Abstract: A method and equipment for making plastic floor tiles of different thickness includes polyvinyl chloride (PVC) of one color or different colors heated first and then moved to a first press roller unit of a compress extending machine to be compressed into a first half-finished product. Then this first half-finished product get through a second and a third press roller units to be respectively compressed into a second half-finished product and a third half-finished (or finished) product. Further, a heating device is provided respectively beside the second and the third press roller units for heating the half-finished products with balanced temperature. Thus, the half-finished product is properly fused to make finished plastic floor tiles with different thickness from 0.5 mm to 3 mm.

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.

Abstract: The invention concerns a homogenous, in particular multicolored plastic sheet or panel, based on ethylene vinyl acetate copolymer (EVA) as binder with a filler content of 30 to 80 wt. % and a process for producing it. In other embodiments the binder contains, in addition to the 70 to 85 wt. % of EVA, polypropylenes to improve the processability (tendency to adhere), EPDM to improve the flexibility, and polyethylenes to reduce the tendency to soiling. In the process described, several additives, each consisting of a binder containing at least some ethylene vinyl acetate copolymer, up to 80 wt. % of fillers and up to 5 wt. % of pigments, are mixed, plasticized and granulated or comminuted to form granules or chips of assorted colours which are mixed and, possibly after other processing operations, pressed to form the plastic web or plates.

Abstract: A novel process for fabricating a multi-colored foamed speckled thermoplastic sheet is disclosed, wherein differently colored preformed thermoplastic sheets are separately comminuted into particles by grinding the sheets at the temperature about equal to the glass-transition temperatures of the sheets. The ground fine particles of different colors are mixed in an appropriate ratio and are then calendered to form sheets. This process is economical and convenient for mass production.
