The powered, rubber coated snubber roll is 700mm long, with fixed arm.
A photoelectric cell is installed on decoiler to measure the Coil OD.


1.1

"EMG" automatic edge guide
with ± .5mm positioning accuracy

The edge guide system is with automatically-positioning photoelectric cell and proportional valves.


1.2

Spacers for decoiler mandrel drum

The spacers allow changing the mandrel drum expansion range to 470-520mm, for coils with 508mm ID.


1.3

Paper winder

This is for paper coils with a 70mm ID and a 400mm max. OD; and a 300 kg max. weight.
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.


7

Loop overcoming table

Hydraulically operated, it is placed at loop pit entry.


8

Strip tension felt-pad
& loop pit exit rolls

With 4 independent air pipes and hydraulic opening, the pad has a quick felt-replacement system (with "Velcro").


8.1

Separator shafts truck

Wih 2 + 2 positions.


8.2

Recoiling angle optimization roll

A vertically-mobile stell roll with 400mm diameter, Adiprene-coated.


8.3

Crop shear #2

See 3.1 ^


8.4

Pull pinch rolls
(rubber-coated)


With 400mm diameter, the pinch rolls work either in lieu of the felt-pad or together with it.
The upper roll positioning is powered and visualized.


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.


10

Interchangeable-mandrel recoiler
(mandrel changeover time: ca. 30 minutes)
with hydraulic mandrel support to assist rigidity

The recoiler has a 15 t capacity, with a 1800mm mandrel drum for 400mm Coil ID. The 8-segment mandrel is with no gap between two contiguous segments.
Hydraulic drum expansion & coil ejection plate.
Automatic clamping of the slit coil leading edges after mandrel expansion, with thickness-compensation system.
The motor power is 150 kW, AC with inverter.
Electronic tension-control system.
The hydraulic overarm is provided with rubber-coated rolls.
Automatic speed and winding tension adjustments.
Emergency brake independent from recoiler drive motor.
Photo-electric cell mounted on recoiler for the Coil OD measuring.

12

Strip hold-down for car ^
with "fingers"

Hydraulically operated, it allows off-loading the slit coils before strapping (if this is wanted).


13

4-arm turnstile
with total capacity: 60 t

The turnstile rotation is powered, with automatic centering every 90°.


13.1

Coil tilter
powered with air-operated coil clamping system
