  • Patent number: 7371430
    Abstract: The invention relates to a method for structuring endless belts (1), particularly steel belts, for presses, e.g. double belt presses. According to the invention, a coating is applied to an outer surface of the belt after which metal is removed from and/or applied to the belt. The coating is formed by individual drops, which are projected against the outer surface of the belt and remain thereupon and/or, as done in the prior art, a surface-covering coating is applied, which is degraded and/or removed, e.g. oxidized, in a preferably point-by-point manner by the action of thermally active beams, particularly laser beams, whereupon metal is removed from and/or applied to the uncoated area.

  • Patent number: 7144481
    Abstract: Endless steel band for belt presses, especially double belt presses, with a thickness between 2 mm to 4 mm, preferably 2.5 mm to 3.5 mm, which is turned around on drums of the belt press, and whose surface has a maximum medium roughness up to RZ 50.5 ?m, in which a plurality of depressions are provided starting from the surface of the steel strip and extending into the steel strip, the depressions being substantially evenly distributed and reaching from the surface of the steel strip 200 ?m to 600 ?m deep into the steel band. Such steel band can be used for the production of plates, preferably wood-based plates, especially chipboards, with elevations.
