This invention is directed to a sanitary product attachment means comprising a connection member () having a flexible base carrier (), whereas on one main surface of the connection member () an underwear connection means () is present which is configured to fix the connection member () to a piece of underwear () and on the opposing main surface of the connection member () an absorbent member connection means () is present which is configured to fix the connection member () to the underside of an absorbent member ().

Sanitary product system

The invention relates to a method for forming a fastener having fastener members () wherein molten polymer material is deposited by a deposition device onto a contact release surface (), thereby forming preform projections (), which contact the front surface () of a carrier () with their terminal ends () and bond to the carrier (). The carrier () is removed with the preform projections () attached, thereby separating the preform projections () from the contact release surface () and forming fastening members () projecting from the front surface () of the carrier (). The invention relates further to a method for manufacturing a precursor web () for manufacturing a fastener, a fastener web () for engaging with a loop fabric and a precursor web () for manufacturing a fastener.

Method for manufacturing fasteners and precursor webs, a fastener and a precursor web

A method of making a structured surface and a mechanical fastener precursor are disclosed. The method includes providing a thermoplastic backing with spaced-apart, upstanding posts with base portions attached to the thermoplastic backing and distal tips; deforming the distal tips to form caps on at least some of the spaced-apart, upstanding posts to provide capped posts, wherein at least some caps upon forming touch at least one adjacent cap; and separating the capped posts. Typically, the at least some caps upon forming are shaped at least partially by the at least one adjacent cap. The mechanical fastener precursor includes a thermoplastic backing and upstanding male fastening elements with bases attached to the thermoplastic backing and distal caps larger in area than the cross-sectional area of the bases, wherein the bases of the male fastening elements are spaced apart, wherein at least some of the distal caps touch at least one adjacent distal cap.
