Printer Punch Apparatus

With this apparatus, business documents are printed and punched concurrently. This is realized by modifying selected print hammers to serve as punches and providing a corresponding die plate on a printing machine.

A machine in which print hammers 1 normally are driven against paper form 2, ribbon 3 and type slugs 4 to effect printing, has some hammers 5 altered at one end 6 to punch chadless holes 7. Die plate 8 having holes 9 corresponding to the location of each modified hammer-punch 5 is supported between type slugs 4 and paper form 2. Ribbon 3 is made narrower to cover only the printing positions.

With this arrangement the hammers, including those modified, are actuated by armatures 10 of magnets 11 through the usual printing circuits. Chadless holes are preferably produced but the chads can be entirely punched out, if a removal device is provided.

Concurrent printing and punching of documents, such as customer statements, permits the returned stubs to be machine processed. Furthermore, by locating the punching mechanism at the print line, data storage is not required as is necessary when the punch unit is located beyond the printing location.
