Slitting machine flat knife cutting characteristics

- Dec 07, 2019-

Slitting machine cutting just like a razor, a single-sided blade or a double-sided blade is fixed on a fixed blade holder, and the knife is dropped during the running of the material, so that the knife cuts the material longitudinally to achieve the cutting purpose.


There are two ways to cut the razor:

One is slot Slitting cutting; the other is floating slitting.

The grooving slitting is when the material is run on the sipe roller, the cutter is dropped in the groove of the sipe roller, and the material is longitudinally cut. At this time, the material has a certain wrap angle in the sipe roller, and the drift phenomenon is not easy to occur. When slitting a PP film or a film with a narrow edge material, this slitting method is often used to improve the slitting efficiency. However, for the hanging and slitting, its disadvantage is that it is inconvenient to the knife.


Suspended slitting is when the material passes between two rolls, the razor falls to cut the material longitudinally. At this time, the material is in a relatively unstable state, so the cutting accuracy is slightly worse than the cutting, but the cutting is slightly different. The method is convenient for the knife and easy to operate.


The flat cutter is mainly suitable for slitting thin plastic films and composite films.
