PURPOSE:To obtain a molded product having a small stucco like embossed patterns, by co-extruding resins from two extruders at different speeds to prepare a sheet such that one resin parts are partially formed to one surface of the other resin layer and generating sink marks to the opposite side surface of said resin layer. CONSTITUTION:Resins are co-extruded at different speeds from two extruders 1, 2 to prepare a sheet like article wherein lower layer resin parts 5 are partially formed to the under surface of an upper resin layer 4. Subsequently, said sheet like article is cooled to generates sink marks 7 to obtain the desired molded product 6 having an embossed pattern 8. |
