The expansion range of winder mandrel is 68.5-76mm. The mandrel expansion is air-operated; the winder drive is by AC motor.
The paper winding tension can be adjusted from control panel. Manual adjustment also possible.
2
Coil loading car
The car is of the "scissor" type with no floor pit. Has a 15 t capacity.
The up-down stroke is 650mm, the horizontal stroke (on rails) ca. 450mm; both, hydraulically operated.
Lateral containment bars are provided for narrow coils.
2.1
Static, 1-post coil storage car
Has a 15 t capacity.
3
Pinch rolls and telescopic table
The rubber coated pinch rolls have a 300mm diameter and AC motor drive; hydraulic lifting of upper roll.
Straightening rolls are also included for the coil leading edge.
The hydraulically-operated telescopic coil threading table is complete with vertical guiding rolls, having powered lateral adjustment.
3.1
Crop shear #1
Has blades with two cutting edges and torsion bar.
3.1-A
Scrap collection box
This is for max. 500mm long scraps.
4
Slitter entry guide
Has vertical guiding rolls with powered, mutually independent lateral adjustment; and an electric edge-control system, not requiring the use of the 1.1 ^.
The powered upper roll, rubber coated, is adjustable in height; the two lower rolls are fixed.
4.1
Plastic film rolls
and protection film [PVC] coil mandrel
These rolls are rubber-coated and air operated.
The mandrel expansion also air operated, with expansion range: 70mm to 78mm.
(Film coil max. OD: 400mm.)
5
Dual Head Precision Slitter
The slitter shafts are of 225mm diameter, high-precision machined, for 320<>350mm circular knives.
The upper shaft motion is powered, with shaft position visualized on control panel.
The clamping of knives is hydraulic, with hand operated pump; the clamping pressure is adjustable in relation to the material thickness and number of slits.
Slitter drive motor: 140 kW, AC with a special reduction unit.
Universal joints.
Powered traverse with 4500mm horizontal stroke; the slitter heads move on wheels, guided by rails, with an hydraulic auto.-locking system to 'work' position.
5.1
Felt-pad for slit coil "tails"
With air operated closing/opening of the pad upper section.
6
Scrap baler
AC motor driven, the baler mandrels are synchronized with the line speed.
The mandrel extraction is hydraulically operated, as well as the upper pressing roll.
Maximum bale dimensions: 800mm x 800mm.

8.5
Burr flattener
With heat-treated rolls, quick closing/opening and auto. control of the closing in relation to material thickness & strip width. Very high precision positioning.
9
Mobile frame
- automatic -
The 8^, 8.2^, 8.3^, 8.4^ & 8.5^ are mounted on a common mobile frame sliding on precision ball guide shoes, with hydraulic drive motor and position-control encoder.
The "mobility" allows keeping the strip-winding angle almost constant and helps the slit coils to go beyond pit, up to the recoiler mandrel.
