Abstract
The disclosure includes a method for gluing fibrous raw materials, which improves the even distribution of the binding agent on the fibers considerably. The disclosure furthermore describes a device for performing the gluing process. The disclosure suggests a method for moistening fibrous raw materials provided for the manufacture of fiberboards, mats and the like with bonding agents, wherein the fibrous raw materials exist in at least a pre-dried state and are moistened by a pre-dispersed binding agent in a continuous stream, and wherein subsequent to the moistening process the fibrous raw materials are compressed with high pressure before being conveyed further.
Claims5
Method for providing fibrous raw material with a bonding agent, the fibrous material being intended for the manufacture of fiberboards, mats and the like, the method comprising:
- providing a continuous flow of the fibrous material;
- moistening said flow of fibrous material wit a bonding agent;
- compacting the flow of fibrous material in order to provide movement of the fibers against each other so that equalizing of the bonding agent on and between the fibers is achieved;
- and
- conveying said flow of fibrous material to a shaping station in order to manufacture the fibreboards, mats and the like.
