The function of the DRM 300 in it basic form is to salvage badly rewound coils produced on the Slitting and Rewinding Machine which would otherwise be liable for rejection due to reasons such as telescoping, loose winding and bad edge finish. The inclusion of this machine in the finishing section of a converting unit enables High speed and continuous operation of the Slitting and Rewinding Machine and its relevance is increasing with the rising standards of the Flexible Packaging and Converting Industry. The specific benefits and standard features associated with the WIR 300 include:
Cantilevered design for easy Web threading and fast reel changeover.
Air shafts for Unwind & Rewind units.
Air brake with reel diameter based automatic torque correction on Unwind.
Ultrasonic Edge Guide with a motorised actuator for the Unwind reel
AC vector drive technology with instant stop.
Pneumatically pressured lay-on roll for controlled rewind reel density
The DSR RL 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 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 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 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.
The DSR FL combines in the same machine the Compact web path of the DSR RL and the excellent accessibility / visibility of the ULTRASLIT OHP 500.
It differs from the DSR RL 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 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

A handy and invaluable machine for converting industry, the WIR 300 serves as a filter between the printing and lamination processes. The output of the Printing Machine is screened for printing defects such as mis-register, blade lines, shade variations etc. by means of a full width stroboscope provided as standard equipment. On request, a web video or a 100% defect detection system can be provided instead for more effective inspection.
The defective material thus identified is removed by cut and paste operations and only good copy is rewound to provide 100% defect free reels for downstream processes starting with lamination.
Another possibility is to edit a printed reel previously inspected and marked for removal on a printing machine equipped with an online 100% defect detection system.
Either way, the process not only ensures that there is no value addition on bad copy but also increases the plant productivity by making it possible to use its Lamination and Slitting facilities to their full potential without interruption.
The Web Inspection Rewinder WIR OHP 400 is an extension of the basic WIR 300 and features free standing unwind and rewind sections and an overhead path.

With a Free standing Unwind and bigger Footprint than the DSR RL and DSR FL, the ULTRASLIT OHP is conceived for higher speeds of upto 500 m/min. Its unique Overhead web path also offers better visibility and unhindered access that only such a configuration can offer.
Besides the standard features accompanying all configurations, the specific benefits of ULTRASLIT OHP include
A more hygienic work environment with reduced chances of contamination due to dust and insects. An aspect which is critical for the food and pharmaceutical industry.
The absence of the conventional platform between the Unwind section and the Main machine as also the location and orientation of the various functional groups such as the Line Position Sensor, Splice table, Skew roll, Cutting unit and Trim extraction section allow easy accessibility at a comfortable height both while Operating and Web Threading.
The area for visual inspection is at eye level with the possibility to incorporate Web inspection systems such as a traversable Camera or full width Stroboscope.
The possibility to incorporate features such as a Floor lift mechanism for the Shaftless Unwind roll and Splice table for Unwind reel changeover.
Speeds of upto 500 m/min.
