The unwinder is the place where the substrate is fixed. The attachment of the tube is performed through the use of an air gun or in some models is done in a button on the machine panel. The tensioning system in the unwinding is held by electro pneumatic brake (Altec).
Note: When using material with a width of less than 250 mm, place a tube on each side of the mandrel so that the ruler is not damaged early.
