Abstract: For the application of a coating material onto a running material web, particularly a paper or cardboard web, a cylinder guides the web of material while a dosing element extends over the work width and has a surface which together with the cylinder forms an application gap converging in the travel direction of the web. In order to be able to apply various coating materials at high web speeds evenly and without disturbances, even at low application weights, the dosing element is supported swingably about an axis parallel to the cylinder, the radius of its surface guiding the coating material increases continuously in the travel direction of the web up to the dosing line and the surface ends at the dosing line with an edge whose radius is less than 8 mm.

Abstract: In a drying process for increasing the filling power of tobacco material, the cut and moistened tobacco material is conveyed in a drying gas flow, dried within a tubular drying section and subsequently separated from the drying gas. The drying gas has at a feed point into the drying section a temperature of at least 200.degree. C. and a flow velocity of at least 30 m/sec. The flow velocity of the drying gas is reduced in the drying section. The flow velocity of the drying gas at the charge point into the drying section is at the most 100 m/sec. Within the drying section, to reduce the local heat transfer coefficient and the local mass transfer coefficient between the surface of the tobacco material and the surrounding drying gas, along with the reduction of the flow velocity of the drying gas, the flow velocity of the tobacco material is also reduced. At the end of the drying section the drying gas has a flow velocity of at the most 15 m/sec and a temperature of at the most 130.degree. C.

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 device for coating webs of material traveling over a backing roll to a controlled thickness, in which the coating material can be applied to the web with a slotted nozzle that extends over the total width of the web and in which the nozzle has an initial-flow regulation gap downstream of which a flow-regulation lip and an excess-removal lip demarcate a flow-regulation chamber. To allow more uniform and higher-quality application of the coating medium and, in particular, to ensure heavier coating weights and improved web printability with simple means, a barrier that demarcates the flow-regulation chamber from the traveling web of material is positioned to the vicinity of the excess-removal lip. The barrier can consist of a knife-like sheet-metal spring, of a roll, of a strip, or of a jet directed opposite to the direction in which the web is traveling. The barrier prevents an isolating layer of air from penetrating into the flow-regulation chamber.

Abstract: A device for coating continuous webs with regulable coating strength by means of a doctor rod that rests against the coated side of the web, that is mounted in a doctor bed, and that can be elastically forced with regulable pressure against the web being coated. The doctor rod is a doctor batten that moves with little friction along at least one overflow-side slide face of a rigid doctor bed. The face of the doctor batten toward the web that is being coated is rectangular and demarcates in conjunction with the web a narrowing coating-material application gap with a geometry that depends on the degree of contact pressure. The upper edge of the face constitutes a straight and sharp stripping edge. The face and stripping edge of the doctor batten are flexible. Its face is highly resistant to wear. The contact pressure is exerted by an inflatable means of exerting pressure positioned between the batten and the bed.
