Generally speaking, the smaller the blade Angle is, the sharper the blade will be and the higher the cutting precision will be. In addition, the smaller the blade Angle will reduce the work load of the knife rest and reduce the degree of wear and power consumption of the machine. However, the smaller the blade Angle, the better. Damage of the blade is too small, very easy to wear, especially in cutting some hardness is # # FormatImgID_0 thick paper can easily lead to bending blade damage to the blade, so learned through years of experience in papermaking machinery company 22 ° Angle of the blade is more suitable, and for some special hard materials, the use of the 22 ° 24 ° / double bevel blade, thus is advantageous to the cutting precision.
The knife pad is used to protect the blade and cut off the "backing paper" on the paper cutter. Experience shows that often after the new blade and knife pad, the first cut out of the paper quality is not good, may lead to paper under the edge is not smooth, or even cut constantly Kenny. Therefore, this requires a knife pad with good flatness. Knife marks can also determine the smoothness of the edge of the cutting paper, usually the depth of the mark is not FormatImgID_1# paper cut out of 0.5mm is relatively flat. Since the blade and the backing strip on the cutter will not remain absolutely straight, the strip will be placed on the back of the backing to achieve the desired "cutting" effect in order to ensure even cutting of the backing paper.
