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. |
