Definitions

  • a calender for effecting a progressive change in the camber of a dead or compression-loaded roll comprising a calender roll having a shaft extending from each end thereof. Journal bearings are provided for the shafts of the calender roll and bearing housings receive the corresponding of the journal bearings. The bearing housings are non-displaceable relative to the shafts of the calender roll. A displaceable bearing support is mounted on and concentrically surrounds each of the bearing housings. Means are provided for axial displacing of the bearing supports in order to permit adjustment complementary to the deflection of the calender roll.
  • the present invention relates to a calender capable of progressive adjustment of the camber of the dead or compression loaded rolls of chilled iron or steel.
  • Such calenders are employed for pressing, drawing and smoothing of thin sheets, in particular for the processing of textile goods, synthetic-resins of the thermoplastic type, paper or the like.
  • Rolls manufactured of chilled iron or steel have however the disadvantage for this purpose that they deflect under the operational pressure and thus do not ensure a uniform gap width over the whole of the length of the rolls.
  • the frequently employed camber of the rolls has the advantage that any given camber can be employed only for a working pressure dependent on the material to be processed, so that on the change of the material and also of the working pressure required, the previously employed rolls must be interchanged with others of suitable camber.
  • the interchange of the roll is, however, time-consuming and necessitates the provision of a large number of these expensive rolls with different cambers.
  • It is yet another object of the present invention to provide a calender comprising a roll having a support shaft at each end thereof, bearing means journalling each said shaft in axially-fixed relation thereto, a bearing housing mounting each said bearing means and displaceable support means carrying each said bearing housing, said support means being displaceable axially of the shafts to adjust the eifective support means of the roll.
  • the construction of the calender in accordance with the present invention has the advantage that for every change of the loading on the rolls the support bearings remain stationary at their position on the shafts of the rolls, the support bearing spacing being adjustable by stepless change of the camber of the rolls by means of adjustable roll deflection.
  • the displaceable bearing on the bearing housing which is preferably cylindrical, can be fixed at both sides by means of clamping rings.
  • an adjustment spindle is provided on this bearing, which can be adjusted by hand or mechanically by a hand or gear wheel keyed on the spindle.
  • a hydraulically or pneumatically operating device engaging thereon it is also possible to provide a hydraulically or pneumatically operating device engaging thereon.
  • the calender comprises a roll 6 manufactured of chilled iron or steel and is provided at each end with a shaft 9, for the support of which two spaced roller bearings 1 and 2 are mounted in stands 11. These roller bearings 1 and 2 are supported in a common bearing housing 3, which is of cylindrical construction.
  • Each bearing housing 3 carries a cylindrical ring 4 with a part-spherical outer surface in contact with a complementary surface of a bearing 5 and is displaceable to and from with the latter on the cylindrical outer surface of the bearing housing 3.
  • the displaceable bearing 5 is in engagement with an adjusting spindle 8, which is adjustable by means of a crank (not shown) or other mechanism, such as a gear wheel 10 by means of a motor (not shown).
  • the displacement of the bearing 5 can be effected by means o known hydraulically or pneumatically-operated devices.
  • the securing f the displaceable bearing on the hearing housing 3 is effected by means of clamping rings 7 which are disposed at both sides of each displaceable bearing 5.
  • the curvature and thus the camber of the roll can be changed because the displaceable bearings 5 can be displaced in relation to one another.
  • rolls with a predetermined camber.
  • the rolls are designed for the smallest dis tance between supports and the maximum pressure.
  • the adjustment of the joints of bearing support on the shafts of the rollers can be effected for example by fixing the clamping rings 7 on the side A of the bearing housing 3 and freeing the clamping rings 7 on the side B. Now the adjustable bearing 5 on the side B is brought by means of the adjustment spindle 8 into the desired new position.
  • a calender for effecting a progressive change in the camber of a dead or compression-loaded roll comprising a calender roll having a shaft extending from each end thereof,
  • journal bearing housings receiving the corre ponding of said journal bearings and having an outer peripheral face
  • bearing housings being axially non-displaceable relatively to said shafts of said calender roll
