Definitions

  • FIG. 2 CALENDER FOR DRAWING FOILS AND THE LIKE 0F SYNTHETIC MATERIAL Filed May 4, 1964 FIG. 2
  • Still another object of this invention consists in the provision of a calender as set forth in the preceding paragraph, which will make it possible to compensate for different bends of the rollers occurring as a result of different pressures in the respective bites.
  • FIGURE 1 diagrammatically illustrates a calender according to the present invention
  • FIGURE 2 more specifically illustrates a section through one of the stands for journalling the rollers of the calender and for adjusting the same.
  • FIGURE 3 is a horizontal cross section through one of the adjustable rollers.
  • the present invention is characterized primarily in that of the roller train, which may have four rollers, the last two rollers are angularly adjustable along a horizontal plane.
  • FIG. 1 shows the flow of the material M being processed into a foil.
  • the material is introduced into the bite 1 between the first two rollers I and 11 having their axes of rotation located in a horizontal plane.
  • the material then passes around a portion of the roller II into a bite 2 between the rollers II and HI the axes of rotation of which are located in a common vertical plane.
  • the material then passes over one-half of roller III on the right-hand side thereof (with regard to FIG. 1) into the bite 3 between the two rollers III and IV.
  • the axis of rotation of the roller IV is located in the same plane as the axes of the rollers III and II.
  • the material passes around the roller IV over the left-hand side thereof and leaves the latter over a roller or beam B from where it may be passed to a storage place, or the like.
  • rollers I, II, III and IV are journalled in two roller stands 4.
  • Each stand has a vertical chamber 5 with guiding surfaces 7 and 8 for guiding the vertical adjustment of rollers II and IV.
  • Stand 4 is furthermore provided with a horizontal chamber 6 having guiding surfaces 10 for the horizontal adjustment of roller I.
  • Roller III is not movable in vertical direction inasmuch as due to the heavy kneading operation, it is continuously pressed downwardly onto the sliding surfaces 9 forming a part of the frame portion defining the chamber 5.
  • the rollers. are provided with studs or trunnions 11-14 respectively, journalled in roller bearings 21 to 24 the housings of which are equipped with the required sliding shoes S.
  • the bearing housings of roller IV are movable in horizontal direction on a vertically movable bearing support 28.
  • the rollers III and IV therefore, may respectively be adjusted in opposite directions, as indicated by the arrows C and D or E and F.
  • the horizontal displacement of bearing housings 23 and 24 of rollers III and IV, as also shown in FIGURE 3, is effected by a fine adjusting mechanism 18 which is screwed onto the calender stand 4 and is provided with a driving motor 19 for roller Ill and with a driving motor 20 for roller IV.
  • the drives of both adjusting motors may run synchronously by engagement with an intermediate gear 27. However, if desired, they may also individually carry out different adjustments, in which instance the intermediate gear 27 is disengaged.
  • the adjusting movement is transmitted by spindles 25 and 26 respectively which engage corresponding nuts supported by the bearing housings 23 and 24. These nuts are carried by supporting members which are slidable relative to the housings 23 and 24 in corresponding slots provided therein.
  • the reference numerals 15, 16 and 17 respectively designate adjusting motors for adjusting the bite between the rollers I and II and the rollers 11 and III as well as the rollers III and IV.
  • These motors are, for instance through a worm and worm wheel drive, connected to spindles 29, 30 and 31 respectively which are connected to the respective bearing housings.
  • Connected to the respective worm wheel is a not (not shown), which meshes with the respective spindle so that rotation of the nut in one or the other direction results in a longitudinal movement of the spindle in one or the other direction and thereby in an adjustment of the adjacent bearing housing and the roller carried thereby.
  • the angular adjustment must be effected along a vertical plane and makes it possible, already at the start of the kneading operation, to afiect the course of the kneading material.
  • the adjusting mechanism may correspond fully to that for the rollers III and IV by the spindles 25 and 26 respectively except for being disposed vertically. Inasmuch as roller II is, under load, effective in two directions perpendicular to each other, it is necessary fixedly to arrange the said roller II. In other words, roller II cannot be angularly adjusted.
  • the present invention makes it possible to compensate for different roller bends and, more specifically, to compensate for each roller bend individually by corresponding angular adjustment of the respective rollers. Due to the fact that in addition to roller III, also roller IV may be angularly adjusted, it is possible additionally to influence the foil web as to uniform thickness.
  • a calender having a train of at least three rollers for drawing synthetic foils, in which material fed between the first two rollers in said train passes successively between said rollers until it leaves the last roller; means for supporting the last three rollers with their axes in parallel planes, and including means for angularly adjusting each of the last two rollers with their axes maintained in parallel planes, the means for supporting the roller next preceding the last two rollers maintaining its axis in a plane perpendicular to said parallel planes.
  • each of said last two rollers comprises individual adjusting means at each end of each roller for moving the corresponding end.
  • a calender having a train of at least four rollers for drawing synthetic foils, in which material fed between the first rollers in said train passes successively between said rollers until it leaves the last roller; means for supporting the last three rollers with their axes in parallel, vertically spaced, horizontal planes, means for angularly adjusting each of the last two rollers with their axes maintained in parallel planes, the means for supporting the roller next preceding the last two rollers maintaining its axis in a vertical plane, a drawing-in roller arranged horizontally of said next preceding roller, supporting means maintaining the axis of said drawing-in roller in a vertical plane, means for angularly adjusting said drawing-in roller with its axis maintained in a parallel plane, means to adjust said last roller and the roller next preceding the last two rollers vertically, and means to adjust said drawing-in roller horizontally.
