Method and device for moistening fibrous raw materials with binding agents
View Patent ↗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.
1. 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.
2. Method pursuant to claim 1 , further comprising providing a plurality of flows of the fibrous material to be provided with said bonding agent.
3. Method pursuant to claim 2 , further comprising moistening separately each of said plurality of flow of the fibrous material with said bonding agent.
4. Method pursuant to claim 2 , further comprising forming a single flow of fibrous material provided with said bonding agent from said plurality of flows of fibrous material to be provided with said bonding agent.
5. Method pursuant to claim 2 , further comprising forming a single flow of fibrous material provided with said bonding agent during the compacting the flow of fibrous material.
