Looper

The looper is used to store the strip steel connecting the head and tail, so that the strip steel can be continuously transported for the unit during the head and tail butt welding of the coil, so as to ensure the continuous production of the unit, reduce the waste control loss caused by shutdown, and improve the production efficiency and product quality.

The front and back of the looper are equipped with a torsion frame to twist the strip angle. Two torsion stands are located in front of the looper to twist the strip to 30 ° and 60 ° respectively (the 90 ° direction is realized by the vertical pinch roll). A torsion stand is installed after the looper to twist the strip steel at the looper outlet to 0 degree
