Abstract
A hollow cylinder is provided on its interior surface with an annular array of a plurality of annularly spaced, longitudinal ridges. The ridges are held in place by at least one inner support disposed inside the cylinder. A respective longitudinally extending bar is disposed radially inwardly of each ridge and springs bias the bar radially inwardly. The bars engage the support ring. The resultant resilient connection between the support ring and the ridges urges the ridges against the interior surface of the shell. The inner support ring may be constructed of several joined arcuate segments.

A cylinder for use in paper making machines, or the like, comprising:
- a hollow cylinder having an inner surface;
- a plurality of ridges extending in the longitudinal direction of said cylinder, applied against said inner surface of said cylinder and annularly arrayed in spaced apart relationship around said inner surface of said cylinder;
- a common support in said cylinder for all said ridges;
- a respective bar extending longitudinally of said cylinder and interposed between said common support and each said ridge;
- each said bar being in engagement with said common support;
- a plurality of resilient connections at longitudinally spaced apart locations between each said bar and a said ridge where that said bar is interposed between said common support and that said ridge for resiliently urging said ridges in a direction radially outwardly of said cylinder;
- said common support restraining motion of each said bar radially inwardly with respect to said cylinder.
