Use of a three-dimensional system having a flexible structure

Abstract

Disclosed is use of a three-dimensional system of thick knitted fabric type, having a flexible structure to produce a device capable of limiting and partly eliminating the energy and calories due to reheating, and to produce a device designed for preparation, polishing or shining and also to produce a surface that has to undergo or may undergo a treatment involving heating and devices capable of limiting and partly eliminating the energy and calories due to heating. The device may in particular be made up of the following layers: layer 1: an outer surface of uniformly laid needle-punched fibres of filaments, or felt, or of abrasive cloth type; layer 2: optionally a base to which the fibres, or abrasive grains, are fixed, to give the system rigidity; layer 3: a layer of adhesive; layer 4: optionally a jersey knit for clinging to a Velcro-type surface; layer 5: optionally a Velcro-type surface; layer 6: optionally a layer of adhesive to fix the Velcro-type surface to the three-dimensional system; layer 7: a three-dimensional system of thick knitted fabric type, having a flexible structure; layer 8: a layer of adhesive; and layer 9: a rear backing.

Description

technical field [0001] The invention relates to the use of a three-dimensional system of the thick knit type with a flexible structure for the production of wearing, polishing or buffing devices. In particular, the present invention relates to the application of a three-dimensional system of the thick knit type with a flexible structure for the production of abrasive, polishing or buffing discs for the purpose of retouching and finishing surfaces which have been painted or otherwise Finishing and / or treatment. The invention also relates to a device capable of buffing, polishing and / or wearing. Background technique [0002] French patent application FR2806424 discloses a thick double jersey fabric with a flexible structure, which has flexible and elastic properties and a minimum thickness of 3 mm. This thick knit fiber has stable properties, resistance to sagging and ability to recover its original thickness, especially for vehicle seat covers. [0003] French patent appli...

AI Technical Summary

Problems solved by technology

Therefore, abrasion, grinding and / or polishing operations by mechanical means are often necessary, which can lead to heating of the disc and support, which leads to faster degradation of the disc and also of the support (especially holograms and / or supports). or halo formation)
