Abstract

The invention relates to a pressing device (1) for the continuous production cleaning device (6) is arranged at a carrier web (7) that can be driven in a circulating manner by means of a drive (8), essentially in a direction that is transversal to the direction of movement of the press belt (6) wherein a surface pressure is brought onto a chip or fiber mat (2) that is provided with a binding agent between a circulating press belt (5) and a press drum (3) wherein a cleaning device (6) can be brought against the press belt (5) essentially over its entire width. The cleaning device (6) is arranged at a carrier web (7) that can be driven in a circulating manner by means of a drive (8), essentially in a direction that is transversal to the direction of movement of the press belt (6). Furthermore, a working method for the continuous production of chip or fiber boards is disclosed wherein a chip or fiber mat provided with a binding agent is subjected to a line pressure between a press drum and a pressure roller and additionally, a surface pressure between a circulating belt and a press drum, in order to generate a desired raw density, characterized in that at first, a desired nip width between the press drum and the pressure roller is set, and subsequently, the line pressure that determines the raw density is set by a change in the material supply of the chip or fiber web.
