Ⅰ.Use & Overview

The machine is used to cut pages from paper machine,calender and rewinder into sheet paper whose length and width is up to the standard.

The working principle of the machine is as follows:

The cutting length of the machine can be adjusted at anytime for sheet paper with all kinds of specifications.The Max.cutting length is 2880mm.designing speed is 150m/min;the Max.total weight of cutting is 1000gsm.Lead the page from unwinder or paper machine into longitudinal device through pick roll,after trimming deckle edge and slitting,the wed’s width meets the necessary requirement;then send the page into crosscut device through feeding roll;after transection,the web is to be sheet paper of certain specification.There is no carrier part between crosscut device and unwinder but with high-speed and low-speed belts ,rider belt,two loop polyester nets with separate transmission and combining device;make paper sheet overlapped mode and reduce into paper receiving speed to ensure paper receiver work normally during higher speed.After flapping of flap system,the paper can be place neatly; when coming to hight of paper receiving,fall the lifting table,paper pile can be removed,when paper receiver rises,paper receiving plate continues to receive sheet from convey belt,that’s the whole process of paper cutting.
