MÜHLEN G400A — Automatic Electric Guillotine for A4 Professional Cutting
Who Is It For?
The MÜHLEN G400A is an electric guillotine for print shops, copy and digital print centres, binding workshops and offices that process paper in volume. It clamps each stack automatically before a servo motor drives the blade, removing the effort and inconsistency of lever-operated cutters. Its compact desktop body brings regular stack cutting together in one machine, and it handles cardboard, fabric and film as well as paper.
Key Features and What They Do
- 400 sheets or 40 mm per cut: Thick stacks are finished in a single pass instead of being split into several cuts.
- Automatic clamping: A document clamping pad presses the stack before the blade comes down, so pages stay put and edges stay clean.
- Laser cutting line: A red laser shows the cutting line in advance, helping you set the size correctly before cutting.
- 300 mm cutting length: Cuts A4 documents from different directions and A3 documents along the short edge, on a table with a millimetre scale.
- Layered safety: Two-button operation, front and rear protective guards and a key-operated automatic blade guard.
- Removable waste tray: Offcuts can be emptied quickly to keep the work area tidy.

Usage and Care Tips
Align the stack on the scaled table against the cutting guide and check it against the laser line; once automatic clamping is complete, press both buttons to start the cut. Empty the removable waste tray regularly so offcuts do not build up. To protect the special steel blade, cut only the materials listed for the machine and keep it in a dry, dust-free place. With a net weight of 19.1 kg, it should stand on a stable worktable.
