20-High Rolling Mills for Very Thin Foils
20-High Rolling Mills for Very Thin Foils  Mills for producing products measuring 10 mm or less in thickness.
Unlike the sendzimir or lone type, the roll housing structure employed is a vertically split type supported by four posts.
This structure allows right-side and left-side independent or simultaneous adjustment of the roll gap with a press-down motor.
A powder clutch is employed for winding tension, which is capable of consistent tension control in a wide range.
