effective diameter of the cylinder comprising:
- a shell member removably mounted on a surface of the cylinder;
- said shell member having a base plate, a leading edge, a trailing edge, and an elastic material arranged on said base plate allowing for a compressible surface gain;
- and
- a lock-up device, secured in a gap of said cylinder, for securing the trailing edge, including a tensioning member secured on a base, which base pivots about an axis;
- wherein the leading edge and trailing edge are positioned in such a manner providing a gap therebetween;
- and
- wherein the base is biased to pivot about the axis in such a manner that the tensioning member provides tension in at least a direction tangential to the cylinder.

Cutting cylinder comprising:
- a shell member removably mounted on a surface of the cylinder;
- said shell member having a base plate, a leading edge, a trailing edge, and an elastic material arranged on said base plate allowing for a compressible surface gain;
- and
- a lock-up device, secured in a gap of said cylinder, for securing the trailing edge, including a tensioning member secured on a base, which base is biased to pivot about an axis;
- wherein the leading edge is secured to the surface of the cylinder;
- wherein the leading edge and trailing edge are positioned in such a manner providing a gap therebetween;
- and
- wherein the tensioning member secures the trailing edge by providing force in at least a direction tangential to the cylinder.
