Large-Scale Coil Feeder Line
The large-scale coil feeder line supports high-tensile steel plates with stock widths up to 1,900 mm and stock thicknesses up to 6.0 mm. It also automates coil setting as well as midway cutting and rewinding of unwound stock. In addition to blanking presses, this technology is utilized in shear cut lines, and is well received by customers not only in Japan but around the world.
Features
-
- Straightener
This product supports a wide range of high‐tensile steel plates, which are experiencing increasing demand. Straightening is performed automatically (by setting data), and a wide variety of motor capacities are available to accurately meet customer needs for coil flatness. An opening mechanism (up to 300 mm opening) is provided as a standard feature to improve productivity for maintenance.
-
- Feeder/controller
For this product, we drew on our extensive track record and experience to provide optimal feed control. A measure roll (provided as a standard feature) also enables high feed accuracy. (PLC manufactured by Mitsubishi Electric; motor manufactured by Yaskawa Electric.)
-
- Automatic insertion (loading, peeling, threading)
An automatic coil threading function is included as a standard feature for the processes from loading to threading to meet customer needs for rationalization and reduction of preparation time.
-
- Other standard items
A hydraulic crop shear is provided as a standard feature, and a double skid car enables incomplete coils to be unloaded, allowing preparation for the next coil to be rationalized. A movable end feeder is also provided as a standard feature to enable coils to be used right up to the ends.

Note: The tensile strength is the reference value calculated based upon the yield point stress.
Check straightening performance in accordance with the yield point stress.
Note: Flatness may be unobtainable with the value in parenthesis.
