    摘要： A method and apparatus for forming a mechanical fastener. A preferred embodiment of the method includes moving a substrate along a web path, where the substrate includes a first major surface and a plurality of stems extending from the first major surface of the substrate and each of the stems includes a stem end, radiantly heating the stem ends to form softened ends, and thereafter deforming the softened ends into convex heads with a deformable surface. A preferred embodiment of the apparatus includes a web conveyor, where the web conveyor defines a web path, a heating source located adjacent the web conveyor and a deformable surface located down the web path from the heating source, where the deformable surface includes a durometer hardness of greater than 10 Shore OO and less than 70 Shore A.

    摘要： A friction control article including a backing layer having a first surface with an array of at least 100 upstanding stems per square inch and a second surface. At least a portion of the upstanding stems is an elastomeric material and the stems have an aspect ratio of at least 1.25. The first surface has a static coefficient of friction when dry of at least 0.6 and a static coefficient of friction when wet within 20% of the static coefficient of friction when dry. The first surface has a peel strength and a tensile strength of substantially zero when engaged with another slip control article. The first surface has a relatively high shear strength when engaged with another slip control article. The high shear forces are due primarily to the frictional properties of the elastomeric materials, not a mechanical interlock of the stems, such as on a mechanical fastener.

    摘要： Method for making a stem web material having a plurality of stems extending from discrete regions (patches or stripes) of the web, comprising: a) providing a web (e.g. nonwoven, woven or knit textile fabric; paper; microporous membrane, polymer film; etc.); b) providing discrete quantities of a polymer at a temperature above its softening point or in molten state; c) fusing the discrete quantities of polymer to the web; and d) forming a plurality of stems in each of the discrete quantities of polymer material. The stems can be formed by pressing the web on which the patches or stripes of polymer are deposited against a tool having a surface with a plurality of stem-forming holes. The stems can be given enlarged ends by bringing the surface of the stem web close to a heated surface.
