DSR RL with an integrated rear loading unwind
High Speed Slitting and Rewinding Machine with Integrated Unwind
The DSR RL accommodates the unwind and duplex rewind on opposite sides to allow reasonably large diameters in a layout which is incommensurately compact.
Designed to run at speeds upto 500 m/min, the DSR RL is thus a frontrunner where output per unit space is an important criterion during selection of equipment.
The specific benefits associated with the DSR RL include:
- Reasonably large unwind and rewind diameters in a compact layout
- Easy web threading
- One piece, pre-wired design with an integrated control cabinet to facilitate ease of transportation and quick Installation
- Speeds of upto 500 m/min
