- the dimensions of the outlet 52 of the resin b of this device are as follows: b 'shown in Fig. 21b is 0.1 mm, w' force is 2.5 mm, thickness s is 0.5 mm, and a The inclination angle 7 shown in the figure was 45 °, and the pitch p 'was 2 bandits.
- the resin a and the resin b were co-extruded at a shaping temperature of 260 to produce a composite resin sheet having a thickness of 3 and a width of 50 cm.
- the obtained composite sheet was a composite sheet having a clear black stripe pattern in a transparent base sheet, and was entirely smooth and no warpage was observed.
- the thickness of the resin strip B was 0.1 mm, the width was 2.5 strokes, and the angle with respect to the composite sheet surface was about 45 °.
- the distance between the resin strips B was 2 rows, and the distances d and d 'between the tip of the resin strip B and the sheet surface were 0.62 mm, respectively (FIG. 15d).
- the plurality of flow paths 31 had an inner diameter of the discharge port of 0.7 mm, and the distance between adjacent discharge ports was three.
- ARm and ALm are each 0.2 mm, ⁇ Rn and ⁇ Ln are each 1 ram, the widths of the portions Rm and Lm are each 2 mm, and the widths of the portions Rn and Ln are each 4 mm.
- Example 2 a composite resin sheet having a thickness of 3 mm and a width of 50 cm was continuously manufactured.
- the obtained composite sheet is a composite sheet having a clear black stripe pattern in a transparent base sheet, and the resin strip B has a thickness of 0.1 to 0.2 band and a width of 2 bands. And had the sequence of resin strip B shown in FIG. 15e. The distance between the resin strips B was 3 mm, and the distances d and d 'between the tip of the resin strip B and the sheet surface were 0.5 nun, respectively (Fig. 15e).
- the composite resin sheet which is excellent in transparency, durability, etc., and has various functions, such as design property, Since it can be produced very efficiently by extrusion molding, its industrial value is great.
