摘要： A doctoring device for an apparatus designed to apply a liquid or viscid medium onto a moving base surface includes a metering unit having a coater rod and a coater rod bed. The metering unit is attached to the support beam and is positioned so that it can be pressed against the base surface. A pressure-elastic support arrangement is disposed between the coater beam and the coater rod bed. The coater rod bed is supported pressure-elastically by the support beam via the support arrangement in at least two support directions that are perpendicular to each other. The spring rate of the support arrangement is adjustable in at least one of the support directions. A preferred support arrangement includes pressure hoses which are assigned to each of the two support directions. The pressures in these hoses can be adjusted, independently from each other, to a pre-determined level via a pressure source. Unwanted deformation of the support beam in various directions relative to the base surface can thereby be compensated for. Furthermore, there is a large degree of freedom in the selection of the mounting position of the doctoring device relative to the base surface.

摘要： The invention relates to a method for roll cooling in paper machines with soft smoothing mechanisms. The object of the invention is to protect the soft roll from damage without having to increase the extent of edge trimming of the paper web. This is achieved in that the parts of the soft roll which respectively project beyond the width of the paper web are cooled by the application of a thin and sharply bounded water film. The corresponding devices for generating the water films are mounted in carriages which are displaceable along a transverse beam parallel to the roll.

摘要： Calendering takes place in a calendering zone which operates under pressure with application of temperature and moisture. The desired smoothness is achieved with a correspondingly long dwell time of the material web in a correspondingly long calendering zone in view of the speed of web travel. A web which is still wet is guided between parallel heatable surfaces which are arranged on both sides of the web and face each other through the web and can each be pressed against the web. The surfaces are designed to form and hold a given precise contour of the calendering zone over its full length. One surface is constructed e.g. as a casing of a heated roller and the second surface is constructed as an endless flexible belt which can be pressed in a direction towards the roller casing by means of a concave supporting element. If wished, the web can be calendered on both sides with the method.

摘要： To achieve desired treatment results at both sides of a material web to be calendered, the material web is initially guided through a first nip formed between yieldable elastic surfaces confronting the throughpassing material web. In the first nip there is predominantly applied a relatively high pressure to the material web. Then the material web is guided through a successively arranged second nip formed between practically non-yieldable hard surfaces confronting the throughpassing material web. In the second nip there is applied, apart from pressure, in particular heat to the material web. The treatment result achieved in the first nip, namely the smoothness and glaze values of the treated material web, are augmented at both sides of the material web to achieve desired treatment effects.

摘要： In a headbox system for a papermaking machine with an adjustable distribution of the fiber stock suspension or pulp over the web width, the flow in the delivery slice is controlled in such a way that, across the web width, also the distribution of the fibers in respect of fiber orientation and quantity has a desired profile. For this purpose, the flow of the fiber stock suspension is controlled such that in the event of a change in the distribution of the fiber stock suspension across the web width, the horizontal component of the flow direction in the delivery slice remains, at all locations, always in the predetermined machine direction and thus transverse flows are avoided and the flow rate in the delivery slice has a predeterminate profile.

摘要： The papermaking machine contains at least one water pervious dewatering wire or the like for forming a fiber web, particularly one layer of a multi-ply fiber web, and at least one headbox for infeeding a fiber stock suspension to be applied in the form of a free jet to the dewatering wire. Between the headbox and a section of the dewatering wire extending along the headbox there is arranged at least one deflecting device for separating and withdrawing a partial flow or stream of the fiber stock suspension. The deflecting device can be inserted into a marginal region of the free stock jet. Such an arrangement enables, for example, a continuous or infinitely variable adjustment of the format width of the fiber web to be produced. During use of the deflecting device, the partial flow or stream of the stock is deflected prior to the formation of the fiber web and is kept away from the following operational or working sections of the papermaking machine, in particular from a second fiber web or ply located thereat. If desired, the deflected partial stock flow can be returned to the fiber stock suspension supply or infeed system preceding or upstream of the headbox for re-use of the unmixed fiber stock material.

摘要： A headbox contains a nozzle channel which, in the direction of flow of the stock suspension or pulp. converges towards an outlet gap or slice. The nozzle channel contains two lips. At least one of these lips has a wall portion or section which is concave with respect to the stock suspension. This wall section is defined by imaginary curved reference lines. This wall section or portion is formed by steps or step portions extending essentially parallel to the outlet gap. Each of the step portions comprises a substantially planar partial surface extending comparable to the direction of flow of the stock suspension and an end surface disposed transversely with respect to its related planar or flat partial surface. At the region of this particularly simple to fabricate wall section there is thus produced microturbulence directly prior to the sheet formation. Such microturbulence ensures for a uniform formation of the stock fibers which are suspended at the region of the marginal flow or boundary region of the stock suspension.

摘要： A pulp feed for a papermaking machine, comprising a substantially slot-like guide channel having at least two step-like widened portions. Before and after each widened portion there is provided a linear channel section, and between the widened portions there is arranged a tapered section or portion. The slot widths before both of the widened portions can be of the same magnitude and conjointly adjustable by means of a translationally movable element. The slot-like guide channel has arranged forwardly thereof a perforated plate and a mixing chamber merging thereat. Also a pulp feed channel having an adjustable lip and merging at the guide channel can possess step-shaped widened portions.
