The cross cutter is often considered to be the heart of a paper sheeter cutting industry. The cross cutter or just knife cuts the paper or board web transversally to the required sheet length. The unit consists of two rotating cutter knife across the full web width, with a blade mounted slightly oblique on each cylinder. The top and the bottom cutter knife are rotating against each other. A precise, accurate cross cut is crucial for the overall cut quality.
The paper sheeter production line need a high quality cutting edge,usually it requires the cutting edge HSS(SKH51) inlay before,With the development of welding technology,now we use carbide inlay cutting edge, it has much more sharp and durable performance by the carbide edge.but when the cutting length come to above 3000mm,the overall 3000mm carbide production is difficulty,so we usually make the carbide two parts jointing together welding on the knife body.last month,one of our customers satisfy it after the site inspection
