Materials to be slit:

  • Paper-based / liner-based packaging laminates.
  • Board from 80 to 300 g/m².

Unwind section:

A separate between-centers unwinder, type T9, 1500 mm diameter, including:

  • Hydraulic cylinder control for lifting parent rolls from the floor.
  • Two motors driving the unwinding roll, controlled by an ultrasonic diameter sensor and a tension-control dancer roller.
  • Two pneumatic expanding adapters, SVECOM, for 70/76 mm (3”) cores.
  • Two pneumatic expanding adapters, SVECOM, for 150/152 mm (6”) cores (mounted on the pneumatic end adapters).
  • Floating edge-correction roller.
  • Automatic web guiding system, FIFE DP20, with SE26A photoelectric sensor, ±100 mm correction via electric actuator — for controlling sheet edge or continuous printed line.
  • Connecting walkway allowing web threading at floor level while keeping full access to the slitting station.
  • All web path rollers are anodized.
  • Safety guarding for operator protection.

Slitting section:

A slitting station with individual pneumatic knives and circular counter-knives:

 

  • Shear cut performed against the counter-knives.
  • Counter-knife shaft driven by an independent motor; counter-knife shaft is pneumatic.
  • Pneumatic knife holders mounted on a beam with a dovetail guide (TIDLAND) and an air supply manifold for individual activation.
  • 10 slitting sets, each including: Individual TIDLAND pneumatic knife holder (25 mm width) and double-bevel circular knife Ø 90/60 mm.
  • Set of multi-groove counter-knife rings, 5 mm pitch, 50 mm length.

 

Web separation section:

  • A separator roller driven by the slitting motor; angle and curvature fully adjustable.

Lay-on roller:

  • Lay-on roller made of anodized ground aluminum or polyurethane (depending on materials).
  • Pressure is adjustable and synchronized with winding diameter.
  • Roller is removable.

Automatic splicing / transverse cutting system:

  • Hydraulically operated pivoting arm including a transverse knife with linear motion and a backing plate for securing the web onto new cores.

Trim extraction system:

  • Trim suction unit with two width-adjustable nozzles.
  • Turbine enclosed in a sound-insulated cabinet, conveying trim to a centralized system or container (not included).

Rewinding section:

  • Motorized turret (two-position) supporting two rewinding shafts.
  • Rewinding shaft drive by an oversized asynchronous motor.
  • Hydraulic centering point for the active rewinding roll.
  • Two pneumatic expanding shafts Ø76 mm (3”), max load 600 kg each, equipped with full-width rubber strips with individual bladders.
  • Two pneumatic expanding shafts Ø152 mm (6”), max load 1000 kg each, also equipped with full-width rubber strips with individual bladders.

 

Electrical & pneumatic system

  • Main asynchronous motor
  • Electrical cabinet mounted on the machine side, connected by a 3-meter cable, housing motor drives and PLC
  • Main control panel including controls for braking, rewinding, emergency stop, lay-on roller, and auxiliary functions
  • 10’’ color touchscreen “DIGITAL PILOT”, providing:
    • Programming and storage of production parameters
    • Diagnostics and alarm management
    • Display of web tension (unwind & rewind)
    • Display of roll diameters (unwind & rewind)
    • Length counter with automatic stop at programmed length
    • Diameter counters with automatic stop at selected diameter
    • Adjustment of tension curves, core diameters, material types
    • Storage of up to 500 production recipes
    • Display of machine status and faults
    • PLC program monitoring for maintenance staff
  • Ewon® remote service (requires LAN internet access via RJ45)
