Abstract: An apparatus and method for use in a batch digesting process to quantitatively displace fluids in the digester (10) by pumping into the digester (10) under pressure a first volume of displacing fluid at the upper end (22) and a second volume of displacing fluid at the lower end (21) of the digester (10). Displaced fluids are collected and removed from the digester near the midline (25) between the top and the bottom of the digester.

Abstract: Apparatus for transferring a newly formed paper web (W) from the forming fabric (16) over a couch roll (38) in a papermaking machine includes a transfer roll (60) which guides a pick-up felt (F-P) into nipping engagement with the paper web (W) over the couch roll (38). The nip (N-P) is located intermediate the circumferentially spaced ends of a vacuum zone (68) on the surface of the couch roll (38). The web (W) with the forming fabric (16) on one side and the pick-up felt (F-P) on the other side is guided onto the transfer roll surface by the forming fabric (16) downstream of the nip (N-P) and is transferred onto the pick-up felt (F-P). The transfer roll (60) has a vacuum zone (68) located downstream of where it is wrapped by the forming fabric (16). The application of pressure on the web (W) over the couch roll (38) prior to, and in conjunction with, the nip (N-P) operates to further dewater the web (W) as well as to facilitate its transfer to the pick-up felt (F-P).

Abstract: A coater apparatus (10A) is disclosed for applying a primary flow (36A) of coating material to a moving web of paper (WA). The apparatus (10A) includes a frame (12A) and a first and a second guide roll (38, 40) rotatably supported by the frame (12A). The first and second guide rolls (38, 40) rotate respectively around first and second rotational axes (42, 44). The second axis of rotation (44) is disposed spaced and parallel relative to the first axis (42). A backing blanket (46) extends around and is guided by the guide rolls (38, 40). The blanket (46) defines an endless loop around the guide rolls (38, 40) such that the web of paper (WA) is supported by the blanket (46) during movement of the web (WA) from the first guide roll (38) to the second guide roll (40). The blanket (46) is disposed between the web (WA) and the guide rolls (38, 40). A short dwell coater (14A) is disposed adjacent to the web (WA) and between the guide rolls (38, 40) for applying the primary flow (36A) of coating material to the web (WA). While the web (WA) supported by the blanket (46) is moving between the guide rolls (38, 40), the web (WA) is moving in a plane (P) disposed tangentially relative to the guide rolls (38, 40) such that secondary flows within the coater (14A) are inhibited.

Abstract: An improved pressure washer (10) and process are disclosed for washing cellulose pulp, wherein a mat of pulp (113) is provided on a rotating drum (40) and moves through a washing zone (54) and a dewatering zone (56) between the mat formation zone (50) and a mat removal zone (52). A hood (20) is provided over the drum (40), with appropriate seals, and a pressurized atmosphere is provided in the washing and dewatering zones (54, 56). To relieve the pressure which normally builds up inside the washer drum (40), a conduit (120) is connected between the drum interior (112) and the inlet (86) of the blower (84) used for pressurizing the hood. In this way, foam generation is minimized as the drum interior (112) is maintained at or below atmospheric pressure. A take-off roll, or doctor, is provided for removing the mat from the drum (40).

Abstract: A resilient metering blade (18C-E) is disposed downstream relative to the application of coating material onto a web (10C-E), e.g. paper. The blade (18C-E) includes a metallic layer (50) having a distal end (52) disposed adjacent to the web (10C-E) and a compressible layer (54), e.g. rubber which is disposed contiguously and upstream relative to the metallic layer (50). The compressible layer (54) has a distal end (56) such that during use of the apparatus (14D, E), as the distal end (52) of the metallic layer (50) wears away, the distal end (56) of the compressible layer (54) is compressed by the coating so that a wedge (38C) of the coating is disposed between the web (10C-E) and the blade (18C-E) thereby maintaining a smooth application of the coating onto the web (10C-E) and a prolonging of the life of the blade (18C-E).

Abstract: A blow box (40) which is disposed within a pocket (26) defined by a web (W) and felt (F) travelling together from a first dryer (12) to and around a second dryer (14) and onto and around a third dryer (16). The blow box (40) includes a wedge-shaped box extending from between the first and third dryers (12 and 16) to adjacent the second dryer (14), the box (40) being connected to a source of pressurized air (42) for maintaining the web (W) in close conformity with the felt (F) when the web and felt diverge relative to the first dryer (12). The box (40) defines an orifice (44) which is disposed adjacent to the first dryer (12) for directing pressurized air against the felt and then redirecting the air in a direction opposite to the direction of rotation of the first dryer (12) such that the web is urged against the felt for inhibiting the tendency of the web to adhere to the first dryer (12) when the felt diverges relative to the first dryer (12).

Abstract: Fines are separated from pin chips and a system in which a mixture of fines and pin chips is introduced onto a rotating disk (38) which imparts centrifugal forces thereto for separation. In a first embodiment, the fines and the pin chips are propelled over different length paths to fall into separate collectors (24, 26), the fines collector (26) entraining the fines into an air stream for disposal. In this embodiment, the rotor (38) comprises a rotary disk having a smooth upper surface, while in a second embodiment the upper surface is provided with a plurality of vanes (42) on the upper surface thereof. In a third embodiment, the rotary disk is provided with a plurality of grooves (68) for directing the fines over the periphery of the disk into its collector. In a fourth embodiment, the rotary disk is provided with a plurality of generally radial slots (82) with vanes beneath in order to provide a classification between fines and pin chips.
