Device and method for gluing fibers

摘要

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).

主权项

1. An apparatus for applying glue to fibers or similar particles for the production of wood-product panels, the apparatus comprising:
a blow-line along which the fibers to be glued are transported in a pressurized-gas stream; a plurality of nozzles that are distributed along, open into and are connected to the blow-line and that spray the fibers transported along the blow-line with glue, the nozzles being configured as multisubstance nozzles for steam atomization by connection to a respective glue-supply line and a respective steam-supply line; a respective glue valve and a respective flowmeter integrated into each of the glue-supply lines; and at least one controller connected to the glue valves and the flowmeters so that the through-flow amount for each glue-supply line can be separately controlled by the respective glue valve such that the sprayed amount can increase or decrease along the transport path of the fibers.
