ABSTRACT:
A magnetic clipping device especially suitable for magnetically retaining on ferromagnetic walls sheet-like articles which may also be stitched or bound together, consists of two permanent magnet face-like elements between which the article is retained which are coupled with each other by a joint or hinge. The permanent magnet elements each consist of a relatively thin permanent magnet foil having a thickness up to 1mm which consists of a rubber- or plastic resin-based anisotropic powder like permanent magnet material. The foils are thoroughly magnetized to define relatively wide stripe-like magnet poles for generating magnetic adhering faces, and the permanent magnet foils are so disposed that opposite stripe-like pole faces face opposite one another.
