This is a machine specially for bending the rolls with flat hot running system into helix-shaped heater. It is also applied to coiling and processing small-diameter tube electric roll heaters. The core shaft is driven by the step motor (the core shaft can be replaced). The core shaft is ingeniously equipped with air-powered clamp splice, which is to clamp the heater tube tightly with the pneumatic mechanism, and coil the heater tube in the direction of the axis. The machine has an automatic stripper mechanism, and is controlled by PLC with high efficiency.
