The cutting stick is the counter cutting tool of the machine knife and should be made of a material which is tough, but not too hard. If the material is too soft, the knife will cut too deep. The lower sheets will not be correctly cut through. With an excessively hard material the knife will soon get dull or notches. The POLAR cutting stick meets these requirements perfectly.
Replacement or reversal of the cutting stick becomes necessary when the knife has dug into it up to a depth that the lowest sheets of a ream are actually torn instead of being cut. Every time the knife is changed the stick should be reversed or replaced. The consumption of cutting sticks depends completely on the materials processed. “The harder the materials cut the more sticks will be consumed”. Recommended value: The cutting
stick should be turned or replaced every 800 cuts. This increases the service life of the knives and prevents the edge from notching.
At the factory, POLAR installs cutting sticks that can be fully recycled and used with every type of knife. Especially for ultra fine grain hard metal knives we also use cutting sticks made of nylon. Due to the special properties of this material, only a very minor notch effect is caused during cutting.
