Abstract

Improvements in the patent of invention No. 305,227 by improvements introduced in the rollers to obtain a controlled pressure of the clamping line comprised between a pair of rollers, and more particularly, improvements in the deflection rollers to maintain a uniform contact pressure to along the contact area with a second roller, especially for use in the wet press of papermaking machines, in calenders or in similar machines comprising a cylindrical roll envelope supported rotatably at its ends by means of a shaft fixed central that extends through this envelope, the central axis carrying means to compensate for the flexure of the roll envelope produced under load, characterized in that the envelope (13) of the roller has sleeves (19, 20) provided with fixed flange and protruding from each end of this envelope, the sleeves respectively being supported It is of bearing (25, 26) to rotate about a horizontal axis, the fixed central axis (15) extending through the envelope (13) of the roller and beyond the opposite ends thereof being supported on its end portions opposite (36, 49) by means of self-aligning ball bearing (33, 50) in such a way inside the sleeves (19, 20) fixed to the housing that the flexing of this central axis with respect to its bearing means is compensated by the contact correction pressures exerted on the envelope.
