uncoiler

The uncoiler in color coating line is also called decoiler, Pay off real, uncoiling machine, unwinder, unwinding coiler etc.. It is applied to line production for steel, aluminium and copper alloy mostly, such as cold/hot rolling mill, continuous pickling line, continuous galvanizing line, annealing line, slitting line, cut to length line , color coating line and so on.

In the color coating line, it equipped with two set single uncoiler or double-heads uncoiler at the entry of whole line to hold the coil on the mandrel. when the mandrel expands and rotates, the uncoiler tightens the coil and unwinds the strip to the next equipment. it feed the strip continuous during the line operation.

unocoiler and double-heads uncoiler
