A method of making a mechanical fastener. The method includes providing a slit web having mechanical fastening elements, applying tension to the slit web in the machine direction, and spreading the slit web in the cross-machine direction by directing its side edges over two rotating diverging disks to provide a spread mechanical fastening web. The slit web includes a plurality of interrupted slits that are interrupted by intact bridging regions of the web. The two rotating diverging disks are laterally spaced and have a support surface between them that contacts the slit web during the spreading. The spread mechanical fastening web includes multiple strands of the slit web attached to each other at least at some of the intact bridging regions and separated from each other between at least some of the intact bridging regions.

1. A method of making a mechanical fastener, the method comprising: providing a slit web having mechanical fastening elements and a length in a machine direction, wherein the slit web comprises a plurality of laterally separated interrupted slits that are interrupted by intact bridging regions of the web, wherein the interrupted slits extend in a first direction not parallel to a cross-machine direction, and wherein for at least some adjacent interrupted slits, the intact bridging regions are staggered in a direction transverse to the first direction;applying tension to the slit web in the machine direction; andspreading the slit web in the cross-machine direction by directing its side edges over two rotating diverging disks to provide a spread mechanical fastening web, wherein the two rotating diverging disks are laterally spaced and have a support surface between them that contacts the slit web during the spreading, and wherein the spread mechanical fastening web comprises multiple strands of the slit web attached to each other at least at some of the intact bridging regions and separated from each other between at least some of the intact bridging regions. 2. The method of claim 1, wherein the support surface is connected to the two rotating diverging disks. 3. The method of claim 1, wherein the support surface is flush with the two rotating diverging disks' peripheral surfaces. 4. The method of claim 1, wherein the support surface bulges outward beyond the two rotating diverging disks' peripheral surfaces. 5. The method of claim 1, wherein the side edges of the slit web are held to the diverging disks' peripheral surfaces using at least one of continuous belts, pins, vacuum, or forced air jets. 6. The method of claim 1, further comprising heating the spread mechanical fastening web. 7. The method of claim 1, wherein slit web is arranged so that the mechanical fastening elements face away from the support surface. 8. The method of claim 7, wherein the support surface is heated. 9. The method of claim 1, wherein the slit web is arranged so that the mechanical fastening elements face toward the support surface. 10. The method of claim 9, wherein the slit web is coated with adhesive on its surface opposite the mechanical fastening elements. 11. The method of claim 1, further comprising directing the spread mechanical fastening web onto a high-friction roller. 12. The method of claim 1, wherein the multiple strands of the slit web attached to each other at least at some of the intact bridging regions form an angle of less than 90 degrees. 13. The method of claim 1, further comprising spreading the spread mechanical fastening web in a cross-machine direction a second time by directing its side edges over a second set of two rotating diverging disks, wherein in the second set, the two rotating diverging disks are laterally spaced and have a support surface between them that contacts the spread mechanical fastening web during the spreading a second time. 14. The method of claim 1, further comprising laminating the spread mechanical fastening web to a carrier. 15. The method of claim 14, wherein the carrier is provided with a layer of adhesive, wherein the spread mechanical fastening web is bonded to the carrier with the adhesive to form a laminate, and wherein the adhesive is exposed between the multiple strands in the laminate. 16. The method of claim 14, wherein the carrier is a nonwoven web. 17. The method of claim 6, wherein heating the spread mechanical fastening web comprises using non-contact heating. 18. The method of claim 1, wherein the first direction is the machine direction. 19. The method of claim 1, wherein the mechanical fastening elements are male fastening elements comprising upstanding posts having bases attached to the slit web. 20. The method of claim 1, wherein the slit web has loops.
