Automatic Carbon Paper Insertion

Carbon paper is often packaged in folders containing a predetermined number of carbon paper sheets. This packaging can be accomplished automatically with a mechanically moved electromagnet operating upon a ferromagnetic sheet separating groups of the predetermined number of carbon paper sheets.

The carbon paper sheets are cut from a bulk roll into individual sheets by a rotary sheeter. Separator sheets, which have been sprayed or painted with an iron oxide, are inserted manually between each group of twenty-five produced by the rotary sheeter. A relatively thick separator board is inserted at occasional intervals to permit easy handling, and a relatively large stack of sheets is assembled.

Mechanical linkages move an electromagnet between the stack and a moving endless belt carrying folders opened to each receive one group of twenty-five sheets. Magnetic power of the electromagnet is limited so that only one group of twenty-five and no group containing a separator board can be picked up by the magnet. Magnetic power is released when each group of sheets is about 1/4 inch from the folders.

The entire process proceeds automatically. The folders are held open with air suction and released after a stack has been dropped into a folder. Failure to pick up a stack indicates the presence of a separator board on the top of the stacked sheets. Linkages then position a suction plunger which removes the board.
