VUC Series (Uncoiler)
Offers high-speed, good follow-up control,
and stable material feeding.
It works at high speed and has good follow-up control. The rotating section that winds and unwinds coils of material is driven by a servomotor, so that the feeder supplies the correct amount of material to match the press rotation speed in real time. Also, by installing a movable arm in contact with the outer surface of the coil, the radius can be determined and therefore the amount of material left can be controlled, offering remarkable stability while feeding.
Features
When a coil is attached to the setup side it takes 90 seconds or less to turn it to the production side, automatically insert it into the leveler, and then automatically pass the material through to the feeder.
Adopting our high-rigidity reducer in the mandrel drive unit. It permits a press hot start and provides stable opreration. This feature makes it possible to shorten the distance between uncoiler and leveler. It also contributes to space saving, Becase it doesn't need pits to make buffers.ร์

VSC/VLC Series (Loop controller)
The NC Loop Controller is a unique product developed to condition loop stock for material feeding by restricting the material's freedom of motion. No other device works the same way. Servomotors control the amount of rotation of the drive rolls while sensors and our dedicated servo controller stabilizes the loop into an optimum shape. This reduces flapping in all speed ranges. The material is delivered to the feeder without scratches, creases, or markings, thus improving the quality of the finished product and the productivity of the line. Small footprint design makes it easy to install.
Features
- Adopt high-resolution and high-torque servo motor.
- Eliminate bending of the material near entrance loop.
