Definitions

  • the present invention relates to a tubemaking apparatus. More specifically, the invention relates to an apparatus for making tubes by helically convoluting strips of tape-material. Such apparatus, by virtue of its novel operation and simple construction, will increase the rate of tube production while decreasing the downtime resulting 4in conventional apparatus of this type from Separation of the strip convolutions and from other causes which will become apparent hereafter.
  • tubes by helically convoluting one or more strips of tape-material, and by thereafter suitably securing the convolutions together.
  • Such tubes find wide use in a variety of applications, for instance as a core on which rolls of various paper products are wound, such as wrapping paper and paper towelling.
  • a more specific object of the present invention is to provide a tubemaking apparatus in which relative diste t placement of the convolutions of the tape-material on the mandrel is prevented.
  • Yet a further object of the invention is to provide an apparatus of the type outlined above which will permit the use of tape-material of relatively great thickness without increased danger of relative dislocation of the convolutions formed by such tape-material.
  • Tube-forming means for forming on said mandrel an axially moving tube consisting of helically convoluted adhesive-coated tape-material;
  • FIG. l is a top-plan view of an embodiment of the present invention.
  • FIG. 2 is a View similar to FIG. 1, showing a lsomewhat diiferent embodiment
  • FIG. 3 is a schematic showing of a hydraulic drive means for use with the present invention
  • FIG. 4 is a top plan view of the drive means shown in FIG. 3;
  • FIG. 5 is an axial end view illustrating another embodiment of the invention.
  • FIG. l there is shown a mandrel 1 about which there moves a rotating tube 5 which advarices axially in direction of the arrow 5'. Convoluting of the tape-material about the mandrel l is not shown since in itself this is Well known in the art. This takes place in the tube forming means which is indicated in the drawing in FIG. l with a corresponding legend. Tube forming means capable of being utilized for this purpose is disclosed, for instance, in U.S. Patents 1,693,850 and 1,714,541.
  • a first pressing means comprising a pair of rollers 3, 4 which are respectively disposed on opposite sides of the tube 5, and are shown here to be located in a common transverse plane.
  • Guided around these rollers 3, ⁇ 4 is an endless belt 2 having two stringers, one of which passes by the tube 5 laterally thereof and substantially transversely of the axial extension of the tube ll whereas the other Stringer is convoluted about the tube.
  • the rollers 3, 4 rotate in direction of the respective associated arrows and consequently the belt Z travels in the direction indicated by the arrows provided thereon.
  • a second pressing means identical with the rst one is arranged spaced from the irst pressing means in axial direction ofl the tube 5.
  • the rollers of this second pressing means are designated with reference numerals 3a, 4a and the belt is designated with reference numeral 2a.
  • the spacing between the second and iirst pressing means will ⁇ be so selected that the time interval required for any given increment of the tube to travel from the iirst pressing means to the second pressing means corresponds to the period which the adhesive requires for setting, so that the adhesive will be completely or substantially set by the time the respective increment of the tube reaches the second pressing means.
  • the belt 2a of the second pressing means is provided not only for imparting a iinal compression to the convolutions of the tube 5, but also to counteract any forces which might try to separate the convolutions of the tube downstream of the lirst pressing means, for instance by axial slippage or by unwinding, and which could thus result in production of a damaged tube.
  • the provision of the second pressing means by reinforcing the compression of the tube convolutions While maintaining the convolutions against displacement, permits the production of a tube of much -greater resistance to bending or breaking.
  • rollers 3 of the first pressing means and 3a of the second pressing means are arranged closer together, as seen with respect to the axial extension of the mandrel 1, than the rollers 4, 4a of the respective pressing means.
  • the not convoluted Stringer of the first pressing means that is of the belt 2
  • the not convoluted stringer of the belt 2a of the second pressing means passes by the tube on a diametrically opposite side thereof.
  • other arrangements of the rollers and belts are possible, and
  • FIGS. 3 and 4 there is shown therein a drive means suitable for driving the pressing means shown in FIGS. 1 and 2. It is preferred that all rollers 3, 4 and 3a, 4a of the rst and second pressing means have a common drive. To this end each of the rollers 3, 4 and 3a, 4a is provided with a huid-driven motor 10. It is to be noted that the roller 4a is not visible in FIG. 3.
  • a gear pump 6 which is connected by a pressure conduit 7 with a feed conduit S communicating with the respective hydraulic motors 10 ⁇ of the rollers 3, 4 and 3a, 4a.
  • a return-flow conduit 9 in the form of a collecting conduit connectors the uid motors 10 and communicates with the gear pump 6, so that iluid fed to the motors 10 through the feed conduit 8 is passed into the return-flow conduit 9 and from there reaches the gear pump 6 for recirculation.
  • a bypass conduit 15 connects the pressure conduit 7 with the return-ilow conduit 9 downstream of the gear pump 6, but upstream of the feed conduit 8.
  • a pressure relief valve 5 is provided in the bypass conduit 15 and is so selected that it will open only upon Huid pressure in the pressure conduit 7 exceeding a predetermined maximum.
  • a shutoff valve 11 which permits selective opening and closing of the pressure conduit 7 and thereby enable selective establishing of communication between the pressure conduit 7 and the feed conduit 8.
  • This shut-oli valve is here shown as consisting of a rotary gate 13 which engages with its opposite ends arcuate wall portions 14 so that, as the gate is rotated in a sense in which both opposite ends engage the wall portions 14, ow of tiuid through the valve 11 is completely stopped, whereas, when the gate is rotated n a sense in which its end portions move away from the wall portions 14, flow of uid through the valve 11 becomes possible, with maximum ow taking place when the gate 13 extends parallel to the direction of ilow.
  • shut-olf valves of different construction are suitable zfor this purpose and that the one shown and described herein is mentioned by Way of example only.
  • the gear pump 6, which is designed to pump a somewhat greater volume yof fluid than is required for driving the motors 10, feeds the lluid through the pressure conduit 7 in the direction of the arrow. It the valve 11 is closed, pressure builds up in the pressure conduit 7 to a predetermined level. When this level is exceeded, the relief valve 12 opens and permits escape of iluid through the bypass conduit 15 and into the return-ow conduit 9. In the return-flow conduit 9, the fluid is prevented -from owing in direction towards the motors 10 by the check valves 15 which are installed in the conduit 9, so that the fluid must necessarily return to the gear pump 6. When the gate 13 of shut-olf valve 11 is slowly opened to an increasing extent, the fluid can pass from the pressure conduit 7 into the feed conduit 8 and from there into the fluid motors 10 which thus simultaneously and gradually are accelerated under full load conditions.
