Abstract
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. The resulting tooling includes a patterned surface with a sufficiently strong weld that is capable of producing an article having a pattern surface that has a relatively narrow and preferably cosmetically pleasing seam line. Such articles include retroreflective sheeting, structured abrasive articles, adhesive articles suitable for use in personal care products, and the like.
