  • Publication number: 20150072111
    Abstract: Method for manufacturing a floor covering in which first the material of the layer is provided, said material being transferred to a sheet-shaped mould forming the layer and then fed to a device for vulcanisation, wherein the device comprises a roller arrangement with rollers, wherein a separating layer is provided between roller and layer, and wherein the separating layer is provided with a transmission structure, said transmission structure being transferred to the layer while the layer is running through the device, as a result of which the structure with zones of a different gloss level is formed on the layer, said invention further relating to a floor covering manufactured in this way.

  • Patent number: 6503424
    Abstract: A multicolored, patterned floor covering is disclosed along with a method for its manufacture. The floor covering is made of a sheeting which has a first color, and a granular material dyed differently from the sheeting which is embedded in the sheeting along at least in the area of the top side. The sheeting and the granular material consist of cross-linkable, elastomeric materials, the granular material comprising particles which have at least two subregions dyed differently from each other and from the sheeting. The quantity and color of the fractions of each component as selected so that the mixed color resulting from an homogeneous intermixing of all the components contained in the floor covering agrees with the first color.

  • Patent number: 5154868
    Abstract: A method of manufacturing a randomly patterned floor covering having contrastingly-colored zones from a preform of rubber in which the preform is cut in pieces, each of which are molded into a blank having projections extending from a top side of the blank in relief-like fashion, solidified by vulcanization and then machined by cutting only in the region of the projections. The rubber forming the contrastingly-colored zones is mixed with contrastingly-colored particles in an amount of at least ten percent by weight. These particles are substantially free of flat surfaces and are in, at least, an advanced state of vulcanization. The particles located in the projections extending from the top side of the blank are exposed during the cutting step.
