<P>PROBLEM TO BE SOLVED: To provide a laminate production apparatus in which the facility cost of rollers for forming an uneven pattern can be reduced, and rollers for forming the uneven pattern can be replaced easily in a short time. <P>SOLUTION: The laminate production apparatus includes a back-up roller, a nip roller, and a chill roller in this order in the direction in which a substrate passes. A laminate is produced by drooping a melted thermoplastic resin from a T-die via an extruder to form a resin film, and passing the resin film and a substrate between the back-up roller and the nip roller, and between the nip roller and the chill roller. The nip roller has an uneven pattern formed on the outer circumferential surface thereof, and the nip roller has a diameter smaller than that of the chill roller and is disposed detachably. <P>COPYRIGHT: (C)2013,JPO&INPIT |
