Sterling® Digipunch


  • DP1
  • DP Drum Bypass

The Sterling® Digipunch® is an economical high speed automatic paper punching machine designed for short run binderies as well as digital and commercial printers. The machine allows for punching up to 72,000 sheets per hour! That's a big pile of paper for a small machine and a half million sheets per shift.

The Sterling® Digipunch® features a variable pile lift, which allows for slowing the machine down for difficult jobs, such as stock that is curled, stock with static, or acetate. Punch sheets with covers or tabs intermixed.

A touch screen offers complete automatic set up and automatic changeovers. The touch screen takes the guesswork out of the maintenance cycle by prompting operators when it is time to lubricate or sharpen the die. Unlike many other machines, it is possible to run the machine in reverse to clear jam ups.

Punch sheets from 4.25 X 5.5 inches to 12 X 14 inches for Plastic Coil, Double Loop Wire, Plastic Comb, Three Hole-- or any hole pattern. The optional Drum Bypass is a belt changeover system for heavy board. This will enable the sheet to be delivered without having to bend by traveling around the drum.

The Sterling Digipunch offers the latest development in paper punching equipment to make swift set up and changeovers. Embrace the latest in digital technology with The STERLING DIGIPUNCH.

It will also punch double row wrap around covers, windows, doorhangers, and tags. The machine can punch any shape hole, anywhere on the sheet.

Punch at 130 strokes per minute or 125,000 sheets per hour on the Sterling Punchmaster. The machine employs four way registration to ensure dead on accuracy. The Punchmaster can be pre-loaded while running so that the operator is free to off-load the sheets and deliver them to the binder. The shingling of the sheets on the vari-speed conveyor maximizes efficiency and facilitates quality control. An air feeder is available enabling the punching of: Heavy board, signatures, or special stock. A jogger may be added to the system by simply lifting up the delivery tray and placing the jogger at the end of the conveyor. Since the Punchmaster is built in The United States, parts are readily available from a variety of local sources.

The Punchmaster will punch signatures or single sheets from 4 x 5 inch cards all the way up to 20 x 20 inch calendars. Punch a variety of stock such as: Paper, board, plastic, vinyl, or leather as well as aluminum sheets!

This machine can handle a greater variety of jobs than any other punch and can produce many products that are die cut more quickly and cleanly without the need for stripping. It can also punch many jobs that would otherwise have to be punched manually. If you cannot punch it on the Punchmaster, it cannot be punched automatically. Punch it all with the Punchmaster.
