For the Uniform Coil Strand Group
by Elaborate Machine Group Harmony
Entry Coil Skid
To avoid the line stopping when the overhead crane could not supply the coil on time, the coils to be slit are able to be laid on the saddles of this coil skids before they are moved to pay off reel by coil car. Coil skids are made of welded steel and mounted on the factory floor.
Entry Coil Car
Coil car is used to transport from coil skid to pay off reel and insert the coil into the drum in uncoiler.
Coil Opener, Loop Table & Pinch Roller #1
Coil opener opens the head of coil and guides it into the pinch roll, and upward unwinding is available. After the strip is inserted into the pinch roll, the opener blade is retracted and the table is lowered away from the strip. The coil opener will be supported in bronze bushings mounted to the No.1pinch roll frame. The opener blade will be mounted on the tip of the threading table.
Entry Crop Shear with Scrap Box
This entry shear will be used for cropping the head of the coil. Shear unit will consist of the moving top blade and the fixed bottom blade. Safety spindle locking pin will be provided for each shear knife to prevent the knife moving by accident when the line is abnormal operation or stopped for maintenance.
Side guide is located between entry shear and slitter. Side guide will be used to guide the strip and to adjust the center of line by AC geared motor. Side guide rolls will be measuring adjusted to center line controlled semi-automatic control system. The basic data of the product (plate width, thickness and any information) for adjusting of center line measuring received from PLC system.
The adjusted center line measuring method can doing controlled semi-automatic system with manual control system.
SLITTER Body & DRIVE UNIT
lit the incoming strip to the required width of multi-strands. Tooling makes the set up of tooling accurate and easier.
The slitter head slits the incoming strip into narrow strands. The slitting head with arbors hardened, grind and polished, running in dust sealed anti-friction cylindrical roller bearings. Simultaneous motorized arbor height adjustment will be done by push button with indication for as well as manual adjustment by means of handle and screw. The arbor rotates by AC vector motor through intermediate gear box and clutch. Lubrication of gear train is done by oil bath. Other parts are lubricated by manual grease gun.
TOOLING (Ø350) Rotary Slitter Knives
Made of special alloy steel equivalent to JIS SKD 11 heat treated with vacuum heat treatment operation and precise grinding.
TOOL CHANGING CAR
Grips the tail end of the strips when it passes out of the slitter head to prevent the strips end falling into the looping pit.
Apron guide provides the guide way for the strips at the exit of looping pit.

The separator will be provided in front of tension pad to guide every strand to their right positions which come up from looping pit. Keeping roll makes the strands kept in the right positions between spacers.
special steel, hardened and ground (JIS SUJ2 or SK5)
It is designed to give the strands uniform tension for tight rewinding on recoiler.
Hydraulic cylinder provides clamping force on mating felt covered on hardwood pads. Felt of special tear resistant type is covered on wooden pads.
The clamping force between pads is adjusted by regulating the pressure of hydraulic cylinder.

Recoiler & Separator
Provides tension to the slit strands and rewinds strands on the recoiler drum.
Separator #2 / Coil Pusher
Keeps the strands on their right position and to be wound on the recoiler drum correctly.
Prevents the deflection of the mandrel shaft of recoiler and reduces the Load on the main bearing of recoiler mandrel shaft.
EXIT COIL CAR
Is provided to take the coil from the Rncoiler to Coil skids and Two arm unloader, It travels on the rails fixed under ground pit.
EXIT COIL SKID
In order to avoid the line stopping when the overhead crane could not supply the coil on time, the coils to be slit, are able to be laid on the saddles of this coil skids before they are moved to pay off reel by coil car. Coil skids are made of welded steel and mounted on the factory floor.
