DSR RL 400 with an Integrated Rear loading Unwind
High Speed Slitting and Rewinding Machine with Integrated Unwind
The DSR RL 400 applies the fundamental principles of the Duplex Center Differential Rewinding technique in an optimum manner to accommodate reels of reasonably big diameters on both the Unwind and Rewind side in a layout which is surprisingly compact and space saving.
The DSR RL 400 is thus a frontrunner where the Output per unit space is an important criteria during selection of equipment.
Besides the standard features accompanying all configurations, the specific benefits associated with the DSR RL 400 include :
- Compact Web path and easy Web Threading
- One piece, pre-wired design to facilitate ease of transportation and quick Installation
- Reasonably big Unwind and Rewind Diameters
- Speeds of upto 400 m/min
The DSR RL 400 can handle Flexible packaging substrates in their Plain / Printed / Coated / Co-extruded and Laminated combinations of base materials such as Paper (including label stock), Plastic films such as OPP, PET, CPP, PVC, POF and Aluminium foil.
