Abstract
1,050,823. Rollers. BELOIT CORPORATION. Feb. 4, 1964 [Feb. 14, 1963; Oct. 16, 1963], No. 4708/64. Heading F2U. [Also in Divisions D2 and F4] A felt with or without a paper web thereon is passed into a nip between two press rolls, one of which has circumferential grooves in its surface, the grooves having an axial dimension "x" " at the roll periphery of À005-0À35 inch and a radial cross-section of at least twice x<SP>2</SP>, the land areas between the grooves having an average axial dimension of 2À20 times x and a total area of at least 66<SP>2</SP>/ 3 % of the surface area of the roll. The grooves may lie in planes perpendicular to the roll axis, and/or there may be grooves extending helically in one or both directions. There may be axially extending grooves cross-linking the circumferential grooves. There may be blind drilled holes within the grooves. The grooves may be formed in a rubber or stainless steel cover. Straight nip-line, pneumatic loading mounting means are provided for the grooved rolls.
