Mühlen H20A — Electric Coil Binding Machine with Motorised Coil Insertion
Who Is It For?
The Mühlen H20A electric coil binding machine works with 4:1 coil binding material and is aimed at offices, copy and print centres, schools and corporate archives that bind regularly. It handles documents from 1 to 500 sheets, so a short proposal and a thick manual can be finished on the same machine. With a punching and binding width of up to 30 cm, it also suits users who work with A4 and longer formats.
Key Features and What They Do
- Motorised coil insertion: an electric motor drives a roller that spins the coil through the punched holes in seconds, removing the need to twist coils in by hand.
- Double-hinge press handle: the single-arm, double-hinge handle and special steel blades punch up to 20 sheets at once with much less resistance and pressure.
- Free-pin punching: pins can be engaged or disengaged so holes are punched in the number and width each document needs.
- 3-level margin adjustment: set the hole distance from the edge to 2.5, 4.5 or 6.5 mm.
- Tight 4:1 hole pattern: Φ 5 mm round holes with 6.35 mm spacing hold the coil firmly along the spine.
- Alignment clip: keeps the stack in line so every sheet is punched in the same position.
