摘要
A system for manufacturing pluralities of consecutive sheets bearing successively varying arrangements of design features is disclosed. The system may include a pattern imparting roller having a substantially cylindrical acting surface reflecting features of a design pattern thereon, the design pattern having a machine direction repeat length; and a separating mechanism disposed downstream of the pattern imparting roller, configured to effect repeated and spaced cutting, perforating or scoring along separation lines, between portions of a material web, the separation lines being spaced apart on the web by sheet length measured along the machine direction. The sheet length is less than the design pattern repeat length.
