  1. Detail Information

This series nandles material form 600mm to 1,600mm wide and up to 6.0mm thick. The 11 work rolls offer an extraordinary level of flatness to the materials. The HL series featured that adapting all rolls driven with universal joint (MAC4-F) and strengthen body flame for straightening high tension materials. A straightener port opening mechanism has been added. allowing for improved maintenance and cleaning the rolls. The HL series underwent a new model for meeting the demand of both productivity and efficiency in pressroom.
