Abstract
The gluing apparatus (220) for plants for producing wood fibre panels by a dry method comprises a tubular body (250) and sprayer means (262) to inject a suitable liquid glue into the interior of the tubular body (250). The cross-section through the tubular body (250) encloses an area which increases in progressing from its open upstream end (253), into which the wood fibres are fed conveyed by an air stream, to its open downstream end 257). The tubular body (250) comprises a sealed outer wall (252) and an air-permeable inner wall (254) spaced from the former (242). In the outer wall (252) of the tubular body (250) there are provided a plurality of apertures distributed along this latter to enable additional air streams to be fed (through 258) into it.

A gluing apparatus (22) for plants for producing wood fibre panels by a dry method, comprising a tubular body (250) and sprayer means (262) to inject a suitable liquid glue into the interior of the tubular body (250), wherein a cross section of the tubular body defines an area which increases progressively from an open upstream end (253) of said tubular body, into which the wood fibres are fed conveyed by an air stream, to an open downstream end (257) of said tubular body, the tubular body (250) comprising an outer wall (252) and an air-permeable inner wall (254) spaced from the the outer wall (252), the outer wall (252) of the tubular body (250) having a plurality of apertures for enabling the introduction of additional air streams into said tubular body.
A gluing apparatus for plants for producing wood fiber panels by a dry method, comprising:
- a substantially tubular body having an open upstream end into which wood fibers are fed by an air stream and an open downstream end, the cross-sectional area of said tubular body increasing in the direction from the upstream end to the downstream end, said tubular body including
- sprayer means for injecting a suitable liquid glue into the interior of the tubular body;
- an outer wall having a plurality of apertures;
- and
- an air-permeable inner wall spaced apart from said outer wall;
- and
- means for injecting air through the apertures in said outer wall.
