Abstract
A magnetic holding device (10) and a method for the manufacture thereof. The device (10) is used in the field of graphic arts such as foil stamping. The device (10) secures a steel back polymer plate to a heating element, for the purposes of transferring thin metal foil or leaf to paper, card, plastics material or similar media. The device (10) has a space locations a plurality of magnets (13) embedded in a body (14) of the device (10). The magnets (13) are preferably Samarium Cobalt Disk magnets and are held within the body (14) by means of an adhesive such as Loctite 620(®*).
Claims13
A magnetic holding device to secure a steel backed polymer plate to a foil stamping heating element, said device having:
- a body having a body surface to engage the plate;
- a plurality of magnets embedded in the body so as to each have a magnetic surface substantially co-planar with respect to said body surface, the magnets being provided to urge the plate into contact with the body and magnetic surface, said magnets being disshaped and having a diameter of approximately 6 millimetres;
- and
- a layer of nickel covering said body surface and the magnetic surface.
A method to produce the device of said claim 1 to 7 wherein said method including the steps of:
- providing said body with apertures to receive said magnets, said apertures being generally cylindrical and extending through said body;
- placing an adhesive in the apertures;
- placing the magnets in the apertures so as to be secured to the body with the aid of the adhesive so that the magnets have an end surface generally coplanar with said body surface;
- nickel plating the body and magnets so that the layer of nickel covers said body and magnetic surfaces.
A magnetic holding device substantially as hereinbefore described with reference to the accompanying drawing.
