Definitions

  • SHEET 2 [1F 4 APPARATUS FOR UNIFORMLY PULLING FORWARD INDIVIDUAL LAYERS OF A MULTILAYER WEB OF PAPER, CARDBOARD OR THE LIKE MATERIALS
  • This invention relates to an apparatus for uniformly pulling forward or feeding the individual layers of a multilayer web of paper, cardboard, and the like materials which emanate from several feeder rolls and are conveyed to a transverse cutter or some other processing machine with the aid of at least one pair of forward-pulling roller means which take up between them said multilayer web.
  • the present invention has for an object to provide a conveyor installation distinguished by simple construction and displacement-free mode of operation due to its straight line contact area.
  • the invention proposes to construct the roller means of the forwardpulling pair of roller means that take up or feed the multilayer web, in such fashion that they are equipped with a covering or jacket which encloses an air cushion and that the coverings come into straight line contact with the multilayer web in their operative conveying or feeding zone.
  • the forward-pulling roller means and the covering or jackets therefor are connected in such manner that they are not displaceable toward each other in tangential direction, but are displaceable toward each other in tangential direction, but are displaceable toward each other in a radial direction.
  • the construction is such that the facing air cushion enclosing surfaces of the forward-pulling roller means and of the associated covering or jacket are provided with intermeshing profile means.
  • said profile means are constructed as gear teeth extending axially over the entire forward-pulling roller means.
  • a further advantageous feature is to be seen in the fact that the air cushion located between the forward-pulling roller and the covering is connected with a hollow interior space provided in the forward-pulling roller means.
  • the invention proposes further to provide pairs of forward-pulling rollers which are pairwise enclosed by a cover or jacket for each pair, whereby the space enclosed on the one hand by the cover or jacket and its forward-pulling rollers and on the other hand by lateral sealing plates is formed as a hollow space which is connected to a compressed air source;
  • the installation can also provide for air tables on the inside of the sections of the covers or jackets conveying the plurality of webs.
  • These air tables are equipped with a plurality of air outlets which function as support means and whereby the interior space of the air table constructed as a hollow body is connected with a source of compressed air such as an air compressor.
  • the latter is constructed such that its operative surface is slightly arched.
  • FIG. 1 is a diagrammatic side view of a conveyor installation employing one pair of forward-pulling roller means
  • FIG. 2 is a fragmentary sectional view on an enlarged scale through the operative conveying zone of the forward-pulling roller means;
  • FIG. 3 is a view similar to FIG. 2 and illustrating the roller means during passage of a multilayer paper web
  • FIG. 4 is a fragmentary longitudinal sectional view through a facing side of a forward-pulling roller means
  • FIG. 5 is a diagrammatic side view of a conveyor installation employing two pairs of forward-pulling roller means
  • FIG. 6 is a cross-sectional view taken along line 6-6 of FIG. 5;
  • FIG. 7 is a view similar to FIG. 5 and illustrating an embodiment utilizing air tables
  • FIG. 8 is a similar view illustrating a modification of the conveyor installation depicted in FIG. 5;
  • FIG. 9 is a similar view illustrating a modification of the embodiment depicted in FIG. 7.
  • the individual paper webs 1, emanating from several feeder rolls not shown, are combined in the area of backing roller 2 which is mounted freely rotatable.
  • Conveyor means described further below convey the multilayer paper web 1 to the transverse cutter installation which is equipped with revolving knives 3 and which divides the multilayer paper web into individual sheet packages.
  • the cross section depicted in FIG. 2 through the operative conveying section of a pair of conveyor roller means shows that forward-pulling roller 4 which is constructed as a hollow body is provided with exterior gear teeth 5 extending axially of the roller 4.
  • the covering or jacket 7 made of elastic material, such as rubber, plastic or the like, has internal axially extending teeth 6 that mesh with said external gear teeth 5.
  • the diameters of roller 4 and covering or jacket 7 are selected such that an air cushion 8 is formed between gear teeth 5 of roller 4 and internal gear teeth 6 of covering orjacket 7.
  • FIG. 3 depicts the displacement of air cushion 8 after insertion of the multilayer paper web 1, by forming a straight-lined flattened zone 9 which determines the operative conveying zone of the pair of forward-pulling roller means.
