  • Patent number: 6656399
    Abstract: Shaped bodies, such as boards, are manufactured from particles having a surface with a wax layer, such as straw, hemp stalks, maize stalks, grapevine stalks and the like. The particles are first comminuted, then heated and then further comminuted. Thereafter the particles are admixed with a binder to form a mixture, the mixture is scattered into a mat, and the mat is then pressed into the shaped body of the desired size.

  • Patent number: 6322346
    Abstract: The invention relates to a device for the continuous production of plate-shaped products, comprising two endless strips which are positioned one above the other and can be driven. A working gap is formed between the sides of said endless strips, said sides being adjacent to one another and each being conveyed via a support surface. The starting material for processing is conveyed through said working gap which is bordered on each side by an accompanying strip. Said accompanying strip is situated along said working gap between the two endless strips and moves with them, consisting of a flexible sealing strip which has a friction surface on at least one face, said face facing towards an endless strip. Said friction surface increases the static friction between the flexible sealing strip and the endless strip.
