PURPOSE:To freely change the form of colored band during manufacturing thermoplastic resin sheet having transparent resin layer made of transparent thermoplastic resin and the colored band embedded in the transparent resin layer. CONSTITUTION:A conduit 2, through which colored thermoplastic resin (b) is supplied, is arranged in the manifold 3, into which transparent thermoplastic resin (a) is supplied, of a mold 1. The conduit 2 is supported rotatably about its axis center to the mold 1. By rotating the conduit 2 about its axis center, the position of the slit 8 formed on the conduit 2 in the manifold 3 is changed. |
