Slotting and slitting method of slitting machine

Slitting machine is a kind of mechanical equipment that slits wide paper, mica tape or film into multiple narrow strips, and is commonly used in papermaking machinery, wire and cable mica tape and printing and packaging machinery. The slitting machine is mainly used in: non-woven fabrics; Mica tape, paper, insulating materials and various film materials slitting, especially suitable for narrow strips (non-woven fabrics, paper, insulating materials, mica tape, film, etc.).

There are three main cutting methods of the slitting machine, namely flat knife slitting, ring knife slitting and slotted slitting. These slitting methods have their own characteristics, and the following slitting machine manufacturers will take you to understand the slotting and slitting methods of the slitting machine.

As for the grooving and cutting method of the slitting machine, the principle is that when the material is running in the grooving roller, the cutter falls into the groove of the grooving roller, and the material is cut longitudinally. At this time, the material has a certain wrapping angle in the slotting roller, which is not easy to drift. However, grooving and slitting are common methods for cutting cast polypropylene films or narrow-edge films to improve slitting efficiency. Slitting machines rarely use the method of slotting and slitting, and generally use the first two methods.

In addition, in addition to the above three cutting methods, there is actually another extrusion cutting method, but extrusion cutting is not common in domestic slitting machines. However, because this cutting method can not only cut thin plastic film, but also cut thick paper, non-woven fabrics, etc., it is a more convenient cutting method, so it is a development direction of the slitting machine cutting method.
