Abstract: A press section apparatus (10) is disclosed for pressing water from a formed web (W). The apparatus (10) includes a press frame (12) and a backing roll (14) rotatably supported by the frame (12). An elongate pressing device (16) cooperates with the backing roll (14) for defining therebetween an elongate pressing section (18) for pressing water from the formed web (W). A looped bearing blanket (20) extends through the pressing section (18) with the blanket (20) being disposed between the pressing device (16) and the backing roll (14) for supporting the web (W) during passage of the web (W) through the pressing section (18). A heater (22) is disposed adjacent to the backing roll (14) for heating the backing roll (14) such that the web (W) extending through the pressing section (18) is subjected to an increased temperature and pressure for an extended period so that water vapor generated within the web (W) during passage of the web (W) through the pressing section (18) drives off from the web (W) water within the web (W) in the liquid phase. The apparatus (10) also includes a felt (30) disposed between the web (W) and the blanket (20) for permitting the water in the liquid phase to be vented from the pressing section (18) and a further felt (32) for absorbing and transporting the water in the liquid phase away from the pressing section (18) so that delamination of the pressed web (W) is inhibited.

Abstract: A method and apparatus for treating pulp prior to being made into paper, which treatment is known as beating or refining. The method comprises feeding a slurry of the pulp to the narrow nips of grooved rolls (14, 15) at which the slurry of pulp is partially dewatered. Then, almost simultaneously, fragments of the pulp are subjected to a predetermined heavy pressure, then dispersed before being subjected to the same sequence until treated to the desired degree.

Abstract: A method is disclosed for reducing the amount of linting generated by newsprint during printing thereof. The method includes the steps of ejecting a slurry of papermaking stock (10) onto a forming wire (12) of a papermaking machine (14). A first portion of water is drained through the forming wire (12) such that a web (W) is formed and supported on the forming wire (12). The formed web (W) is removed from the forming wire (12) onto a press felt (16) where the formed web (W) passes through a press nip (18) for removing a second portion of water from the formed web (W). The pressed web (W) is transferred to a dryer felt (20) of a drying section (22) where the web (W) extends around a plurality of rotatable heated cylinders (24, 25) for removing a third portion of water from the pressed web (W). The dried web (W) is guided through a calender (26) which includes a roll (28) and a further roll (30) counter-rotating relative to each other. The rolls (28, 30) define therebetween a calendering nip (36) for the passage therethrough of the dried web (W). At least one of the rolls (28) is heated to a temperature above 200 DEG C such that at least one of the surfaces (38) defined by the web (W) include strongly bonded fibers due to thermoplastization and flow of fibers within the web (W) so that during printing, the amount of linting by the web (W) is reduced. The disclosure also includes newsprint produced by the aforementioned method.

Abstract: Process and device for automatic tube feed in back-up roll-type reel cutters. A wide web (12) of paper or the like is wound off a wide roll (11) in a take-off station (10). The wide web (12) is divided lengthwise into at least two narrower partial webs (24) in a cutting station (20). The narrower partial webs (24) are wound on using winding tubes (44, 54) in two take-up stations (40, 50) each consisting of at least one take-up device (41, 51) which are arranged on either side of the back-up roll(s) (30), each of the adjacent partial webs (24) being wound onto a different take-up station (40 or 50). The winding tubes (44, 54) are pushed into a feed device (60) into a transfer position parallel to the back-up roll (30) or the back-up rolls in a row one behind the other in association with the empty take-up devices (41, 51), distributed from their transfer positions onto either side of the back-up roll(s) and transported into the tension positions on the take-up devices (41, 51) where they are tensioned so that they can later receive the end of the associated partial web. The winding tubes (44, 54) located in their take-up position and distributed on either side of the back-up roll(s) are taken from the transport device (70) associated with the corresponding take-up device (41, 51) and raised or lowered into the tension position along an essentially rectilinear path. The automatic feed of the winding tubes is thus appreciably improved, because the machinery is comparatively simple, despite the fact that a wide range of adjustments are dispensed with, resetting times are reduced and fewer service staff are required.

Abstract: A screening apparatus comprises a pair of stationary concentric screens with a plurality of foils rotating therebetween and adjacent thereto, the individual foils being radially aligned. The screening apparatus comprises a tangentially disposed slurry inlet and a diametrically and tangentially disposed heavy rejects outlet at the end of a heavy rejects trap. The light reject/accepts slurry flows into the screening zone and, after separation, is discharged at an end of the screening apparatus by way of respective light rejects and accepts outlets. The accept outlet is located axially with respect to the screen cylinders and rotating foils so the pressure pulses are virtually eliminated in the screening process. The apparatus may be constructed for vertical or horizontal rotation of the foils.
