Abstract: In the paper coating operation a wet or dry edge from coating composition is formed on the, seen in the direction of movement of the paper web, downstream side of the doctor, the so-called stalagmite formation. This stalagmite formation leads to various problems in the papermaking process and especially occurs at high speeds of the paper web and/or a high solids content of the coating composition, which two operating conditions are exactly required to obtain a maximum paper yield and a high paper quality. According to the invention the stalagmite formation is effectively prevented by supplying a fluid inhibiting the stalagmite formation to an area bounded, on the one hand, by the paper web and, on the other hand, by the above side of the doctor blade.

Abstract: The invention concerns a method for regulation of the moisture profile of a paper or board web in a size press in which the paper or board web (W) is made to run through a nip (N) formed by the rolls (1,2) in the size press. Films (F.sub.1, F.sub.2) of size are applied to the faces (3,4) of the rolls in the size press by means of coating devices (10,20) so that these films (F.sub.1 F.sub.2) of size are transferred onto the paper or board web (W) in the roll nip (N). A size (F.sub.1) of substantially invariable profile is spread onto the face (3) of the first roll in the size press (5), and the profile of the size film (F.sub.2) to be spread onto the face (4) of the second roll is regulated so that the moisture profile of the web (W) at the reel-up can be made substantially invariable. The invention also concerns a film size press for implementing the method.

Abstract: A device for coating a web of material, especially a web of paper or cardboard, that travels around a backing roll, with a coating roll that scoops liquid coating from a chamber and demarcates in conjunction with the backing roll a coating nip, and with a flow-control system including a final flow controller and an initial flow controller upstream thereof in the direction that the web travels in and demarcating in conjunction with the backing roll an initial flow-control nip. The device has a non-resiliently supported initial flow controller that extends into the vicinity of the coating nip and demarcates it in the form of a chamber at the outlet end, whereby the initial flow-control nip remains open to the backing roll and to an outflow channel to the coating roll.

Abstract: In a coating device, a doctor blade is bent S-shaped for application of its contact force by means of a pressure bar. An additional force of a profile correction device is exerted for profile correction by means of magnets. This additional force acts preferably opposite to the main contact force. This prevents the profile correction device from causing a change of the geometry of the doctor blade in the contact area of the spreading edge of the doctor blade.

Abstract: A coating device for a material web, such as a paper or cardboard web, is provided. A doctor band, serving as a doctor element, is run over reversing rolls in the form of a loop and along a backing roll that supports the material web. A doctor band drive is provided by take-up drums that can be driven by a motor. The feed of the doctor band is very low, for instance, 2 to 10 cm/min. This provides sufficient time for performing a thorough cleaning of the doctor band. The band may be cleaned by nozzles, scrapers and the like.

Abstract: A paper coating system is characterized by an upstream dip roll applicator that applies an excess layer of liquid coating material onto a surface of a paper web, and an improved downstream doctor assembly for metering and leveling the coating on the web. The doctor assembly includes a doctor blade having a tip extended against and across the web and a shear plate, upstream of the blade, having a surface extending across and defining a gap with the web. An elongate chamber defined between the shear plate and blade extends across the web, and excess coating removed from the web by the blade flows into the chamber. Coating is drained from and uniformly along a lower end of the chamber at a rate to maintain an eddy current pool of coating in an upper end of the chamber immediately upstream of the blade/web nip, but to prevent formation of a liquid seal in the gap. The eddy current pool of coating rewets the excess coating on the web just prior to the blade to level and smooth streaky film split patterns that occur from dip roll application, so the blade doctors the coating very uniformly and a very uniform coating is on the finished paper sheet. To further improve uniformity, the shear plate is adjusted so that the gap is sufficiently small to prevent any outflowing coating from spattering onto the incoming web, yet large enough to prevent formation of a liquid seal in the gap.

Abstract: The doctor device has a profile member pivotally mounted to a retaining member that is carried on a mount. Vertical movement of the mount causes angular displacement of the profile member thereby changing the material applicaton area disposed adjacent and upstream of the doctor. The doctor is either a doctor blade or roll doctor. In the case of a roll doctor, a receptacle is formed in the profile member and the roll doctor is magnetically retained with the receptacle. During application of a material to an application surface with the roll doctor, the roll doctor is magnetically attracted to the application surface by a second magnetic device located beneath the application surface or work surface.
