Connection of partial plates of rolling plates in a continuous press

Abstract

The invention relates to a continuous press (1) for producing plates by pressing corresponding material. Said continuous press comprises a press upper part (2) and a press lower part (3) that consists of, respectively, a continuous steel sheet press strip (4), several rolling bodies (5) and a rolling plate (6) that has several partial plates. Press cylinders (7) are arranged in at least one of the press upper parts (2) or press lower parts (3) which, with correspondingly opposite counter means (8), exert a pressure between the rolling plates (6) in the other press upper parts (2) or press lower parts (3). The press cylinders (7) and the counter means (8) are respectively arranged in rows crosswise to the direction of travel (9) of the continuous press (1) on the respective rolling plate (6) and a rolling plate section (10) lies between two adjacent rows of press cylinders (7) or counter means (8). The connection (11a) between two partial plates of a rolling plate (6) is arranged in another rolling plate section (10) as the connection (11b) between two partial plates of the other rolling plates (6).

Description

technical field [0001] The invention relates to a continuous press for the manufacture of boards, especially wood-based boards and laminated boards, by pressing the material. In particular, the invention relates to the joining of sub-plates of rolled plates in continuous presses. Background technique [0002] Continuous presses are used to manufacture boards, such as wood boards, laminated boards, chip boards, fiber boards, etc. In such a press, the material to be pressed, the pressing mass, is pressed continuously between an upper pressing part and a lower pressing part by means of an upper and a lower pressing belt of steel sheets. Here, the steel sheet pressing belt runs continuously around deflection rollers and drive rollers respectively. [0003] In known continuous presses, the sheet metal pressing strip is supported in the pressing zone on rolling plates under an intermediate connection of rolling elements. The rolling plate usually has heating channels with which...

Problems solved by technology

As a result, the pressure is transmitted unevenly to the pressed material, which can lead to undesired loading of the pressed material

Furthermore, due to the insufficient counterpressure of the pressed material, steam emissions can occur on the sides of the press, due to which steam emissions not only soil the machine, but also the dirt discharged in this way increases the fire risk in continuous presses
