Roll Forming M/C with LM Bearing installed at the lower part of Stand is a manufacturing machine designed to be able to produce various widths of Strip automatically.   To shorten the time to replace Roll and to reduce the time needed to adjust Roll when each Roll is replaced, the assembled Stand & Roll is placed over the Stand & Roll in use. If necessary, the Roll can be replaced in a short time. This leads to an increase in productivity and an improvement in quality.
