PROBLEM TO BE SOLVED: To provide a laminate production apparatus in which facility cost of rollers for forming an uneven pattern can be reduced, the rollers for forming an uneven pattern can be replaced easily in a short time.SOLUTION: The laminate production apparatus includes a back-up roller 10, a nip roller 11, and a chill roller 12 in this order in the direction in which a substrate 1 passes. A laminate is produced by drooping a melted thermoplastic resin from a T-die 13 via an extruder to form a resin film 2 and passing the resin film 2 and a substrate 1 between the back-up roller 10 and the nip roller 11 and between the nip roller 11 and the chill roller 12. The back-up roller 10 has an uneven pattern 10a formed on the outer circumferential surface thereof, and the back-up roller 10 has a diameter smaller than that of the chill roller 12 and is disposed detachably. |
