Abstract
The present invention relates to a sheet adhesive by pressure application including a substrate covered with an adhesive on a front surface, and non-adherent elements protruding with respect to the front surface and likely to yield by application of a pressure. The substrate includes a meshing of channels opening at least at one edge of the sheet, and the non-adherent elements are bands forming roofs above the channels.
Claims18
An adhesive sheet that adheres by an application of a pressure, the adhesive sheet having a plurality of edges and comprising:
- a substrate having a first thickness, the substrate including:
- a front surface at least partially covered with an adhesive;
- and
- a meshing of channels opening at least at one edge of the plurality of edges;
- and
- a plurality of non-adherent elements having a second thickness smaller than the first thickness of the substrate, the plurality of non-adherent elements connected to and protruding from the front surface of the substrate.

A pressure sensitive adhesive sheet having at least one edge, comprising:
- a substrate having a front surface and including a meshing of channels opening at least at the at least one edge;
- an adhesive at least partially covering the front surface;
- and
- a plurality of non-adherent roofs covering the meshing of channels and protruding from the front surface, a first thickness of the substrate being larger than a second thickness of the plurality of non-adherent roofs, the plurality of non-adherent roofs being constructed and arranged so as to collapse into the meshing of channels when a pressure is applied to the plurality of non-adherent roofs.
