Übersetzung für "Glättwerk" in Englisch

The calender therefore is additionally loaded with pressure.

The paper web 1 to be calendered is guided in a calender 2.

The smoothing nip or the relevant thickness calender can be arranged, for example, within a wire loop.

For this, a so-called calender is particularly suitable.

The calender with the chill section arrangement is shown schematically in FIG. 1 .

The smoothing nip, or the relevant thickness calender, can be arranged, for example, within a wire loop.

The thus coated fabric passes through a calender and then a cooling roller system.

That is why we have developed the Multi-Touch roll stack for high-performance applications.

The Multi-Touch roll stack ensures outstanding sheet quality regardless of the raw materials used.

The Multi-Touch roll stack has already been sold 15 times since its introduction in 2012.

The calender contained the following hard cylinder combination:

For increasing the smoothness of paper it is often necessary to use heated rolls in the smoothing or glazing mechanism.

FIELD OF THE INVENTION The invention relates to a heatable glazing or calendering roll of the type set forth in the preamble of claim 1.

To improve the surface properties, the base paper can be treated with a smoothing device or a calander.

Also, the speed at which the paper web is released towards the calender and pope reel is usually set very low.

Known calibrating and cooling devices comprise, for example, a 3-roll polishing stack with a polishing roll and two cooling rolls.

The polishing calender comes with extensive standard equipment, unparalleled user-friendliness and an attractive price/performance ratio.

Before entering the calender, the assembly to be laminated, comprising the PVC sheet and the fiber-blend web, is applied to the base material, and the heat of the surface-molten base, which is at 190°, suffices partially to melt the polypropylene fibers in the web, which then weld under pressure, in the nip, to the base consisting of wood flour-filled polypropylene.

The crude sheet 6 is then fed, via take-off rolls, optionally to a smoothing unit or abrasive rolls and thereafter guided past the stamping device 9 to mark the rolling direction.

This is done in an attempt to eliminate any irregularities in paper thickness produced in other sections of the paper machine, like variations in weight per unit areas or basis weight produced in the wet section, variations in the moisture of a felt, or variations in dryness over the width of the web upstream of a calender stack.

Production is also possible by extruding in a single-screw or twin-screw extruder with subsequent final forming by means of a polishing stack or calender to give layers of a thickness from about 0.02 to 10 mm, preferably from about 0.4 to 6 mm.

During pressure loading, however, the stacked cylinders in a calender tend to change their position and are laterally displaced.

A particularly level paper surface was obtained in the shown example by additionally drawing the coated paper through a glazing unit with high-polished machine glazing cylinders, thereby pressing the coating slip into the paper.

In such cases the glazing unit is preferably designed in such a way that the raised areas on the calendering cylinder stand out from the remaining areas by only fractions of a millimeter, preferably 5 to 50 micrometers.

In this case one uses a glazing unit in which the areas where the holograms are to be applied are raised above the remaining area by only a few hundredths of a millimeter (preferably 5 to 50 micrometers).
