Abstract

This invention relates to a multifunctional machine for correction of flatness and tensioning errors in a disk-shaped blade (L), having a bearing frame (2) with locking means (3) mounted thereto for locking a blade to be corrected, sensor means (4) for detecting flatness and tensioning defects in the blade (L), at least one pair of pressure tools (5', 5') having an anvil (6) and a hammer (7) in facing relationship to each other for correcting defects on opposite sides of the blade (L). The machine is characterized in that it comprises at least two pairs of pressure tools (5', 5') having respective anvils (6) on opposite sides of the blade (L), the pressure tools (5', 5') being mounted to a single support element (8) to sequentially act on corresponding opposite faces (S1, S2) of the blade (L). The invention further relates to a method for automatic correction of flatness and tensioning defects in the blade, as well as to a computer program for controlling the machine and carrying out the method.
