    Patent number: 6251330
    Abstract: Method and device for manufacturing plastic-based materials in web form, such as floor and wall covering materials, and also such a material manufactured by the method. During the production, spherical particles (12) in substantially one size are used. The particles are deposited as a layer (18) on a substrate (1) by doctoring by means of allowing the particle mass to flow down into a gap between a depositing member (16) and the passing substrate (1). Thereafter, the particles are sintered together by heating, whereafter the solidified layer (25) is caused to fuse into a homogenous form by means of heating during simultaneous compression in order to shape the web material (26).
