Device and method for planishing metal product

A method for planishing a metal strip or plate product moving along a running path, the planishing implemented by a planishing installation comprising:

• a frame;
• a lower planishing cassette comprising lower planishing rollers and an upper planishing cassette comprising upper planishing rollers, the lower and upper planishing rollers disposed in the frame;
• a lower drive located and configured for driving rotation of the planishing rollers of the lower cassette;
• an upper drive located and configured for driving rotation the planishing rollers of the upper cassette;
• the upper and lower drives being disposed on a first motor side and external to the frame, laterally in relation to the running path;
• a secured assembly comprising the lower cassette and the lower drive;
• a displacement device configured positioned on the first motor side and operable to be activated:
• (1) to remove the lower cassette from the frame toward the first motor side;
• or (2) to insert the lower cassette from the first motor side into the frame;
• the secured assembly comprising a replacement tool for the lower cassette, the replacement tool being coupled to the lower cassette on a second operator side opposite the first motor side in relation to the running path;
• the method comprising:
• performing a first product pass in the installation;
• and
• performing a second product pass in the installation;
• wherein at least one of the first pass and the second product pass is an active planishing pass and the other pass of the first pass and the second pass is a planishing inhibited pass preceded by an activation of the displacement device for displacing the secured assembly including replacement of the lower cassette by the replacement tool in order to generate metal strip or plate processing different from the planishing pass.