  • the extent of displacement of air cushion 8 is thereby such that, proceeding from the middle of flattened zone 9 and decreasing evenly toward both ends, the straight line of flattened zone 9 and uniform pressure distribution are assured in this section.
  • the practically infinite diameter of the forward-pulling rollers in this operative conveying section is thereby determined and delimited by the contact of the tooth heads and shoulder of the internal and external gear teeth 5 and 6, said contact being caused by the displacement of air cushion 8 leaving no intervening space. Further this is enhanced by making the circumferential extent of the valleys between teeth 6 greater than the width of teeth 5.
  • FIG. 4 depicts the constructive features of the forwardpulling roller means in the area of their facing sides.
  • Head ring 11 is secured to axle journal 10.
  • Head ring 11 is rigidly connected with roller 4.
  • Axle journal also bears a terminal disc 12 which on its circumference is equipped with a flange carrying a sleeve 13 of rubber or the like.
  • An extension 14 of covering or jacket 7 is secured with bracing wires 15 on the circumferential surface of the sleeve I3 on terminal disc 12.
  • An 0- ring 16 embedded between bracing wires 15 assures sufficient sealing.
  • reinforcement threads 17 made of nylon are embedded in jacket 7 and extend circumferentially thereof.
  • Air cushion 8 enclosed between roller 4- and covering sleeve or jacket 7 is connected with the internal space 18 of roller 4 through bore 19, intervening space 20 and annular chamber 21. Air is fed through bore 22 located in axle journal 10, said bore 22 being provided with a relief valve not shown. Instead of utilizing compressed air for producing the air cushion, it is also feasible to utilize another gaseous medium or also a suitable liquid. It is understood that the other end of each roller is provided with a head ring, axle journal and terminal disc.
  • the conveyor installation comprises upper and lower endless coverings 23 and 24 and pairs of roller means 25 and 26 enveloped by said coverings.
  • the spacing distance between rollers 25 and 26 has been so chosen that the distance between coverings 23 and 24 corresponds to the thickness of the multilayer paper web 1 to be conveyed.
  • the space enclosed by coverings 23 and 24 is closed off by lateral or end sealing plates 27 and 28 in the plane of the frontal sides of rollers 25 and 26, said sealing plates at the same time serving as bearings for the axle journals 29 of rollers 25 and 26.
  • Support discs 30 are secured to the ends of axle journals 29, said support discs bearing on their circumferential sides the outside portions of coverings 23 and 24.
  • coverings 23 and 24 are equipped with a bridgelike profile sections or ribs 31 engaging within grooves 32 of sealing plates 27 and 28. Compressed air is fed through connecting extension 33 which is connected to an air compressor not shown.
  • FIG. 7 shows a simplified version of the embodiment shown in FIGS. 5 and 6 insofar as only one of the two coverings 23 and 24 is acted upon by compressed air.
  • the result of this measure is a slight arching of the operative sections of the coverings whereby the pressure needed for conveying the multilayer web 1 is produced by the restoring force of the section of the covering not acted upon by compressed air.
  • Apparatus for uniformly pulling forward the individual layers of a multilayer web of paper, cardboard or the like material emanating from feeder rolls for conveyance to a cutter or other processing machine comprising at least one pair of forward-pulling roller means cooperatively arranged on opposite sides of the path of movement of and engaging said multilayer web, each said forward-pulling roller means having an elastically deformable jacket therearound, means cooperatively arranged between said roller means and jackets to provide an air cushion internally of said jackets so that in operation said jackets make straight line contact with the oppositc sides of said multilayer web, and interengaging profile means connecting the jackets to the roller means, said profile means comprising interengaging external and internal gear teeth extending respectively longitudinally of said roller means and jackets throughout the operative feeding length thereof with the valleys between the teeth of one of said roller means and jackets having greater circumferential extent than the teeth accommodated in said valleys.
  • each said roller means includes a hollow interior chamber, each jacket being sealedrelative to each roller mans and the means cooperatively arranged between each roller means and jacket includes conduit means providing communication between said hollow interior chamber and the air cushion between said roller means and jackets.
  • Apparatus as claimed in claim 6 in which the means supplying compresscd air within both chambers comprises an air table within each chamber having an apertured side facing the associated jacket.
