A method of making a structured surface is disclosed. The method includes providing a thermoplastic backing with multiple rows of upstanding elements. The upstanding elements include stems with proximal ends attached to the thermoplastic backing and distal caps, and each distal cap has an overhanging portion that extends beyond the stem in a first direction. For at least some of the multiple rows, an implement is passed between two adjacent rows, wherein the implement contacts the overhanging portion of at least some of the distal caps in the two adjacent rows such that at least part of the overhanging portion is turned in a second direction, different from the first direction. A structured surface that can be prepared by the method is also provided along with a fastening laminate that includes a carrier and the structured surface and an absorbent article that includes the fastening laminate. A tool useful for carrying out the method is also provided.
A method of making a structured surface, the method comprising:
A tool for shaping distal caps on upstanding elements on a structured surface, the tool comprising a template structured surface and multiple implements, the template structured surface comprising a template thermoplastic backing with multiple rows of template upstanding elements, wherein the template upstanding elements comprise stems with proximal ends attached to the template thermoplastic backing and distal tips, wherein the multiple implements comprise at least one of needles, wires, or shims, and wherein the multiple implements are positioned between the multiple rows of the template upstanding elements on the template structured surface.
A structured surface comprising:
