Abstract: A headbox for a papermaking machine with an outlet slot that distributes pulp suspension over the, working width of the papermaking machine. For controlling operating parameters of throughput, pulp density and fiber quality of the suspension over the width of the machine, the headbox has a plurality of individual sections across the width of the machine. Each section has respective channels therethrough for passing pulp suspension. At least one connection at each section is to a controllable supply of pulp suspension where the operating parameters of that supply are controllable. Only separate operating parameter controlled streams pass through the sections of the headbox. Operating parameter control devices may deliver adjusted streams to a mixer upstream of the headbox channels. The mixer may also have individual sections across the width of the machine.

The system includes a tank with a substantially bell-shaped, or flared, interior, the flaring of the tank surface combining with force of gravity to detach frozen material for dispensing. Separate temperature control sections allow selected areas of the tank to be heated or cooled as necessary, moreover, and distinct reservoirs of heat-transfer liquid (such as glycol) may be used for heating versus cooling the tank.

Abstract: A method of processing recycled paper which contains such a high amount of wax, hot melts or stickies that they would be expected to cause a stoppage of the paper-manufacturing machine. The paper to be recycled is pulped in a pulper and passed on to respective subsequent stages which include a despecker, grader and hydrocyclone. Pulping takes place at a temperature of at least 60.degree. C., and at the same time subjects the paper to a high shear action. The processing line includes a pulp-thickening stage, preferably after the processing stages mentioned, in order to separate off a very high proportion of the wax, hot melts and stickies finely dispersed in the pulper.

Abstract: A coating system for material webs, specifically of paper or cardboard, includes two mutually parallel rolls directly coordinated with each other, the rolls having a mutually variable spacing such that the rolls can be positioned to create a press gap for coating the web, or so as not to create a press gap. When the rolls are not positioned to form a press gap, the web passes over both roll shells while circumventing the applicators which have already dosed the roll shells with a coating mixture. The web passes over both roll shells for purposes of transferring the coating mixture predosed by the applicators. Solely the web pull in conjunction with the wrap angle of the two roll shells serves the final dosing by scraping off an excess quantity from the roll shells.
