The entry coil car will be hydraulically actuated. It will be used to Traverse and load coil onto the mandrel of the decoiler.
To gain time while working, new coil is loaded to the coil car and lifted to the mandrel position by hydraulic lift and the coil car start to move horizontally let the mandrel go inside through the coil Then the loading car moves to the park position. Construction:
The coil car is a fabricated body of prime materials; mounted on hardened wheels and axles with spherical roller Bearing. The lifting face must be of ‘V’ shaped design. The cradle (i.e. V – Shape frame) is raised and lowered by four Colum steel and a hydraulic cylinders. The coil car traverse is accomplished by a electrical motor with a gear and pinion drive.
Technical Data:
 Type of Coil Car : rail Type
 Lift Capacity : 15 Tons (Max.)
 Lift / Lower function : By hydraulic cylinders with four Column 6.decoiler    Application: 
The decoiler can handle the coil and be capable of feeding the coil into the slitting Line, and also rewinding partially consumed coils, so they can be re-strapped whilst still on the mandrel, before returning to Coil Storage Facility for use at a later date. Construction:
The coil is handling and collapsed by double head. Steel fabricated duly machined, mounted on heavy duty shafts on anti-friction bearings. The individual body and the whole housing are fabricated by steel construction. 
Pneumatic controlled braking system is provided to minimize over running of the coil with tension. A brake is provided to stop the line whenever the line stops for any reason. Technical Data:
 Capacity : 15 Tons (Max.)
 Inner Diameter : Ø508mm
 expansion : hydraulic cylinder 
 Coil OD : 1500mm Snubber Roller (Guiding Equipment) The decoiler’s function is to take a new roll of metal and in a coordinated fashion feed the material into the pinch roll and shear. This is accomplished by a brake with a motor driving the deccoiler. When a brake is used, the material typically feeds via a thread-up motor directly into the pinch roll . Once the pinch roll has the material, the brake holds tension in the material and the motor turns off. The operator sets brake tension controls brake tension. A motor is used on the uncoiler, the material goes directly into the pinch roll as described above and the decoiler drive acts as both the thread up motor and the hold-back brake. Application: 
Anti coil break roll and guiding the coil to the slitting line. 
It will operate with the decoiler and the coil peeler to feed-up the coil end. The roll will be bear on the top of the coil, restraining the outer wrap and driving it forward.
A motor is driven Snubber Roller, (pressure roller) to prevent the coil from clock springing when the coil retention straps are removed. Grooves are required on the roll, to enable re-strapping of partially consumed coils when they are rewound on the mandrel. The roll will be capable of driving in both feed and retrieve directions.
Construction:
Snubber Roller is made out of Steel Pipe with suitable journals duly machined to be mounted on anti-friction bearings. The Roll is coated with poly rubber. roll is driven by electrical motor with chain & sprocket system. Roll and its Drive system is fitted on fabricated structure which in turn is mounted on the adjacent structure of Pinch Roll body. Actuation of arm is by hydraulic cylinder. 7.Peeler coil entry table Application: 
A hydraulically actuated peeling spade extending to the coil tongue on the Un-Coiler to “peel off” the leading edge of the coil and then retract to the Entry Pinch Rolls of pinch roll. This enables the operator to remotely thread the leading edge of the coil without having to manually handle the coil. The operator activates the positioning of the peeling spade at either end by hydraulic cylinders, actuated by “push button” controls.
Construction: 
Welded steel plate construction pivot mounted from entry pinch roll. Telescoping and positioned by hydraulic cylinders 8. Pinch roll Application:
A pinch roll with be provided to pull the strip from the payoff reel. The pinch roll unit will operated in conjunction with coil peeler to deflect strip into the shear and establish the entry pass line for payoff operation. Construction:
The body of the Pinch Roll is fabricated out of prime plates and machined to house the roll assemblies. 
Pinch rolls are provided to pull the strip from the coil mounted on the decoiler. Adequately sized pinch rolls are provided at entry of the shear to ensure that the sheet is not damaged by the pinching forces.
The pinch roll are capable of being lowered or raised during threading to accept the leading edge of the coil. The top roll must deflect the strip from Uncoiler to suit the pass line and actuate up and down by means of a pair of hydraulic cylinders. 
The pinching force developed by the hydraulic cylinders must present slippage between pinch rolls and sheet.
Rolls are driven via AC drives variable speed motor, gearbox, universal couplings. 9. Hydraulic Tip shear Application:

And a series of spacer rings precisely locate the slitter knives on each arbor. The machine cut the sheet width according to the spacer to adjust. Of course, the spacer has the thickness of specification, such as 5mm, 10mm, 15mm, 20mm, 28mm, 30mm etc. Slitting arbor material: we use 42CrMo steel, good process, quenched and tempered, processing, grinding and chromed finished and grinding again, etc. make sure the axle Non-deformation in the heavy working condition. Slitting head: the head and upper bearing seat are casting steel, the lower bearing seat is forged quenching and processed, a fixed housing and a movable housing to support the arbors / bearings and sleeves. Movable housing can be moved out using screw motor mechanism, for inserting slitter tooling as per the slitting schedule. The both arbors have the long key to lock the cutter.
The upper arbor is lifted by worm gear and motorize. Both the arbors are driven by motor through a gear reducer cum pinion stand and universal shaft.
The complete slitter head assembly as explained above is fitted on fixed frame grouted to the concrete foundation. 
The slitting head is a pair of rolls nipped together. These rolls have the knives in them that actually cut the metal. 
Power system: the slitting machine equip with motor, gear box and universal shaft to set up functioning. the slitter is driven by a thread-up variable speed motor that have looping pits and multi-modes of operation. Type : Round knife cutting.
