Overview
Birlik Makina engineers and builds turnkey coil slitting lines for thicknesses from 0.50 mm to 12.00 mm. Our lines meet the strip requirements of tube and profile producers, steel service centres and sheet-processing industries with high speed and precision.
An optional second slitter head, automatic coil tilting and fast knife changes reduce downtime and increase capacity. The models below are standard; we design the line that fits your needs together with you.
Key features
- Optional second (double) slitter head
- Automatic coil tilting system
- Fast knife change
- High production capacity
- 7-roll leveller and edge control unit
- Two independent scrap winders
- Loop pit and separator discs for tight, even recoiling

Line units
Tap a card for details on each unit.
01 / 09
Coil Car
The unit where the coil to be slit first enters the line. The coil placed on the car is loaded onto the decoiler mandrel by this unit.
02 / 09
Decoiler
Continuously feeds the coil to the slitting unit. Heads moved by two opposing cylinders clamp the material, and the hold-down roll guides the strip to the next stage.
03 / 09
Leveller and Edge Control Unit
Corrects the deformed parts of the coil coming from the decoiler and prepares it for slitting. It consists of 7 levelling rolls; the first pair acts as pinch rolls. Vertical movement of the upper shaft is hydraulic, rotation is by a geared motor.
04 / 09
Guillotine Shear
The hydraulic guillotine shear, integrated into the leveller unit, cuts off the damaged head of the coil or cuts the coil at any required point.
05 / 09
Slitter Unit
Rotary knives slit the coil into strips of the required widths. The lower shaft is fixed and the upper shaft moves vertically. The slitter shafts are supported on three steel frames; the outboard bearing moves back and forth for easy knife loading. With the optional second (double) slitter head, the next knife set-up can be prepared while production continues.
06 / 09
Scrap Winder
The edge trim from both sides of the coil is wound by two independently operating winders, each driven by a geared motor.
07 / 09
Strip Tensioning Unit
Ensures the slit strips are wound onto the recoiler tightly and evenly. Strips leaving the loop pit reach the recoiler without tangling, guided by separator discs on an idler shaft.
08 / 09
Recoiler
Strip ends are gripped by a mandrel with a hydraulic locking mechanism and wound up; the mandrel diameter expands as it clamps. Separator discs on the overarm prevent strips from tangling. After winding, a hydraulic stripper pushes the coils onto the turnstile.
09 / 09
Exit Coil Car and Turnstile
As the stripper cylinder pushes the slit coils off the recoiler, the exit car supports them from below and carries them to the turnstile. The four-arm turnstile rotates on its axis by a hydraulic motor and brings the coils to a position where a crane can pick them up.

Frequently asked questions
Share your material, product dimensions and capacity target — our engineers will prepare a technical proposal tailored to you.
Which thicknesses and widths can the slitting line process?
Our standard models process coils of 0.50 – 12.00 mm thickness, 500 – 2000 mm width and up to 30 t weight.
What does the second slitter head bring?
With the optional second head, a new knife set-up is prepared on one head while the other is in production. Downtime from knife changes is shortened and capacity rises.
What does the line speed depend on?
Speed depends on sheet thickness and material grade — up to 220 m/min on thin gauges and 40 – 75 m/min on heavy gauges.
