US 2003/0165652 A1 · Method and device for making a magnetically mountable substrate construction from a selected substrate

Abstract

The present application relates to a method and device for making a magnetically mountable substrate construction from a selected substrate for magnetic mounting to a structure including magnetizable material. The magnetically mountable substrate may be formed from a pressure sensitive adhesive magnetic sheet material which includes a flexible magnetic substrate having a first major surface and a second major surface, with a pressure sensitive adhesive layer adhering to the first major surface and a release layer, such as silicone release layer, adhering to the second major surface. The magnetic sheet may be provided in the form of continuous lengths wound in a roll with the release layer in contact with the pressure sensitive layer of an adjacent winding to facilitate unwinding without delamination.

A device for making a magnetically mountable substrate construction from a selected substrate for magnetic mounting to a structure including magnetizable material, the substrate construction comprising the selected substrate, a carrier portion formed from a flexible magnet substrate including permanently magnetized material, and pressure sensitive adhesive bonding the selected substrate to the carrier portion, said device comprising:

a flexible magnet substrate having an adhesive carrying surface and a release surface opposite said carrying surface, said flexible magnet substrate including permanently magnetized material which enables said flexible magnet substrate to be magnetically mounted to structures including magnetizable material;
a layer of pressure-sensitive adhesive provided on said adhesive carrying surface of said flexible magnet substrate;
said flexible magnet substrate being wound into a roll such that said layer of pressure-sensitive adhesive directly engages the release surface of said flexible magnet substrate;
said adhesive carrying surface having a greater affinity for adhesive bonding than said release surface so as to enable said device to be used to make the magnetically mountable substrate construction comprising the selected substrate, a carrier portion of said flexible magnet substrate, and a portion of said adhesive layer adhesively bonding said selected substrate to said portion of said flexible magnet substrate by (a) unwinding a lead end portion of said flexible magnet substrate with said adhesive remaining bonded to the adhesive carrying surface of the unwound lead end portion, and (b) engaging the selected substrate with the adhesive on said unwound lead end portion and applying pressure to adhesively bond the selected substrate to said unwound lead end portion, and (c) cutting the unwound lead end portion so as to form said carrier portion.
