Positioning drive shaft support for roller leveler

A roller leveler assembly, comprising:

• a first cassette comprising a first set of work rolls of a first diameter;
• a second cassette comprising a second set of work rolls of a second diameter;
• a drive mechanism which selectively drives one of said first cassette of said first set of rolls and said second cassette of said second set of rolls;
• said drive mechanism comprising a first set of drive shafts and a second set of drive shafts and a drive shaft support assembly, comprising:
• a first support shaft for supporting said first set of drive shafts, wherein said first support shaft comprises at least one first saddle and at least one second saddle for supporting said first set of drive shafts in first and second positions, respectively;
• a second support shaft for supporting said second set of drive shafts, said second support shaft comprises at least one first saddle and at least one second saddle for supporting said second set of drive shafts in first and second positions, respectively;
• wherein said first support shaft and said second support shaft are connected to and are driven by a drive gear assembly;
• wherein when said first support shaft and said second support shaft are rotated by said drive gear assembly, said first set of drive shafts laterally and vertically shift from said at least one first saddle to said at least one second saddle of said first upper support shaft and said second set of drive shafts shift from said at least one first saddle to said at least one second saddle of said second support shaft.

A roller leveler assembly, comprising:

• a first cassette comprising a first set of work rolls of a first diameter and a first spacing;
• a second cassette comprising a second set of work rolls of a second diameter and a second spacing;
• a drive mechanism which selectively drives one of said first cassette of said first set of rolls and said second cassette of said second set of rolls;
• said drive mechanism comprising a first set of drive shafts and a second set of drive shafts and a drive shaft support assembly, comprising:
• a first support shaft for supporting said first set of drive shafts and a second support shaft for supporting said second set of drive shafts, wherein said first support shaft comprises a set of first notches and a second set of notches for supporting said first set of drive shafts in first and second positions, and said second support shaft comprises a first set of notches and a second set of notches for supporting said second set of drive shafts in first and second positions, wherein said first and second positions of said first drive shafts and first and second positions of said second set of drive shafts correspond to said first set of work rolls and said second set of work rolls, respectively;
• wherein when said first support shaft and said second support shaft are rotated, said first set of drive shafts laterally and vertically shift from said first set of notches to said second set of notches of said first support shaft and said second set of drive shafts laterally and vertically shift from said first set of notches to said second set of notches of said second support shaft.
