横切机是瓦楞纸板生产线后段的一台关键设备，其作用是将成型后的见得纸板切断为一定范围内的任意长度，并且保证较高的切纸精度。挪切机的工作原理有三个基本点：（1）上下刀轴滚动剪切；（2）切纸长度取决于刀轴转速与纸板速度的比；（3）根切刀的瞬时城速度等于或略大于纸板 Crosscutting machine is a key equipment in the back of the production line of corrugated cardboard. Its function is to cut the formed cardboard into any length within a certain range and ensure high cutting accuracy. The working principle of Nissei machine has three basic points: (1) upper and lower knife shaft rolling shear; (2) cut length depends on knife shaft speed and cardboard speed ratio; (3) root cutter instantaneous city speed equal to or Slightly larger than cardboard
