摘要：
A method of making a mechanical fastener. The method includes providing a slit web having mechanical fastening elements and spreading the slit web in the cross-machine direction by directing the slit web over at least a first roller having first multiple protrusions around its peripheral surface. The slit web includes a plurality of interrupted slits that are interrupted by intact bridging regions of the web that divide the interrupted slits into a series of spaced slit portions aligned in the machine direction. The first multiple protrusions are positioned such that adjacent protrusions push through consecutive slit portions of a first of the interrupted slits to form a spread mechanical fastening web. An apparatus including the first roller and at least a subsequent roller is also disclosed.
