  • Machine for treating metal sheets
    Patent number: 4209345
    Abstract: The machine comprises a lower frame and an upper frame which define an enclosure in which the cooling fluid flows and carry sets of sheet guiding and driving rollers. Hydraulic jacks are provided for, on one hand, shifting the upper frame relative to the lower frame and, on the other hand, maintaining the upper frame in position in opposition to pressure forces in operation of the machine. Additional support means (41, 51) are provided on each of the frames and are associated with an adjusting mechanism (42,44) for determining with precision the position of the upper frame relative to the lower frame.
    Type: Grant

  • Device for mounting rollers in a machine for treating metal sheets or the like
    Patent number: 4198994
    Abstract: The device enables the machine to undergo without damage the passage of deformed metal sheets or metal sheets whose thickness exceeds the gap between the rollers of the machine. For this purpose, the upper rollers carried by an upper frame of the machine are mounted in bearings which are supported elastically by means of spacer blocks. Sealing elements operating under conditions particular to each sealing element are provided. The main application of this device is in machines for effecting an accelerated cooling or hardening of metal sheets.

    Inventor: Alfred M. J. Germain
  • Machine for treating sheets of variable width
    Patent number: 4185648
    Abstract: The machine is designed mainly to effect an accelerated cooling of metal sheets and is improved in order to permit efficient operation with sheets of variable width. For this purpose, sets of elements forming baffles are disposed on each side of the longitudinal axis of the machine along edges of the latter. Depending on whether they are withdrawn into or not withdrawn into their housings, these elements modify the conditions of the flow of the cooling liquid in the machine.

  • Arrangement of the input and output ends of a metal sheet cooling machine
    Patent number: 4185649
    Abstract: In order to achieve a seal which is as effective as possible, there are provided at the input and output ends of a metal sheet cooling machine flaps such as flap (input flap) which are journalled in a frame of the machine to turn about an axis X--X and are actuated by jacks. Supports carried by a rigid girder ensure that these flaps do not buckle under the effect of the pressure forces created in the machine.
