Methods of determine the width of paper protector

San (Qingdao) Machinery Co.,Ltd | Updated: May 03, 2018


Q1: How to determine the width of the slitting paper roll or how to determine the width of L profile paper?


For inner paper: inner paper width = protector width*2 - protector thickness*2. For example, if you want to produce a 30*30*3 protector, the width of the inner paper is 54(30+30-3*2)mm.


For surface paper: surface paper width = inner paper width*2 + protector thickness*2 + 5mm (fixed value). For example, if you want to produce a 30*30*3 protector, the width of the surface paper is 119(54+54+3*2+5)mm.


Q2: How to get the width of U profile protector?


①For inner paper: inner paper width = protector height*2+protector width-protector thickness*2. For example, if you want to produce a 50*80*50*3 U profile protector, the width of the inner paper is 174(50*2+80-3*2)m.


②For surface paper: surface paper width = inner paper width*2 + protector thickness*2 + 10mm (fixed value). For example, if you want to produce a 50*80*50*3 U profile protector, the width of the surface paper is 364(174*2+3*2+10)mm.
