4. Working Principle of an 820 Automatic Platen Die Cutting Machine

An SQ 820 automatic die cutting machine is built on a classic platen press principle with integrated

automation modules. The basic working process is:

1. Sheet Feeding: Sheets are stacked on a feeder table. The automatic feeder separates individual sheets

   using air blast and vacuum suckers, then transfers them onto the feed board.

2. Registration: Mechanical or servo‑driven side lays and front lays align the sheet to a fixed reference

   position to ensure accurate cutting within tight tolerances.

3. Die Cutting / Creasing: The platen closes against the die chase where a steel rule die is mounted.

   High pressure is applied to cut, crease, emboss or perforate the sheet according to the die layout.

4. Stripping (Optional): A stripping station equipped with dedicated tools removes waste sections from

   the sheet, leaving finished blanks.

5. Delivery: Processed sheets or blanks are carried to the delivery section and stacked into a neat pile

   ready for further operations such as folding and gluing.

Modern SQ 820 automatic die cutting machines include PLC control, sensors and safety interlocks to synchronize all modules

and guarantee safe, stable production.
