摘要： There is disclosed a method for extruding synthetic plastic sheet material having differentially colored bands which utilizes an extrusion die block having a chamber in which is disposed a pair of sleeve members. The matrix resin is supplied to the die block chamber on the opposite side of the die chamber from the extrusion orifice and the differentially colored resin is supplied to the sleeve members. Each of the sleeve members has a pair of bores therein, one of which receives the differentially colored resin and communicates with the other which in turn has discharge openings in the surface thereof adjacent the extrusion orifice. The sleeve members are spaced apart so as to provide a channel therebetween and are spaced from the walls of the die chamber so as to provide channels thereabout whereby matrix resin will flow both between and about the sleeve members while resin is discharged intermittently through the sleeve members. The matrix resin flows towards the discharge openings from the sleeve members and encapsulates the differentially colored resin issuing therefrom. The intermittent discharge means may be operated in different directions so as to provide a basketweave design, bands of color at right angles to each other and the like. Three extruders may be utilized to provide two color bands with different colors being supplied to each of the sleeve members.
