The present invention relates to a method for making a substantially cylindrical tool from a substantially planar substrate, wherein the tooling has at least one patterned surface (41). The resulting tooling includes a patterned surface (41) with a sufficiently strong weld (44) that is capable of producing an article having a pattern surface that has a relatively narrow and preferably cosmetically pleasing seam line (42'). Such articles include retroreflective sheeting, structured abrasive articles, adhesive articles suitable for use in personal care products, and the like.
L'invention concerne un procédé relatif à la fabrication d'un outil sensiblement cylindrique à partir d'un substrat sensiblement plat, qui comporte au moins une surface modelée (41). Il en résulte un article à surface modelée (41), avec une soudure suffisamment résistante (44), présentant une ligne de joint (42') relativement étroite et de préférence plaisante du point de vue esthétique. Ce type d'article englobe les revêtements rétroréfléchissants, les articles abrasifs structurés, les articles adhésifs pour produits de soins personnels et autres.
