Abstract: An industrial roll includes: a substantially cylindrical shell having an outer surface; a polymeric cover circumferentially overlying the shell outer surface; and a sensing system. The sensing system includes: a plurality of sensors embedded in the cover, each sensor configured to sense a data parameter; and a plurality of wireless transceivers, each transceiver connected to a respective sensor and embedded in the cover adjacent thereto. Each wireless transceiver is configured to transmit data signals from the respective sensor. Related methods and systems are also discussed.

Abstract: An expander roller includes a tubular roller sleeve 2 adjustable in its curvature that is formed of one-piece tubes made of reinforced plastic/composite material, and that is mounted on a non-rotatable central area by means of bearings 13. The central area is a deformable axis. The outer surfaces of the bearings 13 rest against the inner wall of the roller sleeve 2 or of one of the outer ring shell bushings 3 resting against its inner wall. The inner surfaces of the bearings 13 rest on the upper surface of the deformable axis 1 or of a ring shell bushing 4 firmly surrounding it.

Abstract: Nip press belt of a wet press or a calender with elongated nip, in particular for a paper, cardboard or tissue machine, with a flexible elastomer layer that is impermeable to liquids and with a textile reinforcing layer, wherein the elastomer layer comprises soft rubber with a hardness in the range between 5 and 100 P+J.

Abstract: Nip press belt (9) of a wet press (1) or a calender with elongated nip, in particular for a paper, cardboard or tissue machine, with a flexible carrier layer (9a) that is impermeable to liquids and is made of soft rubber having a hardness in the range between 20 and 50 P+J and an integrated textile reinforcement (9b), and with a covering layer (9c) that is fixedly connected to the carrier layer or formed together therewith.

Abstract: This invention is directed to a method of designing and/or visualizing at least one roll/felt combination in the wet press of a paper or cardboard making machine, wherein initially a press configuration is selected from a set offered by a computer system. Thereafter, one of the presses of the respective press configuration is selected. Thereupon the current dewatering performance of the selected press is calculated and the result if displayed. Thereafter, the machine parameters and/or roll parameters of the respective selected press are altered while the dewatering performance of the respective roll/felt combination of the press is continuously calculated anew and is displayed at least in part as a trend indication.

Abstract: A guide roller for web material, in particular for paper-handling machinery, has two outer tube sections (2, 2′) and optionally at least one tube section (1) arranged between these. The tube sections (1; 2; 2′) are supported on a central shaft (3) through ball bearings (5; 6; 7), and the outer tube sections (2; 2′) are adjustable radially relative to the shaft (3) at their outer ends. The ends (1a; 2a) of the tube sections (1, 2) that are adjacent to each other fit into each other and are connected directly to each other so as to non-rotatable, the ball bearing (5) being situated beneath the area of overlap (1a, 2a) and the outer tube sections (2; 2′) being configured elastically in the longitudinal direction.
