Systems, methods, and apparatus are disclosed for making patterning tools from one or more discrete elements. Such tools can have one or more "seams" or joints where the individual elements abut which can limit the tools' performance and utility in roll-to-roll manufacturing. Methods are described herein for producing "near-seamless" tools, that is, tools having seams that exhibit minimum disruption of the tool pattern and thus improved material produced by such tools. The patterning tools can be cylindrical and/or closed in shape.
L'invention concerne des systèmes, des procédés et un appareil de production d'outils de formation de motifs à partir d'un ou de plusieurs éléments discrets. Ces outils comprennent une ou plusieurs coutures ou joints dont les éléments individuels viennent en about, ce qui peut limiter les performances et les fonctions des outils dans une fabrication rouleau sur rouleau. Les procédés précités permettent de fabriquer des outils pratiquement sans couture, c'est-à-dire, des outils qui présentent des coutures interrompant le motif de l'outil de manière minimum, et donc d'améliorer les matériaux produits par ces outils. Les outils de formation de motif peuvent être cylindriques et/ou de forme fermée.
