Slitting machine round knife cutting characteristics

- Dec 09, 2019-

Circular knife slitting can be divided into tangential slitting and non-tangential slitting.

 

The tangential slitting is to cut the material from the tangential direction of the upper and lower disc knives. This slitting is convenient for the knives. The upper disc knives and the lower disc knives can be easily adjusted directly according to the slitting width requirements. Its shortcoming is that the material is easy to drift at the slitting, so the accuracy is not high, and it is generally not used now.

 

The non-tangential slitting is that the material and the lower disc cutter have a certain wrap angle, and the lower disc cutter falls to cut the material. This slitting method can make the material less prone to drift and high cutting precision. However, the adjustment of the knife is not very convenient. When the lower disc cutter is installed, the entire shaft must be removed. Round knife slitting is suitable for slitting thick composite membranes and paper sheets.
