Your client should think about our RA 5-25 unit instead. The relevant data sheet is attached. The WR 110 rolls can have a PET (plastic) sleeve with a rectangular groove. Should the material be straightened in two planes or just in a single plane? If a single plane straightener is needed only, please let us know if the rolls should have a groove with a width for the dimension 15.5 mm or for the dimension 22.4 mm
