Embodiment Construction

[0026] The drawings show a bonding device for bonding fibers or similar particles for the manufacture of wood boards, for example fibreboards. Therefore, this bonding device is integrated in a plant for the production of wood panels.

[0027] The fibers are produced, for example, from wood chips in a defibrator or refiner 1 in a known manner. The high steam pressure present in the refiner is used to blow the fibers from the refiner 1 via the fiber delivery line 2 into the blow line 3 , which is also referred to as the “blow-line”. The blowing duct has a smaller diameter, for example 50 mm to 200 mm, preferably 80 mm to 120 mm. The blowing duct 3 can be provided with one or more pressure sensors respectively on the input side and the output side, these pressure sensors are not shown in the figure. A plurality of nozzles 4 are connected to the blowing duct 3 , with which the fibers conveyed through the blowing duct can be sprayed with adhesive. In this exemplary embodiment, t...

Abstract

A device for gluing fibers or similar particles, in particular for the production of wood material panels, for example fiber panels, having a blowline (3) through which the fibers to be glued are transported, wherein there are connected to the blowline a plurality of nozzles (4) which issue into the blowline and by means of which the fibers transported through the blowline can be sprayed with glue, wherein the nozzles (4) are formed as multiple-substance nozzles, for example two-substance nozzles for the purpose of steam atomization, to which nozzles in each case at least one glue feed line (5) and one steam feed line (6) are connected, characterized in that in each case one glue valve (7) and one throughflow measurement device (8) are integrated into the glue feed lines (5), and in that the glue valves (7) and the throughflow measurement devices (8) are connected to at least one control and / or regulating device, such that the throughflow rate for each glue feed line (5) can be separately controlled or regulated by means of the glue valves (7).

Description

technical field [0001] The invention relates to a device for bonding fibers or similar particles, in particular for the manufacture of wood boards, such as fibreboards, which bonding device has a blow-line (Blow-Line) through which the material to be bonded is conveyed wherein a plurality of nozzles leading into the blowing pipe are connected to the blowing pipe, with which the fibers transported through the blowing pipe can be sprayed with adhesive, wherein the nozzles are configured as multi-component nozzles, for example double The component nozzle is used for steam atomization, and at least one adhesive delivery pipe and steam delivery pipe are respectively connected to the nozzle. Background technique [0002] Within the scope of the present invention, wood boards are in particular fiber boards, such as MDF boards or HDF boards, or also LDF boards. In principle, however, particleboard is also included and thus a bond made of chips or similar particles. Bonding means s...
