Abstract
The present invention is related to a roller having a mantle. The mantle is expandable in a radial direction to allow for changes in diameter of the roller. The mantle of tubular shape is provided with a pattern of openings along its circumference.
Claims25
A Roller, comprising:
- a mantle having a tubular shape and being rigid to maintain a constant diameter across its length when expanded;
- supports for adjusting a diameter of said mantle in a radial direction to maintain a constant diameter across its length when expanded;
- and
- a pattern of openings formed along an entire length of said mantle to provide elasticity for expansion of said mantle diameter, wherein the pattern includes openings that extend within the mantle and have no open lateral edges, and openings that have open edges towards lateral edges of the mantle, so that the roller when expanded will expand uniformly and have a uniform diameter along its axial length.

A delivery section of a folder apparatus, comprising:
- tape rollers;
- a mantle included in said tape rollers, having a tubular shape, being rigid to maintain a constant diameter across its length and having a pattern of openings along an entire length of said mantle to provide elasticity for expansion of said mantle diameter;
- and
- supports for adjusting a diameter of said mantle in a radial direction to maintain a constant diameter across its length when expanded;
- wherein
- the pattern includes openings that extend within the mantle and have no open lateral edges, and openings that have open edges towards lateral edges of the mantle.
