It is not needed to frequently adjust the clearance between the pressing rolls when pressing the sheet with different thickness, which can make the sheet come out from machine normally without scuffing of the coating film of the sheet. Being just like a ?oolproof camera? the operation of the machine is very simple. But the quality of the finished product can be guaranteed.


3. The length of the finished sheet is measured by the electronic measurement instrument or mechanical measurement instrument. The helping hand wheel and the counter are used in the adjustment of the bending of arch sheet, which makes the operation simple and guarantees the quality and the dimensional precision.
4. The hoisting tool is light and handy (The weight of hoisting tool of the United States is 30KG. And the weight of hoisting tool of our company is 2KG). It is convenient to install and uninstall the hoisting tool. Its hoisting speed is quick.
