    摘要： A sheet manufacturing method is provided including the steps of (i) extruding a sheet material to a sheet form; (2) forming a desired sheet by performing a predetermined processing involving dimensional change in a transverse direction of a sheet; (3) measuring a thickness distribution in the transverse direction of the sheet before completion and after completion of the predetermined processing; (4) calculating a manipulated variable corresponding to each measuring position based on a thickness distribution measurement value in the transverse direction of the sheet after completion of the processing; and (5) controlling the thickness of the sheet. In the calculation of the manipulated variable of step (4), a correspondence position in the transverse direction of the sheet after completion of the processing is determined, and a thickness control is performed based on the determined correspondence position in the transverse direction of the sheet.

    摘要： Methods and systems are disclosed for determining plastic components of a blended plastic material. According to a method of the present invention, a blending computer access supply data describing characteristics of each of a plurality of plastic components. The blending computer receives specification data which identifies at least one desired characteristic of the blended plastic material. The blending computer processes the supply data and the specification data to determine combinations of certain of the plastic components that may produce the blended plastic material having the at least one desired characteristic. The blending computer determines, for each combination, a preferred percentage of each of the plastic components of the combination, and reports the combinations and preferred percentages.
