摘要： Methods of recycling office waste paper of the type having ink and laser printed thereon. The wastepaper is simultaneously pulped and ink particles dispersed by kneading (2) the waste paper in the form of a high solids content aqueous mixture or sludge. After the simultaneous pulping and dispersing, no additional dispersion step is needed to form deinked paper stock. The high solids content aqueous mixture sludge is diluted and forwarded to wet deinking separation devices such as froth floatation unit (12) or the like. The thus treated pulp is washed (18) and results in the formation of a high quality pulp stock (20) ready for bleaching and/or paper making procedures.

摘要： The invention relates to a screen plate (10), and method of making a screen plate, for the pressure screening of papermaking stock in pressure screening apparatus. The screen plate includes slots (16) which have been cut therethrough by a machining laser beam focused at the inlet side (20) of the plate, to provide slots with nearly straight walls (32) with minimum taper, and which have a recast layer (42) and which have a "glassy" appearance by reason of the melting and resolidification of the immediate wall surface, to provide a very hard and low friction path for the stock. Wear bars (25) are applied to the plate (10) for coaction with the rotating foils on the screening apparatus, in the form of beads of weld material of high hardness applied directly to the plate.

摘要： s7 Apparatus for screening papermaking stock comprises two annular flat screening plates (36, 46) arranged in parallel spaced relation to form a screening chamber (55) therebetween which is bounded on its outer periphery by a cylindrical wall (35). A rotor (15) includes vane portions (60) which extend into this screening chamber to agitate the stock so that particles of sufficiently small size can pass through the screening plates into annular compartments (75) outside the screening plates from which they flow into a peripheral chamber (77) having an outlet port (78). The screening chamber (55) includes an annular space (70) which is surrounded by the accepts chamber, and is radially beyond the vane portions of the rotor, wherein reject material collects for discharge through an outlet tube (71) which extends through the accepts chamber (77) to the outside of the apparatus. The apparatus as a whole comprises a main assembly which includes one of the screening plates and the rotor (15), and a subassembly which includes the other screening plate (46) and can be removed from the main portion to expose the screening plates for replacement or other servicing.

摘要： A continuous winder for web material (W) includes two pairs of turret arms (14, 15) mounted for rotation with respect to each other on a common axis (16), and also includes a lay-on roll (30) mounted for lateral movement toward and away from the axis (16) of the turret arms (14, 15). The lay-on roll (30) maintains pressure engagement with the winding roll (R) until the interval of actual roll changing, when it moves from the wound roll (R) into pressure engagement with the new core (C) with the web (W) running therebetween, whereupon the web (W) is cut between the two rolls (R) to complete the roll change. The knife assembly (50) for cutting the web (W) is carried by another pair of pivotally mounted arms (53) and includes a clamp mechanism (80) on each arm (53) which effects rotatable clamping engagement with the adjacent turret arm (14, 15) carrying the new core (C) so that the knife arms (53) and the core-carrying turret arms (14, 15) travel together throughout the actual operation of roll changing and thereby assure that the knife (52) is held in proper relation with the core (C) before the roll change is made and while it is being made.

摘要： Apparatus and method for thickening a suspension of pulp in liquid employs three rolls (20, 22, 25) arranged in spaced relation with their axes defining a triangle, and a single loop of wire (30) is trained around and in wrapping relation with all three rolls. The first and third roll have a headbox (40, 45) which delivers a flow of the suspension to be thickened in such manner that it is trapped between the wire and the portion of the roll wrapped by the wire so that the trapped suspension is dewatered and concentrated by expression of liquid through the wire. The pulp deposited on the inside of the wire at each of the positions comprising a roll and headbox is collected from the surface of the second roll (22) and is transported out from within the triangular space within the wire loop. In one embodiment, the roll at each roll-headbox station has a grooved surface such that it forms separate strips of pulp on the wire, and the next roll downstream therefrom has a similar grooved surface offset axially from the preceding roll so that it causes strips of pulp to be deposited on the wire between the strips produced by the previous roll.
摘要翻译：用于增稠液体中纸浆悬浮液的装置和方法采用三个辊（20,22,25），它们以与轴线成间隔的方式排列成三角形，并且围绕线圈（30）绕着所有三卷。第一和第三辊具有流浆箱（40,45），其将悬浮液的流动以这样的方式传递，使得它被捕获在线和由线缠绕的辊的部分之间，使得捕获的悬浮液脱水并通过液体通过电线浓缩。在包括辊和流浆箱的每个位置处沉积在电线内部的纸浆从第二辊（22）的表面收集并且在线环内的三角形空间内被输出。在一个实施例中，在每个辊流量计站处的辊具有带槽的表面，使得其在线材上形成分离的纸浆条，并且其下游的下一个辊具有与前一个辊轴向偏移的类似的槽表面，使得其产生带的纸浆沉积在由前一卷产生的条带之间的线上。

摘要： All of the essential operating parts for adding a top former assembly to a new Fourdrinier paper machine or for converting an existing Fourdrinier paper machine into a top former are carried by a supplemental frame assembly (100) which can be mounted on the main Fourdrinier frame (10) with minimal modification of the latter except the addition of simple parts for securing the supplemental frame assembly on top of the main frame. The primary operating parts of the top wire assembly are a hollow open faced roll (125) and a top wire deflector (150) which cooperate to collect and deliver liquid expressed through the top wire (110) into a receptacle (195) that is carried by the supplemental frame assembly, and special provision is made for utilizing the top wire deflector to correct for irregularities in the cross machine profile of the paper sheet as it is being formed. Provision is also made for operating the resulting top former in roll former mode, blade former mode, or a combination roll and blade former modes.
