Coil weight : 5 to 30 ton.
Coil material : MS/HR/CR/ GP
Line Speed : 40 – 100 m/min.

3. LIST OF EQUIPMENT
 Coil rest saddle
 Coil moving carriage
 Snubber
 Uncoiling
 Strip pintching pressing and Leveling
 Side / center support
 Sheet cutting
 Slitter/Shear
 Coil inline separation device
 Scrap removing
 Looping device
 Coil tensioner and feeding device
 Coil rewinding
 Coil car

4. COIL REST SADDLE : This unit is placed at
the starts point of complete operation for
slitting. This coil is putted in to these saddles
through crane for support.
COIL CAR : This unit is placed underground
which is used to lift the coil for loading on
uncoiler center position. This unit is
machined properly guided on the guide rods
and bushes. Hydraulic Mechanism provide up
and down motion.
Capacity – 30 ton
Driven by gear motor

5. SNUBBER: Snubber roll device is placed on top of
un-coiler and when the coil is tighten in the uncoiler
this Vertical rollers help to presses the coil to rotate
with Uncoiler and move on pintching and leveling.
Pressing movement : By Hydraulic cylinder
Roller : 350 Dia .

6. UNCOILING : This unit is designed to take
capacity of 30 Ton coil. When the coil is bought
and tightened with the help of carriage ( coil
car).The single mandrel type coil inner diameter
and the movement is done Hydraulically. In
addition a break is also provided so that the coil
could enter according to the working manpower.

7. STRIP PINCHING PRESSING AND
LEVELLING: The unit can be centralized at
anytime with the help of our supplied design.
The design is capable of leveling and pinching
different thickness and width of welding
coil/strip ton its next operation of shearing and
cutting. Pintching /Pressing is done by
Hydraulic cylinder. Rollers are Hardened and
grounded special Alloys steel with antifriction
bearing and blocks.
Pinch /Leveler rolls : 07
Pinch roll press : By Hydraulic cylinder
Leveling press : By Hydraulic cylinder

8. SHEET CUTTING : The function of this unit is to
shear the strip from 0.5 mm – 6mm thick x 1600
mm. The shearing is achieved by two shear
blades bottom blade is in horizontal position. It is
fixed : top blade moves up and down and is fixed
on angular position with respect to horizontal
blades .The up and down movement of the top
blade is achieved with the help of hydraulic
cylinder and hydraulic power rack.
SLITTER/SHEAR : This unit function is to cut
primary coils into slitted coils. After the levelled coil
which is supported by center and side guiding
then its comes into the unit.

9. SCRAP REMOVING : This unit is used to take
out end strips fro the coil when it is Slitted by
shear. The speed can be adjusted it is been
conical design which can load the capacity till 1
ton with transmission mechanism and clutch
system.
The design is also made for the quick change of the
cutter as the stand is been automatically been
removed by hydraulic cylinder.
Cutter shaft and Material : Hardened and
grounded.
Cutter material and make : SKD 11 standard
make.

10. COIL TENSIONER AND FEEDING DEVICE:
This unit function is separate steel strip of
slitter.
Used break mechanism and Pressuring pad.

11. COIL SEPARATION DEVICE : The device is
placed on top of the Reeler/ Recoiler. When the coil
is been rewinding into the slitted coil. This device is
been pressed fitted with nitrile spacers and
hydraulic cylinder.
COIL REWINDING/RECOILING : The unit is been
uncoiled – levelled –slitted –tension with the help of
reeling shafts which rotate the shaft and rewind the
slitted coils with the help of a seperator device. This
unit drum which automatic collapse and Expends the
inner diameter of the coil with
the help of hydraulic mechanism with break control.

12. COIL CAR : This unit is used to lift the coil for
unloading on Recoiler center position. This unit is
machined properly guided on the guide rods and
bushes. The hydraulic Mechanism is provided for
up and down motion.
