Method of producing safety labels - involves sticking strip of hard magnetic metal and silicon paper onto support film and punching holes before sticking light magnetic strip and laminating before final label stamping

摘要

A hard magnetic metal strip (5) is glued to the support film (1) and a layer (6) of silicon paper is laid on top of the strip. The film, with strips, is then passed through a hole punch (7) which makes evenly spaced holes in the metal strip. The silicon strip is then removed from the hard metal strip onto which a soft magnetic porous metal band (9) is stuck. The final strip (10) is then laminated with film (12,13) and individual labels (14) are then stamped out (11). ADVANTAGE - The strip of hard magnetic material is cut exactly on the support film so there is little chance of over or under cutting.
