    • Unbeatable machine parameters

      A new innovative generation of PLUTO III slitter rewinders is characterised by an excellent price to quality ratio offering unbeatable parameters in a top range of models with high added value. Rigid construction guarantees maximum mechanical speeds of 600 m/min. The PLUTO III is available in 1,100 / 1,350 / 1,600 mm widths with maximum rewind and unwind diamter of 635mm and 1000mm respectively and minimum slit widths down to 25mm for 1000 kg roll weights.

    • Wide range of substrates

      Rigid construction, precise tension control system with closed loop, AC servo motors and a gamut of unwind and rewind tensions guarantee excellent processing on a wide range of materials including PP and PET from 10 microns, HDPE from 15 microns, LDPE from 20 microns and paper from 17 gsm.

    • Slitting techniques

      A variable knife shaft section permits tangential slitting with lower and upper rotary knives or with razor blades against grooved segment. For more difficult thin substrates it is possible to choose wrap around female knife slitting with rotary knives.

    • Servo drives

      An optimised solution with three AC servo motors and low energy consumption.The system includes main motor drives, drive and lay-on rollers, knife shafts and banana roller. An unwind AC servo motor in combination with a dance roller control tension and react to deviations in the material by braking or driving the parent roll. The third AC servomotor drives both rewind shafts.

  • Operator comfort

    • Shaft-less unwinding

      Shaft-less unwind with pneumatic chucks in combination with integrated roll loading through hydraulic tilting arms ensure easy roll handling and offer high efficiency and operator comfort during job exchange.

    • Automatic knife/blade positioning

      Automatic knife / blade positioning system ensures quick, precise and easy setting and reduces time during job changeovers (20 pairs of knives in less than 120 sec). This system is ideally combined with automatic laser core guiding.

    • Knife/blade positioning assistant

      The Knife / blade positioning assistant is an efficient solution for slitting and tool setting during job exchange. A touch screen control panel in the slitting section displays the knife/blade working parameters. Slit tool setting is easy and quick through integrated measuring scales within the knife shafts.

    • Automatic laser core guiding

      Automatic laser core guiding enables precise and very quick core setting for new jobs. The system uses common data with the automatic knife positioning system and provides an efficient solution for quick job exchange.

    • Unloading mechanism

      An unloading mechanism assists with heavy slit roll handling and increases efficency during the working cycle. An unloading arm delivers the finished slit rolls to a rotary stand. The hydraulic tilting rods are able to rotate in a horizontal or vertical direction.

    • Recipe system

      All machines are equipped with recipe system for storing of all working parameters as standard. Speed, tension, lay-on pressure, knife / blade setting and laser core guiding position information is stored in a touch screen display memory.

    • A vacuum splicing table with two pneumatic holders and back-lit desk enables easy and precise web splicing and makes for higher efficiency during job exchange.

  • Roll Quality

    • Tenzomat II tension control

      The Tenzomat II tension control system enables precise unwind and rewind tension control during the whole operating cycle in a closed loop. Deviation in unwind web tension from the required value is detected by a change of dance roller position. A control unit increases or decreases the braking effect of the AC servomotor prior to any effect on slitting quality. An advanced PID control system manages the slitting process of very thin and difficult substrates. Precise rewind tension control through PLC and tenso-meters measures real tension value at every moment of the operating cycle. These values are compared through software with pre-set tension value (calculated by internal algorithm) and any detected tension deviations are corrected by air pressure change under friction tapes in the rewind shafts. The friction force is converted by friction rings to tension in slit web strips. The friction rings guarantee precise distribution of the total tension to the web strips. The tension is calculated in kg per 1 meter of web width and converted via software according to taper curve with respect to the actual rewind diameter.

    • Banana roller

      An adjustable angle, driven banana roller with hard grooved segments is positioned before the lower knife shaft and significantly increases slit quality on poor substrates.

    • Eccentric roller

      An adjustable angle eccentric roller ensures web laying on the lower knife shaft during slitting of wrinkled material and improves slit quality.

    • Adjustable angle roller

      An adjustable guiding roller laterally balances the web and contributes to higher quality output during slitting from conical or low quality parent rolls.

    • Lay-on rollers

      Lay-on rubber rollers on tilting arms are fixed on a rod with spring-loaded segments ensuring perfect contact between lay-on roller and finished reel. For each rewinding shaft it is possible to set and automatically control tension according to finished reel width and diameter ensuring high quality rewinding.

    • Strip holders

      Strip holders hold the web in place and maintain the tension in slit strips during machine stop. The holders are automatically activated and deactivated at machine start-up for greater operater comfort, maximum use of time and higher quality slit rolls.

    • Torque rewinding

      Torque rewinding with pneumatic expanding shafts is an alternative solution to friction ring rewinding. It is mainly used for very narrow slit rolls of high quality materials where friction ring technology is not feasible.

  • Safety and Ergonomics

    • Intuitive control

      Touch screen control panels with user friendly interface in the rewind and slitting sections indicate error displays and settings of job parameters. An auxiliary control panel in unwind section ensures quick and comfortable handling of the input roll.

    • Machine design and ergonomy

      Aesthetic and ergonomic design with high quality surfacing of all machine parts. Reinforced sideframes ensure slitter stability for processing heavy parent rolls at maximum speeds.

    • Safety features

      Machines are designed with maximum emphasis on operator safety. All rotating elements in the slitting section are secured by safety covers and are inaccessible to the operator during the operating cycle. The rewind area is secured by a laser scanner.

    • CE standards

      Machines comply with and meet stringent European safety standards and codes. Operation and operator risk analysis are regularly assessed. Safety design features are updated and new ones added according to actual standards and code modifications.
