DSR FL 400 with an Integrated Front loading Unwind

High Speed Slitting and Rewinding Machine with Integrated Unwind

Slitting and Rewinding Machine with Front Loading Unwind

The DSR FL 400 combines in the same machine the Compact web path of the DSR RL 400 and the excellent accessibility / visibility of the ULTRASLIT OHP 500.

It differs from the DSR RL 400 in the location of the Unwind which is positioned on the same side as the Duplex Rewind (Front) end.

Besides the standard features accompanying all configurations, the specific benefits associated with the DSR FL 400 include :

  • Compact Web path and easy Web Threading.
  • One piece, pre-wired design to facilitate ease of transportation and quick Installation.
  • Minimum Operator movement.
  • Excellent access to the Cutting Unit and Trim extraction section.
  • The possibility of Inspection through Web Video or Stroboscope.
  • Speeds of upto 400 m/min

The DSR FL 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.
