Rewinding unit

Two differential friction shafts on rewinders, OD 60mm, dynamicaly balanced, hardened flange Appropriate for friction rings of different sleeve diameters.

Roll diameter up to 620mm / 850mm

Max. roll weight on one shaft: 400kg

Digital tension control via I/P proportional pressure valve

Max. tension for both shafts in total: 400N (at min. diameter), 250N (at max. diameter)

Taper curve adjustable in 16 points (graphical representation on HMI)
Memory for 3 different “taper” characteristics

Lay-on rollers (EPDM rubber) for both shafts (automatically seaprately digitaly adjustable pressures)
Additional aluminum rollers (alternative to rubber-coated rollers)

Pneumatic clamping of slitted strips (while changing cores)
Automatic stop at set-length or set-diameter

Lasers for core positioning system on both shafts

Unloading stand with two mandrels, manually pivoting, length 1200mm
Two double bar rewind antistatic devices

Unwinding unit

Unwinding unit is completely separate from main machine unit

There is a safe pass between these two units for operator’s easy job setting and monitoring during run

Shafless, pneumatic activated, core chucks for 3’’ and 6’’ (76mm and 152mm) core I.D.

Roll diameter up to 1300mm
Servo driven unwinder perfectly maintains compensation roller in reference position (measured by precise linear magnetic encoder)

Digital tension setpoint via I/P proportional pressure valve

Tension range: 20-350N

Web break detection

Splice table after unwinder

Hydraulic roll loading (lifting)

Electromechanical roll axial gripping (frequency inverter)

Optional installation of a 100% inspection system

Slitting section

Razor slit in air/groove

Automatic vertical razor blade oscilating (moving up/down during run)

Manual knife positioning

Adjustable material height to female knife shaft Driven lower roller

Slitting section prepared for optional later installation of rotary knives system

Web line/edge guide

Web edge/line guide system after unwinder

Infeed section

Servo driven infeed rollers (S-wrap)
Siemens Sinamics S120 servo drive system

Bowed (banana) spreader roller (driven). EPDM rubber covered. Adjustable while running production

All idle rollers are cork-rubber (EPDM) covered and dynamically balanced

Fine leveling adjustment of the auxiliary roller before the S-loop (for improved material tension)

Operator controls

Industrial touch panel 12’’ for setting and supervision of whole machine
User interface: user friendly graphics, diagnostics and alarm messages, parameters, storage of unlimited number of jobs

Shift-based productivity measurement with storage of production statistics for several months
Rugged design for maintenance-free, continuous operation. IP65 front protection

Push-buttons with LED indication

Dodatni pult kod odmotača (sa BST komandnim panelom i komandno signalnim elementima)
