Patent ID: 7381357

Claim:
A method for producing a plastic sheet, comprising the steps of: extruding a first plastic extrudant with a first extruder to produce a first layer; extruding a second plastic extrudant with a second extruder, the second plastic extrudant being at least partially transparent and including a first color; extruding a third plastic extrudant with a third extruder, the third plastic extrudant including a second color; collecting the second plastic extrudant and the third plastic extrudant in a collection component, the collection component being configured to produce a first mixture; segmenting the first mixture in a segmentation component, the segmentation component being configured to produce a second mixture having distinct segments of the second plastic extrudant and the third plastic extrudant; mixing the second mixture in a turbulator component, the turbulator component including a housing having a first end, a second end, an interior region and an orientation unit, the orientation unit including a rotatable shaft having at least one projection extending therefrom to engage the second mixture and to rotate the second mixture relative to a selection member having a plurality of outlets, and wherein the first end of the housing is configured to receive the second mixture and the second end of the housing is configured to expel the second mixture through the plurality of outlets to produce a mixture layer comprising a non-linear and segmented pattern; and applying the mixture layer to the first layer to produce an extrudate product, the third plastic extrudant being positioned within the mixture layer at varying depths relative to the partially transparent second plastic extrudant to create a depth characteristic when the extrudant product is viewed from a top surface.
