Embodiment Construction

[0056] figure 1 It is a side perspective schematic view of the wetting system 1 of the press 100 for compressing the material block 200 mixed with the binder in the present invention. The moistening system 1 is arranged in the vicinity of a transfer unit 300 of a press 100 through which the mass of material 200 is fed into the press 100 . The press 100 may be any optional press for producing composite panels, typically formed by a press path constituted by a press belt and a release agent coating device arranged before the press path.

[0057] The wetting system 1 of the invention is used to introduce moisture to the block 200 of material. The moisture is used to generate a burst of steam at a temperature of typically about 250° C. in the vicinity of the press belt, wherein the burst of steam penetrates and spreads throughout the mass of material. Thus, heat is transferred to the interior of the block of material, facilitating the curing of the adhesive within the block of m...

Abstract

The invention relates to a press (100), preferably a continuously operating press (100), for compressing a mass (200) of material mixed with a binder, in particular a press for producing composite panels, preferably engineered wood panels The wetting system (1) comprises a first wetting agent application device. The first dampening agent application device (3) comprises: a first application roller (7) which can be arranged from above against a mass of material conveyed by the conveying unit (300) of the press; At least one first dosing roll (9), which can be positioned against said first applicator roll (7); and a first dampening agent tank (11). The at least one first dosing roller (9) is immersed in the first wetting agent tank (11) to bring up the sizing agent, and the at least one first dosing roller includes at least one wiping roller (13), The at least one wiping roller can be arranged against each first dosing roller (9) and by means of the wiping roller the amount of dampening agent carried up by each first dosing roller (9) can be adjusted.

Description

technical field [0001] The invention relates to a wetting system for a press, preferably a continuously operating press, for compressing blocks of material mixed with a binder, in particular for the production of composite boards, preferably engineered wood boards. [0002] The invention further relates to a continuously operating press with such a dampening system, as well as a method for producing compressed composite panels and a wetting agent for the production of composite panels. Background technique [0003] For presses producing composite panels, it is known to moisten a block of material during or immediately before compression in order to penetrate the material by a vapor burst, thereby transferring heat to the interior of the block to accelerate the adhesive Freezes inside a block of material. [0004] From EP1508414A2 it is known, for example in presses, to apply steam to one side of a block of material, where it is attempted to introduce only as little steam as...
