Abstract
Abstract A roller for textile or similar machines is made by producing a calibrated tube of predetermined configuration which is permeable to a synthetic plastic material, and then embedding it in the synthetic plastic material so that the latter forms a jacket around the tube and also penetrates interstices of the latter.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
76 words
A roller, particularly for use in textile and analogous machines, comprising a dimensionally stabilized calibrated intersticed tube permeable to flowable material and composed of a plurality of layers of convoluted fiber-glass strip and just sufficient hardened bonding resin to unite said layers into a self-supporting structure; and a jacket of a synthetic plastic material permeating the interstices of said tube and completely coating the exterior and at least partly coating the interior surface of said tube.
Claim 2
Dependent Claim
76 words
A roller, particularly for use in textile and analogous machines, comprising a dimensionally stabilized calibrated intersticed tube permeable to flowable material and composed of a plurality of layers of convoluted fiber-glass strip and just sufficient hardened bonding resin to unite said layers into a self-supporting structure; and a jacket of a synthetic plastic material permeating the interstices of said tube and completely coating the exterior and at least partly coating the interior surface of said tube.
