Definitions

  • the invention relates to a process for the continuous production of chipboard, fiber and the like, in which a nonwoven formed on a base of lignocellulosic and / or cellulosic chips, fibers and the like mixed with at least one binder in a calender press with one part its circumference is pressed with heating by a steel belt spanned over guide and pressure rollers, heated and is discharged in the form of a plate strand.
  • a method of this type is known from DE-AS 21 26 935 for the production of uncut chipboard with a smooth surface.
  • the respective fleece is compacted to a smaller thickness than the desired final thickness at the start of the pressing and then pressed to the desired final thickness.
  • the object of the invention is to further improve the quality of the respective strand of plates to be produced, at the same time to reduce the consumption of binder and to achieve an increase in performance.
  • the fleece is compressed at the beginning of the press nip, preferably compressed to a value in the range above or below the nominal thickness of the finished plate or a value significantly below it, and then enclosed between the heated press drum and steel belt with simultaneous further transport is heated until the particles are continuously converted into their elastic state and the binder on the required curing temperature is brought and that at least one additional circumferential position of the heated press drum at least one additional pressure exerted on the steel strip and thus on the nonwoven fabric under the radial holding pressure of the steel strip, and then the nonwoven is cured to a finished pressed sheet strand.
  • a surprising improvement in quality combined with a reduction in binder consumption is - in contrast to the known - the result of the fact that, on the one hand, no excessive pressures are used, but preferably only the pressures absolutely necessary to achieve the final thickness of the respective sheet strand, and on the other hand, additional pressure is only applied to the steel strip then takes place when the best possible effects of this pressure application arise according to the fleece temperature.
  • the steel strip is preferably heated from the outside by contact and / or radiant heat. This makes it possible to achieve a well-dosed heat effect on the steel strip and thus also a heating-up temperature gradient in the respective fleece, which ensures that at every point where additional pressure is exerted, the most favorable temperatures for exerting pressure are present in the fleece.
  • pre-compress and / or preheat the nonwoven before entering the press nip the preheating preferably being carried out using high-frequency energy.
  • the additional pressure is applied to at least two circumferential positions of the heated press drum. then these additional pressure exercises are carried out simultaneously, the additional pressure applied preferably being selected to be of different sizes.
  • a line-shaped and / or planar pressure force transmission is expediently used for the additional pressure exertion, with a choice being made between these two types of transmission depending on the pressure exertion most favorable at the respective point and the heat transfer required.
  • heated rollers are used for the additional application of pressure, then these rollers are preferably brought to a temperature which is between the temperature of the input-side pressure roller and the temperature of the press drum.
  • the method according to the invention is also ideally suited for the continuous production of laminates from being joined together Denden film webs, in particular for the production of technical laminates, such as are required in large quantities in the electrical and electronic industry as circuit carriers and the like.
