Abstract

L'invention concerne une cassette qui permet de supprimer le surdimensionnement même si l'on y loge un rouleau de bande de stratification. Une cassette (10) présentant une structure à double couche comprend: un rouleau de bande d'impression (premier rouleau) (26) qui est disposé dans une première couche( L1) et sur lequel une bande d'impression (première bande) (22) à imprimer est enroulée; et un rouleau de bande de stratification (second rouleau) (64) qui est disposé dans une seconde couche (L2) et sur lequel une bande de stratification (seconde bande) (60) à stratifier sur la bande d'impression (première bande) (22) est enroulée. Au moins une partie du rouleau de bande d'impression (26) chevauche au moins une partie du rouleau de bande de stratification (64) dans une première direction parallèle à une première ligne centrale de rotation (C1) qui est le centre de rotation du rouleau de bande d'impression (26). Par conséquent, il est possible de miniaturiser la cassette (10) par comparaison avec un cas où au moins une partie du rouleau de bande d'impression (26) ne chevauche pas au moins une partie du rouleau de bande de stratification (64) dans la première direction.
