C-Z Interchangeable Roll Forming Machine

Zipper closure 1/4 zip athletic pullovers for men. Stretchy, lightweight, fast-drying fabric for superior performance. REGULAR FIT - US standard sizes. An athletic fit that sits close to the body for a wide range of motion, designed for optimal performance and all day comfort. FEATURES - Quarter zip closure;Thumbholes on long sleeves to keep them in place during workout

C-Z quick interchangeable machine adopts a special structure. The rollers for C & Z are changed very quickly without dismantle any parts. One machine can produce all specifications of C & Z purlins. This machine adopts steel coils as material and gets profiled steel after the process of coiling, cutting, punching, and roll forming. Whole machine adopts PLC controlling, AC frequency speed regulating to fulfill the automatic production, which is very suitable for the metal cold rolled processing industry.
