ABSTRACT:
A device is provided for catching and holding loose metal articles accidentally dropped into a printing machine, thus preventing the articles from being fed into the press and damaging printing cylinders therein. The device is a magnet in the shape of elongate bar adjustably positioned over the input opening of the printing press and positioned downstream of the automatic feeding apparatus for the press. The magnetic bar is spaced a distance above the path of sheet stock being fed into the printing press so that metal articles accidentally dropped onto or carried by the sheet are magnetically picked up and held until removed by maintenance personnel or a press operator.
