Daco SR Slitter Rewinder

  • Daco SR Slitter Rewinder

The Daco SR slitter rewinder is a cost effective and simple to use label slitting and rewinding machine. The machines compact size and short web path keeps wastage to a minimum, the silicon covered nip drive roller helps to keep down time to a minimum as labels cannot attach themselves to the roller.

The Daco SR slitter rewinder has independent control of both the unwind and rewind tensions. The machine utilises rotary slitting with on the run lateral adjustment is fitted as standard and a splice table makes web splices both simple and quick. An electronic web guide with an ultrasonic sensor ensures that the finished rolls are perfectly slit and rewound. Pneumatic air shafts for both unwind and rewind means that changing the rolls could not be simpler.

Web widths 350mm (13.75″) & 430mm (17″)

Standard Features of the Daco SR Slitter Rewinder

    • Unwind
      • Maximum unwind diameter: 700mm (27.5″)
      • 76mm (3″) diameter air shaft
      • Merobel electromagnetic particle brake
      • Automatic taper tension control
      • End of roll function – The user is able to program the roll end diameter – slowdown and/or stop – The system does not use any roll followers or external sensors that can be damaged at roll changes. The diameter is programmed from the touch screen operator interface.
      • Web up – the operator can, at the touch of a button on the touch screen operator interface, release the unwind brake to allow for easier webbing up of the machine.
    • Splicing Table
      • 700mm (27.5″) inspection area prior to web guiding and slitting.
      • Adjustable splicing facility.
      • Pneumatic web clamps.
    • BST electronic web guide.
      • Ultrasonic sensor – enables guiding of opaque and clear materials.
      • Adjustable web guide sensor.
      • +/- 25mm (1″) correction.
    • Draw Head
      • Silicone nip roller against a driven draw roller.
      • The silicone nip roller does not allow labels to attach themselves to it reducing down time.
      • Fully adjustable to allow for different label stocks.
      • The draw roller is driven by a 1.5Kw (2 hp) motor.
    • Slitting
      • 3 quick set rotary scissor slitting knives (shear knife).
      • Minimum slit width: 13mm (0.51″).
      • Lateral knife adjustment: +/- 8mm (0.31″).
      • Dual knife box configuration to allow for razor slitting to be also fitted.
    • Rewind
      • 1 Product rewind.
      • Maximum rewind diameter: 360mm (14″).
      • 76mm (3″) diameter with quick change air shaft
      • Automatic taper tension control
      • Servo driven rewind
      • Labels in / labels out rewinding
      • Quick change air mandrels. The mandrel size is selected on the touch screen and is electronically compensated for, so there are no gears to change.
    • Count Facility
      • Labels
      • Linear – metres & feet
      • Stop on diameter
      • Total count
      • Batch count
      • Auto calculation of slow down and stop irrelevant of web speed.
      • TLC – Total length count until reset by the operator.
    • Colour Touch Screen Operator Interface
      • Shows machine status – system messages, interlocks not met etc
      • Quick and easy job set ups
      • Counting options
      • Tension settings
    • Speed – 250 metres / minute – 820 feet / minute – dependent on material.
    • Conforms to CE regulations and all circuits use dual channel safety switches, which are continuously monitored using a certified safety relay.
