METHOD FOR SELECTIVELY APPLYING TEXTURES ON A SUBSTRATE VIA WORK ROLLER PRESSURE-DEPENDENT, LOCALIZED PLASTIC DEFORMATION

A substrate (106) (e.g., metal or non-metal sheet) can have multiple textures on a surface of the substrate. The various textures can be impressed or applied on the surface of the substrate (106) by passing the substrate (106) between multiple pairs of work rolls (104A, 104B) that each include at le...

Summary:A substrate (106) (e.g., metal or non-metal sheet) can have multiple textures on a surface of the substrate. The various textures can be impressed or applied on the surface of the substrate (106) by passing the substrate (106) between multiple pairs of work rolls (104A, 104B) that each include at least one textured work roll (104A, 104B) for transferring a texture of the work roll (104A, 104B) onto the surface of the substrate (106). The pairs of work rolls (104A, 104B) apply the various textures on the surface of the substrate (106) while maintaining a thickness of the substrate (e.g., with substantially no reduction in a thickness of the substrate). A single pass of the substrate (106) between the pairs of work rolls (104A, 104B) can allow various different textures, patterns, or features to be applied to the surface of the substrate (106) while the thickness of the substrate remains substantially constant. Un substrat (106) (par exemple une feuille métallique ou non) peut présenter de multiples textures sur une surface du substrat. Les diverses textures peuvent être imprimées ou appliquées sur la surface du substrat (106) en faisant passer ce dernier entre de multiples paires de rouleaux de travail (104A, 104B) qui comprennent chacune au moins un rouleau de travail texturé (104A, 104B) conçu pour transférer une texture du rouleau de travail (104A, 104B) sur la surface du substrat (106). Les paires de rouleaux de travail (104A, 104B) appliquent les diverses textures sur la surface du substrat (106) tout en conservant une épaisseur du substrat (par exemple quasiment sans réduction d'une épaisseur du substrat). Un seul passage du substrat (106) entre les paires de rouleaux de travail (104A, 104B) peut permettre d'appliquer divers motifs, textures ou caractéristiques sur la surface du substrat (106) alors que l'épaisseur du substrat reste sensiblement constante.
