Metzner ST-OB
Compact and durable design for cutting harder or thicker material.

Compact Power for Versatile Cutting
The Metzner ST-OB is a compact cutter for cables, wires, shrink tubes, labels, rubber profiles and textile-covered tubes. Supporting punch, shear, draw, blade and tube cuts at up to 205 cuts/min, it delivers precise, damage-free results.
- Maximise productivityFeed rates up to 60 m/min with high short-cycle cutting for fast throughput
- Minimise waste & reworkRepeat accuracy within ±1 mm + 0.2% of cut length to reduce scrap
- Versatile functionalityQuick-change heads for die, shear and drawing cuts; one machine for many tasks
- Engineered for powerExceptionally powerful cylinder of 2,200N at 6 bar for demanding cutting tasks
- Operator friendlyIntuitive colour touch screen and PLC control for fast setup and simple training
- Safety ensured designBuilt to meet applicable European and UK safety standards for industrial use

Dereelers
Passive and active dereelers feed materials smoothly for consistent, precise cutting performance.
Flexible
Prefeeders
Work with dereelers to maintain a tension-free loop for precise, repeatable cutting.
Flexible
Loop Control
Control your feed rate digitally, to supply a tension-free product flow into the cutting machine.
