Definitions

  • the object of the invention to provide an improved calendar.
  • Adjustment of the gap between a first pair of rolls 1 and 2 is effected by raising or lowering the roll 1 in relation to the roll 2 through the intermediary of a gear box 5.
  • Compensation for deflection of the roll 1 caused by the passage of material through the nip of the rolls is provided by setting it obliquely in relation to the roll 2. This oblique setting is provided by gears 6 and 7. The deflection is small and takes place in each roll in a vertical plane. The obliquity of the roll axes is adjusted in a horizontal plane.
  • the gap between the rolls 2 and 3 is adjusted by the raising or lowering guides 8 and therefore both of the rolls 3 and 4 (second pair of rolls) are mounted in the guides 8.
  • the guides 8 can be raised and lowered through the intermediary of a gear-box 9, situated externally the guides 8.
  • a gear-box 10 acts as intermediary for raising and lowering the roll 4 independently of memn 3.
  • the obliquity of the roll 4 can be adjusted in relation to the roll 3 which lies above it in the guides 8. This oblique adjustment is effected by the gears 11 and 12 and takes place in a horizontal plane.
  • the invention is not limited to the I-formation four-roll calendar described and illustrated.
  • the invention can also be *applied for example to an F-formation calendar.
  • the calendar here proposed is pre-eminently suitable for coating corded materials on both faces, it being necessary for both layers of rubber or other coating material to be of the same thickness in order to obtain uniform thickness in the run of corded material. This can be achieved, however, only if compensation for roller deflection is provided by obliquely setting the co-acting rolls.
  • a first pair of rolls v I means for adjusting vertically the position of the upper roll of the first pair of rolls relative to the other roll of the pair, I a second pair of roll vertically adjustable guide means mounting said second pair of rolls whereby the gap between the lower roll of the first pair of rolls can be adjusted relatively to the upper roll of the second pair of rolls, means for adjusting vertically the lower roll of said second pair of rolls in relation to the upper roll thereof, and means disposed within the guide means for adjusting the obliquity of the lower roll of the second (pair of rolls in relation to the upper roll of the secon pair of rolls whereby to compensate for deflection of one roll of the first pair of rolls relative to the other.
  • a calendar according to claim 1 comprising means for adjusting the obliquity of the rolls of the first pair of rolls.
