Abstract: On a coating device, at the mouth originating from the chamber for the coating substance, there is provided, between said mouth and the backing roll or web, a cover body which on its surface near the mouth forms an outlet channel that extends away from the space through which at the doctor blade flows the coating substance. This outlet channel has a throttle effect. Additionally, the cover body forms relative to the doctor blade a second throttle channel which is located relatively close to the smoothing edge of the doctor blade. At the outlet of the second throttle channel, the cover body preferably extends into a point which is arranged relatively close to the backing roll or web. The outlet channel can suitably be formed between a base body and the cover body, with the base body ending at a distance from the doctor blade that is maximally 10 mm greater than the clearance of the second throttle channel.

Abstract: A coater for coating a running paper or carboard web comprises a coating chamber having one side open against the web and means for filling the coating chamber with pressurized coating substance. The coating chamber is limited in the longitudinal direction of the web by a web entrance wall, and opposite thereof, a back wall in the form of a doctor member for forming a coating layer on the web. The distance between the walls is so short that, at normal web running speed, the web moves from the web entrance wall to the back wall in a time of at the most 0.3 s, preferably at the most 0.03 s. Coating substance is supplied by means of positive pressure to the coating chamber at a position close to the web entrance wall. Close to the web entrance wall the flow of coating substance in the coating chamber is divided into two branches, of which a first branch follows the web in its running direction towards the back wall and a second branch, which is considerably greater than the first branch, flows out from the coating chamber through a slot between the web entrance wall and the web.

Abstract: Coating apparatus is provided for use in coating a sheet of goods which is carried on a counter-roller. The coating apparatus includes a coating zone which is formed along the sheet to be coated. At least one deflector is provided in the coating zone for deflecting the return flow of coating material deflected at the coating blade to a divergence angle of less than 90 degrees relative to the emerging flow of fresh coating material from the outlet port of the chamber containing the coating material. In general, angle of divergence between the two opposing flows of coating material is less than 60 degrees. In this manner, the amount of agitation and turbulence in the flow of material is minimized.

Abstract: The invention relates to a method and an apparatus for continuously applying a uniform coating to a material web (5), in particular a paper or cardboard web, travelling over a back roller (6), to which the coating material is applied at low pressure by means of a coating roller (2) and with guidance by a guide plate (8) into the coating gap (7) formed by the back roller and the coating roller, whereupon the coating material is metered by a metering member (15) and in the region of a layer close to the material web is partly drained in order to form a barrier layer and final metering takes place in a final metering device (23) by means of a final metering member (24) with low contact pressure. Due to a three-stage method of this type and the apparatus suitable therefore, even at comparatively high material web speeds, constant good coating qualities can even be achieved with extremely low coating weights.

Abstract: A rotary converting machine gum box is replenished with adhesive by means of a pumped circulation system which includes a first pump delivery conduit at one end of the gum box and a second pump suction conduit at the other end. A small adhesive pond or trough region between the two gum box ends carries the adhesive flow from one end to the other parallel to the meter roll surface and in flooding contact therewith. Adhesive pond level within the gum box is regulated by a speed differential between the two pumps thereby regulating the relative supply and withdrawal rates of the two pumps.
