How the coldfoil machine works? Let's figure it out.

this is the coldfoil machine working video of Shantou Huanan machinery company.The screen printing machine is from Shanghai Fengtai machinery company.
the coldfoil machine can print coldfoil/snowflake/wrinkle/UV solidify.
the most important advantage of the machine is jumping foil. The roller will rise up to stop runing film in these 2 setting situations 1:from paper to paper; 2:pattern to pattern in one piece of paper.
