CA 2132175

The present invention is directed to a roll used for tensioning a canvas belt used to hold paper against a dryer. The roll includes a main cylindrical body formed of steel. A layer formed of a metal harder than steel is disposed over the outer surface of the main body. The metal layer is formed with a channel around its center so as to define two spaced roll end sections of a common diameter. A fluororesin layer isdisposed in the metal layer channel and is shaped so as to have an outer surface of a diameter equal to that of the metal layer end sections.

Les deux extrémités du rouleau sont revêtues d'un matériau plus dur que le matériau de base en recourant à une des méthodes suivantes : chromage, nickelage par placage (non électrolytique), pulvérisation à chaud de cermet d'alliages, etc., et la partie centrale du rouleau est revêtue de plastique tel la fluororésine, de préférence mélangée à l'une des matières suivantes : carbone, fibres de carbone, carbone et graphite, fibre de carbone et graphite, carbone et bisulfure de molybdène, fibre de carbone et bisulfure de molybdène, pour constituer la surface uniforme d'un nouveau type de rouleau destiné à prévenir le problème de formation de résine sur les rouleaux pour toile dans les machines à papier, allonger la durée de vie des rouleaux et résoudre le problème de formation d'électricité statique.
