Frequently Asked Questions

• How does the machine unload finished cylinders? The tilting bearing seat is opened after the upper roller is raised and secured, so the rolled cylinder can slide off the end of the upper roller.
• How are the rollers driven and adjusted? The main motor drives the two lower rollers through a reducer and gears, while an auxiliary motor raises and lowers the upper roller through worm gears and ball-bearing screws.
• What are the rollers made of? The three rollers are forged 45 steel with a hardness of HRC 35–45.
• What should I ask when enquiring? Ask for photos or video of the machine under power, whether an inspection can be arranged, which accessories are included, the condition of the rollers, motors and electrics, and the loading and shipping arrangements.
