Abstract

A method of modifying a male fastener of a fastening system includes feeding a web having a base substrate and a male fastening material to a modifying member having an outer surface. The male fastening material has a plurality of male fasteners with a first, unmodified profile. The profile of at least some of the plurality of male fasteners of the male fastening material are modified by engagement of the plurality of male fastener with the outer surface of the modifying member and by causing the plurality of male fasteners to slip along the outer surface of the modifying member. A modified male fastening material includes a plurality of male fasteners modified from a first profile to a second, different profile by passing the male fastening material over the outer surface of the modifying member.

First claim

What is claimed is:

1. A method of modifying a male fastener of a fastening system, the method comprising:
feeding a web comprising a base substrate and a male fastening material to a modifying member having an outer surface with a plurality of holes, the male fastening material comprising a plurality of male fasteners having a first, unmodified profile;
applying a force to the web to facilitate contact between at least some of the plurality of male fasteners and the outer surface with the plurality of holes of the modifying member; and
modifying the profile of at least some of the plurality of male fasteners of the male fastening material by causing the plurality of male fasteners to slip along the outer surface with the plurality of holes of the modifying member.

2. The method of claim 1 , wherein modifying the profile of at least some of the plurality of male fasteners of the male fastening material comprises causing the plurality of male fasteners to have greater widest dimension.

3. The method of claim 1 , wherein modifying the profile of at least some of the plurality of male fasteners of the male fastening material comprises making a height of the plurality of male fasteners shorter.

4. The method of claim 1 , wherein modifying the profile of at least some of the plurality of male fasteners of the male fastening material comprises making a length of the plurality of male fasteners greater.

5. The method of claim 1 , wherein the plurality of male fasteners are adapted to engage a loop fastener.

6. The method of claim 4 , wherein the plurality of male fasteners comprises at least one of hooks, bulbs, mushrooms, arrowheads, balls on stems, stems.

7. A method of modifying a male fastener of a fastening system, the method comprising:
feeding a web comprising a base substrate and a male fastening material to a modifying member having an outer surface, the male fastening material comprising a plurality of male fasteners having a first, unmodified profile;
applying a force to the web to facilitate contact between at least some of the plurality of male fasteners and the outer surface of the modifying member;
modifying the profile of at least some of the plurality of male fasteners of the male fastening material by causing the plurality of male fasteners to slip along the outer surface of the modifying member; and
cutting a discrete segment from the web slipping on the outer surface of the modifying member using a knife roll.

8. The method of claim 7 , wherein the modifying member is an anvil roll.

9. The method of claim 8 , further comprising transporting the discrete segment via a vacuum pressure applied to the outer surface of the anvil roll by a vacuum source.

10. The method of claim 9 , further comprising transferring the discrete segment to a product web.

11. A method of modifying a male fastener of a fastening system, the method comprising:
feeding a web comprising a base substrate and a male fastening material to a modifying member having an outer surface, the male fastening material comprising a plurality of male fasteners having a first, unmodified profile; and
modifying the profile of at least some of the plurality of male fasteners of the male fastening material by pneumatically engaging the plurality of male fasteners with the outer surface of the modifying member and causing the plurality of male fasteners to slip along the outer surface of the modifying member.

12. The method of claim 11 , wherein modifying the profile of at least some of the plurality of male fasteners of the male fastening material by pneumatically engaging the plurality of male fastener with the outer surface of the modifying member comprises using a vacuum to draw at least some of the plurality of male fasteners against the outer surface of the modifying member.

13. The method of claim 11 , wherein the modifying member is free from a heat source.
