Daco SVT350 Servo Driven Offline Turret Rewinder

The Daco SVT series servo-driven offline turret rewinder is a very flexible converting machine. The 4 spindle turret offers quick change over times, which coupled with a touch screen HMI operator interface makes the machine both interactive and user friendly. - (UK Patent Number GB2566694-A)


The Daco SVT350 modular servo-driven turret rewinder is a very flexible converting machine. The 4 spindle turret offers quick change over times, which coupled with a colour touch screen HMI operator interface makes the machine both interactive and user-friendly.

The operator can select from either length or a given number of labels per roll and the machine will then automatically cut and transfer the web to the cores without stopping.

The Daco SVT utilises a unique double-sided tape system (patent pending) for attaching the web to the cores, and the finished rolls are closed using a label printed by an on-board thermal transfer printer. This eliminates the need for expensive and complicated hotmelt gluing systems which often cause problems for both machine operators and end-users. Job storage, coupled with an intuitive touch screen control and minimal mechanical settings, makes the machine very simple to set up and operate.

There is a host of optional equipment which enables you to specify a very adaptable converting line both now and in the future because of its modular construction.

Standard Features

  • Web width: 350 mm (13.75”)
  • Unwind
    • Maximum unwind diameter: 700mm (27.5″)
    • 76mm (3″) air mandrel
    • Electromagnetic particle brake
    • Automatic taper tension control
    • End of roll function – The user can 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 guide
    • BST electronic web guide.
    • Ultrasonic sensor – enables guiding of opaque and clear materials.
    • Integral diagonal splice table with pneumatic web clamps.
    • Adjustable web guide sensor.
    • +/- 25mm (1″) correction.
  • Slitting
    • 3 quick-set rotary scissor slitting knives (shear knife).
    • Minimum slit width: 13mm (0.51″)
    • Lateral knife adjustment: +/- 8mm (0.31″)
    • Removable interlocked cutter guard for easy access to the slitting knives and anvils.
  • Servo driven 4 spindle turret rewind

    • Mandrel end support
    • 4 x 76mm (3″) air mandrels (or 4 of customer choice)
    • Adjustable core positioning stop – ensures accurate loading of cores onto the mandrel.
    • Automatic roll eject system complete with roll eject chute – enables easy removal of the finished rolls by the operator.
  • Print and apply label applicator to close the finished roll with a label.
    • A Toshiba Tec thermal transfer printer can print data to the roll closure labels. The printed labels are collected onto a vacuum head and applied to the finished rolls.  The label closure data is programmable from the machines touch screen.
