Method of producing plastic sheets with integrated geometric decorative patterns

摘要: A method and apparatus for producing synthetic resin sheets having geometric decorative patterns extending through the thickness of sheet as a substantially identical pattern image corresponding to portions exposed surfaces thereof, wherein differently colored particles are selectively introduced into individual spaces which confined by enclosing members on support provide regular particle masses over surface in pattern, then converted pre-formed support, color still being retained, resulting assembly heated at temperature sufficient cause fusion or sintering together comprising sheet, original exist repeating areas extend sheet.
