  • the invention relates to a method for the gluing of particles, which consist at least partially of fibers and / or chips suitable for the production of material plates, according to claim 1 and to a device for gluing particles, at least partially from suitable for the production of material plates fibers and / or chips, according to claim 9.
  • binder is understood to mean a so-called adhesive liquor which consists of an adhesive in its main component.
  • adhesive liquor which consists of an adhesive in its main component.
  • hardener formaldehyde scavengers, dyes, insect repellent and antifungal agents and other additives are added. It is also common to use the adhesive without additives.

  • US 4,116,163 the chips are thrown after a metering device with a first centrifugal plate against the walls of the chute and with another device in a rotation to form a tubular chip carpet. After this tubular division, the chips are sprayed with a conical spray pattern from the inside out with glue and then thrown on a centrifugal plate radially outward again against the inner walls of the chute. Subsequently, it would be possible to use other mixing devices to intensify the mixing of the glue with the chips.
  • a similar device is for this purpose in DE 203 17 633 U1 shown in the after a metering device in a chute by means of two counter-rotating spiked rollers, the chips are compacted into a particle curtain, which is glued using gluing nozzles with glue.

  • the term "second particle curtain" is understood to mean the formation of a targeted particle stream for gluing by a second dissolving device, in this case the main dissolving device, and not the division of the particles into two or more particle streams by the first dissolving device, here pre-dissolving device, for optimal and in particular uniform charging of the second dissolving device with two or more particle streams.
  • a spiked roller has a variety of spikes or nails or similar shaped body for optimal and targeted promotion respectively dissolution in the axial and radial extent and is driven accordingly with a motor.
