Definitions

  • ABSTRACT Apparatus for winding knitted fabrics onto a beam or roll Aplll 29, 1968 Italy .3301 lA/68 comprises an endless conveyor feeding to a cylinder which is in peripheral contact with the growing roll of fabric on the [52] U.S.CI ..242/67.1,242/65,242/68.4 beam and also tangential to the endless conveyon As the [51] InLCl ..B65h 17/08 dia et r of the roll of fabric on the beam increases, the [58] Field of Search ..242/55, 56,64, 65, 66, 67.1, cylinder is pushed away from the beam and this actuates a control to move the conveyor away from the beam so that the conveyor and the cylinder and the periphery of the roll of fabric maintain their same general relation to each other.
  • the object of the present invention is to provide a machine for beaming fabrics of various kinds according to the chain system, as applied on the tenter frames, said beaming operation being performed in such a manner that the fabric width is constantly maintained under a dimensional control so that said fabric will be applied successively on the dyeing beam with a dimension predetermined by the operator and compatible with the fabric characteristics and having each of its selvages or edges well laid out and arranged exactly in a line.
  • the present invention solves the main problems of the beaming process, since it provides that the fabric is fed entirely spread on the chains and that it is caused to emerge from the grip of the chains and to wind on a rubber coated roller without any loss of continuity, said roller or cylinder acting against the effect of the winding unit so that it enables the fabric to be laid on the beam, maintaining said'fabric always guided and accompanied during the beaming operation so that said fabric can be wound with a predetermined width and having its selvages well spread and exactly aligned.
  • the peripheral speed of the fabric roll is always maintained constant either at the minimum or the maximum diameter.
  • FIG. 1 shows a diagrammatic side view of the beaming machine
  • FIG. 2 is a top view of said machine, partly broken away.
  • FIG. 3 is a fragmentary side view of the beam and its connecting and supporting means.
  • the machine comprises the entry frame head 2 for the fabric 1, said head being associated with a braking means 3 and a guiding loose roller 4; 5 is a platform for the operator.
  • the beam 7 is carried by the stationary shoulders 6.
  • the feed unit is pivotally mounted at 8 and comprises the shoulders 9, an idle cylinder 10, spreading rollers 11 driven at a variable speed and an idle cylinder 12 designed to control the amplitude of the wrapping arc of the fabric around the spreading rollers 1 1; 13 is a selvage opening out device for selvedge provided two, three or four rollers.
  • Across member 14 connects the shoulders 9 to each other, on said shoulders being mounted all the control devices; said cross member 14 serves also to carry the movable shoulders 15 of an endless chain conveyor device, said shoulders 15 being each articulated about a hinge 23 having a vertical axis.
  • Each of said shoulders 15 at its other end rests on the cross member 14 by means of a wheel 36 and can be caused to rotate about its hinge 23 by means of a screw 16 (according to the direction shown by an arrow in FIG. 2).
  • each screw 16 is engaged, is slidably housed in an elongated hole 37 in shoulder 15 in order to allow swinging movements of the pertinent shoulder 15 about its hinge 23, said shoulders 15 being able to be adjusted independently of each other.
  • the chains which may be of any suitable kind, the tensioning of which is controlled by an automatic tensioning device 18; at 19 is indicated a short rectilinear section of the chain length, and 20 is the driving shaft of the chains driven by gears 21.
  • the distance between the shoulders supporting the chains 17 may be adjusted by means of the big screws 22 for the purpose of obtaining the desired width of the fabric.
  • a driving device 25 designated to raise or lower the whole unit which feeds the fabric.
  • Said driving device 25 is pivotally connected to said base 24 as well as to the shoulders 9 so as to be able to transmit up and down movements under the control of control means.
  • Levers 26 are pivoted at 27 and carry a cylinder 28 which rotates in synchronism with the chain speed.
  • a device 29 is provided so as to act inresponse of the angular displacements of the lever arms 26 so as to impart a start signal to the device 25 so that this latter can cause the assembly to move away from the beam 7 as the diameter of the fabric roll on the beam increases.
  • FIG. 2 In the top view of FIG. 2 may be seen some of the structure as already described with respect to FIG. 1.
  • FIG. 3 shows a detail of means provided to clamp adjustably the beam 7, said means comprising a clutch 31 associated with gears which enable to adjust the clamping force acting on the beam 7, a shaft 32 carrying a worm screw, a spiral ring bevel gear 33 meshing with a helical rack, made integral with a clamping hollow shaft 34, said transmission enabling to transform a rotary motion of the spiral ring bevel gear 33 into an axial displacement of the shaft 34.
  • the assembly is driven by an electric motor not shown in the drawings.
  • the principle on which is based the present invention consists in the fact that the beam is mounted in a fixed position so that it does not transmit its weight, which increases the more and more fabric will be wound onto it and onto the other devices of the machine, and that the increase of the beam diameter moves a swinging cylinder 28.
  • Said swinging cylinder 28 feeds the fabric at the same speed as the chain 17 travel and also provides to take off said fabric from said chains, alwaysmaintaining itself tangent to these latter.
  • the increase in the beam diameter generates an angular movement of the lever arm which by means of the device 29 actuates a control device 25 which causes the feed unit to be moved downwards together with the chain system.
  • the swinging cylinder 28 always remains against the wound up fabric 1 so that in response to the diameter increase of the fabric roll on the beam 7 there occurs a downwards displacement of the assembly, thanks to the control device 29 associated with the levers 26 carrying the said cylinder 28.
  • Apparatus for winding fabric on a roll comprising a rotatable roll for receiving fabric thereon, an endless conveyor for feeding fabric in the direction of said roll, a cylinder that bears against said roll and is tangential to said conveyor and about which said fabric passes from said conveyor to said roll, said cylinder bearing peripherally against the fabric on the roll and having its axis parallel to the axis of said roll, means mounting said cylinder for movement away from said roll under the pressure of the fabric of increasing diameter on said roll, means mounting said conveyor for movement toward and away from said roll, and means responsive to said movement of said cylinder to move said conveyor away from said roll thereby to maintain said cylinder tangential to said conveyor.
  • said means mounting said cylinder comprising a lever arm pivotally mounted inter mediate its length and carrying said cylinder at the end and said responsive means at its other end.
