  • the support means 23 is similar to the support means 22 described above but is built as a mirror" image thereof. This is done so that the support means 22, 23 may operate as a pair in supporting a core on 'v'vhiehv a reel of paper is to be wound, as will be described later. In other words the chuck 41 of the support means 22 and the corresponding chuck of the support means 23 may be inserted into opposite ends of the same core.
  • the support means 30, 32 are identical with the support means 22 and the support means 29, 31 are identical with the support means 23 so that the support means 29,30 and 31, 32 each form a pair between which a'reel may be supported.
  • the web 1 is to be slit into three equal width webs each of which is to be wound,
  • the machine operator moves the support means 22 to the position shown in FIG. 2 by operating the handle 52 which causes the pinions 50, 51 to rotate and roll along their respective racks 20, 21.

  • the tightness with which each layer is wound onto the reel has to be controlled, and the tightness of the reel is governed to a (e.g., extent by the nip pressure exerted between the surface of the reel being wound and the surface of the winding roller 5.
  • the nip pressure referred to above is created by applying a force to the carriages 39 which opposes the movement of the latter away from the roller 5. The magnitude of this force is dependent upon the air pressure applied to the cylinder 75 and a controlled leakage (i.e., a needle valve) in the pneumatic system, the pressure in the cylinder 75 being varied by means of the valve 81.
  • the nip pressure between the reel and the roller 5 is directly proportional to the pressure applied to the cylinder 75 for moving the carriages 39 towards the roller 5, and remains substantially constant throughout the period during which the reel is being formed.
  • the nip pressure does, in fact, decrease as the reel increases in diameter, due to the nip point moving upwards round the circumference of the winding roller 5. Due to the fact that the rails 37, 38 are horizontal the increasing weight of the reel has no effect on the nip pressure, so once the pressure in the cylinders 75 has been set, by the operator (the value of this pressure being dependent upon the type of material being wound) there is no need for it to be changed, unless of course the type of material being wound is such that, to obtain the best results, a greater decrease in nip pressure is necessary than is obtainable by the nip point moving as mentioned above.
  • This extra decrease in nip pressure may be obtainedeither by the operator reducing the pressure of the air being applied to the cylinder 75, by resetting the valve 81 at intervals during formation of the reel, or by controlling the valve 81 automatically by any convenient known means so that the air pressure to the cylinder 75 is progressively decreased.
  • CO represents the core
  • X represents the angle between the radius of the drum 5 through the nip point, indicated at NP, and the horizontal plane, indicated at PL, containing the axis of rotation of the roller 5.
  • the nip pressure needs to be of such a value that the web is tightly wound on to the core CO.
  • the angle X should be between and 60 and preferably between and .50", the actual angle chosen being dependent upon the material or materials to be wound.
  • said angle is determined by the layout of the machine, in particular the height of the rails 37, 38 above the floor 7 relative to the position of the roller 5, and also the diameter of the core C0.
  • the various dimensions are selected so that the angle X, at the start of reel formation is suitable for the material to be wound or, more commonly, a compromise between the angles required to give the best result for a variety of different materials. Any difference in nip pressure required which is outside that resulting from the chosen layout of the machine, is obtainable by suitably adjusting the air pressure appliedto the cylinder 75.
  • buttons 83 which operates a valve (not shown) which causes the air being fed into the cylinder tobe fed to the opposite side of its associated piston so that the carriages 39, and thus the reel R1, are moved to the left, as viewed in FIG. I, along the rails 37, 38.
  • This movement continues until the roller 40a engages the operating arm 43 of the microswitch 42, when the air supply to the cylinder 75 is interrupted and that the reel R1 stops in a rest position, adjacent that end of the rails 37, 38 remote from the winding roller 5.
  • the operator unclamps the support means 22, 23 from the slats l9, 18 respectively, by turning the knob 67 in the opposite direction to that when the base plates were clamped to their respective slats, as described previously, and moves the support means 22, 23 along the racks 20, 21 by means of their respective handles 52 away from the reel R1 so as to extract the chucks 41 from the core.
  • the reel R1 may then'be removed in any convenient manner and the support means 22, 23 returned to the position shown in full lines inFlG. 1 ready for a further reel to be wound in the same manner as described above.
  • This alternative way of extracting the chucks 41 from the core would preferably be used in cases where the next reel to be wound is to be a different width to that of the reel Rl.
  • reels R2 and R3 having different diameters when completed, are to be wound and lowered to the floor.
  • a core is positioned between the support means of each of the pairs of support means 29, 30 and 31, 32, the cores being moved into engagement with the winding roller 5 and the forming of the reels started, all as previously described with reference to the reel R1.
  • the machine is then started again and the web is wound on to the new empty core as well as the partially formed reel.
  • both the reels i.e., the reels R2, R3, have each reached the required-diameter
  • the machine is again stopped and the reels R2, R3 are each caused to be moved to a rest position by depression of the appropriate buttons 83.

  • the nip pressure across the width of the web may be varied by feeding air at different pressures to the cylinders 75 mounted in the support means between which the reel in question is supported.
  • the nip pressure is obtained by applying pressure only through the chucks 41 which are inserted into opposite ends of the core on which the reel is being wound. With this arrangement it is possible, especially in the case of reels formed from web of considerable width, that the nip pressure may be less towards the middle of the reel than at its ends.
