PROBLEM TO BE SOLVED: To simply manufacture different kinds of composite resin sheets without exchanging a nozzle by forming a resin discharge port for a base body resin sheet into a slit shape, and arranging resin discharge ports for a resin stripe on the outer peripheral surface of a cylindrical discharge port at predetermined distances, and rendering the cylinder rotatable. SOLUTION: Resin for forming base body resin sheets is discharged from a slit-like discharge port 19 to a resin confluence part 17 passing through flow paths 12, 15. Resin for forming a resin stripe is passed through a flow part 14 to be discharged from a group of discharge ports 20, 20-1, 20-2 to the resin confluence part 17 via a discharge metal piece 8. In the resin confluence part 17, both resins are joined and then flow out simultaneously from an outlet 18 via a composite resin flow path 16. Herein, the discharge metal piece 8 is made cylindrical, and a group of discharge ports 20, 20-1, 20-2 are provided which comprise a predetermined shape arranged in row at predetermined distances on the outer periphery thereof. Furthermore, the distance metal piece 8 is made rotatable to change a group of the discharge ports 20, 20-1, 20-2. |
