  • Method for the treatment of the steel belts of a double belt press
    Patent number: 5224367
    Abstract: In a double belt press, in which the steel belts are supported on the back by rollers, inherent compressive stress occurs on the side of the steel belts of a double belt press that are supported on the back by rollers, resulting in an undesirable bowl-shaped deformation of the steel belts. In order to avoid this deformation, at least the side of the steel belts which faces away from the rollers is subjected to treatment by shot blasting before being installed in the double belt press.

  • Twin-belt press for manufacturing particle boards
    Patent number: 5112209
    Abstract: In a double-band or similar press the pressure on the mat that is being fed in is increased so rapidly as soon as this mat comes into contact with the heat-transfer surfaces that the outer areas of the mat harden under the great pressure, whereas the heat has still not penetrated into the interior of the mat. This results in an enhancement of the surface quality of the panel. As an example, to this end, a roller gap can be provided before the feed gap.

  • Method of and plant for the manufacture of wood chipboards and similar board materials
    Patent number: 5085812
    Abstract: In a double-belt press for the manufacture of wood chip boards and the like having a width less than the nominal working width of the double-belt press, the forming belts are held in contact with the support structure so as to ensure heat transfer in the edge portion of the pressing zone extending beyond the edge of the filling which produces the boards to the region near the edge of the pressing zone. In this edge portion, an edge filling composed of unbonded particles is compressed on a compressible rotating belt.
