Problems solved by technology

[0009] Furthermore, in practice, in continuous presses, the problems arising from the structure passing through the form of the frame structure of the press frame have been solved, since pressure fluctuations can be caused, causing the glue bridges already formed to snap off again
This may cause a loss of strength in the manufacture of timber panels

Embodiment Construction

[0034] exist figure 1 shows a continuously operating press for the production of wood panels, in particular fiberboard or particleboard. In the continuous press, a mat of pressed material consisting of glued wooden particles, for example glued fibers, which enters the press in the working direction (A) is continuously pressed into wooden material boards or wooden material boards chain. The press has a press frame 1 . In the upper part of the press an upper pressing plate 2 is arranged and in the lower part of the press a lower pressing plate 3 is arranged. The individual press plates 2 , 3 are designed to be heatable, and thus as heating plates. The press frame 1 is composed of a plurality of press frames 4 arranged in a row in the longitudinal direction of the press. Furthermore, the press has an upper entry plate 5 arranged on the entry side in front of the upper press plate 2 and a lower entry plate 6 arranged on the entry side in front of the lower press plate 3 . The...

Abstract

The invention relates to a method for pressing a pressing-material mat (M) in the course of the production of wood material panels, in a continuous press, wherein the press has a press frame (1), a heatable upper press plate (2) and a heatable lower press plate (3), wherein, in order to set a pressing gap between the press plates, the upper press plate (2) and / or the lower press plate (3) is actedupon by pressing cylinders (7) supported on the press frame (1), and wherein the press has a heatable upper inlet plate (5) arranged before the upper press plate (2) on the inlet side and has a heatable lower inlet plate (6) arranged before the lower press plate (3) on the inlet side, wherein, in order to set an inlet gap between the inlet plates, the upper inlet plate (5) and / or the lower inletplate (6) is acted upon by inlet cylinders (8) supported on the press frame. The method is characterized in that the upper inlet plate (5) and / or the lower inlet plate (6) is designed or set to be wave-shaped in such a way that the pressing-material mat (M) passes through a plurality of pulsatingly varying compression phases in succession in the working direction (A) in the inlet gap.

Description

technical field [0001] The invention relates to a method for pressing mats of pressed material in a continuous press during the manufacture of wood panels, [0002] Wherein, the press has a press frame (for example, a plurality of press frames arranged in succession), a heatable upper pressing plate and a heatable lower pressing plate, the upper pressing plate and / or the lower pressing plate The extrusion plate is loaded by means of the extrusion cylinder supported on the press frame to adjust the extrusion gap between each extrusion plate, [0003] And the press has a heatable (preferably flexurally elastic) upper entry plate arranged on the entry side in front of the upper compression plate and a heatable (preferably flexurally elastic) lower entry plate, said upper and / or lower entry plate being loaded by means of entry cylinders supported on the press frame, in order to adjust the entry gap provided between the entry plates (and preferably reduced in the working direction...
