The slitting machine is used to unwind, slit and wind the metal coil into a coil with the required width. It is suitable for processing cold-rolled and hot-rolled carbon steel, silicon steel, tinplate, stainless steel and various metal materials after surface coating.

The equipment composition of the slitting machine train generally includes: uncoiler, guide device, uncoiler tension device, cutting head shear, feeding table, looper, disc shear, guide roller, machine train transfer roller, imported clamping device, constant tension Coiling device, edge shredding machine, scrap car, coiling machine, liner device, etc. The slitting machine train generally has the following forms:

1. Single entry looper slitting

In this type of slitting, a looper is installed in front of the shearing machine. There are centrally driven unwinding, tension unwinding, floating roller controlled unwinding, etc. to send the strip to the entrance loop. This method can realize micro-tension or zero-tension shearing, and avoid the phenomenon of shear blade slippage. At the same time, the uncoiler does not need a centering device, and the strip is centered in a looper.

2. Single export looper slitting

In this type of slitting, a looper is set behind the shearing machine, and the cut strip is pushed by the shearing machine into the tension-free looper between the shearing machine and the tensioning device. For thin strips, in order to ensure the stable unwinding of the strip during cutting, an entrance edge guide system may be required.

This method can effectively avoid the problem of unsynchronized winding of various strips caused by the thickness difference, and realizes the winding of the strip by controlling the winding tension. Due to the outlet looper, the strip can freely flow out of the cutting blade, avoiding the strip's wear on the cutting blade under tension and affecting the life of the cutting blade. At the same time, because there is no tension at the outlet, the phenomenon of necking of the strip is avoided. Single-export loopers are used more.

3. Double looper slitting

Double looper slitting combines two types of inlet looper slitting and outlet looper slitting. After the strip leaves the coiler before entering the shearing machine, it is fed into a free looper by the uncoiler or a pinch roller device or tension device, and the cut strip is sent to another after it leaves the shearing machine. Looper, and then enter the tensioner. Therefore, this type of slitting is called "double looper" slitting.

With this form of slitting, the slitting machine is only used to split the strip, thus eliminating the possibility of the strip slipping at the cutting edge of the scissors. This method neutralizes the characteristics of the single-entry looper and the single-outlet looper, and is suitable for cutting thin and soft strips.
