Definitions

  • FIG. 7 ARRANGEMENT FOR GON'I'INUOUSLY HANDLING MOVING TENSIONED WEBS OF FOIL WITH FLANGED EDGES 3 Sheets-Sheet 1 Filed Jan. 28, 1964 FIG. 7
  • the concurrentlymoving guide ducts or slotted holding devices accommodating the flanges can be adjustable so as to diverge from or converge towards the travelling foil web in many known ways, this arrangement, moved by its own drive means towards the foil web, can also be used to stretch or to shrink foils provided with flanged edges.
  • FIG. 1 is a perspective view of the complete arrangement.
  • the guide channels for the flanged edges of the web, which travel independently with the foil web, are in this instance arranged on supports which are shown in a diverging position.
  • FIG. 2 is a side elevation, seen from the foil side of the arrangement, of two link chain drives having separate members which mutually engage and which together form travelling flange-guiding channels which loosely embrace the flanges of the foil.
  • FIG. 3 is a cross-section through the two chain drives arranged on a support, with those members which engage with one another and form the revolving guide channel.
  • each of the guide channels embracing the two flanges of the foil web is formed of a plurality of members separately fitting one above the other and arranged on two chain systems disposed in parallel one above the other.
  • the channel profile is continuously formed by the outwardly disposed surfaces of the members, which are located in pairs with their profiled surfaces facing one another, as the chain drives bring them into engagement. They are again separated from one another at the end of the chain drives and return again to the start of the endless chain drive.
  • the foil to be handled is indicated at 1 and this foil is provided with flanges 2.
  • the outside of the traction chain drives 3 and 4 carries bead gripping members 5 and 6 which, are respectively operatively connected thereto, such that when corresponding pairs of head gripping members 5 and 6 are in mating engagement with one another their head gripping surfaces cooperate with each other to define a longitudinally slotted channel.
  • Arranged on each side of the foil web are two cooperating chain drives 3, 4 (see FIG. 1).
  • the chain drives 3 and 4 carrying the members 5 and 6 that form the guide channel run over driven gearwheels '7 and are held under suitable tension by known means which are not shown.
  • the channel members 5 and 6 are built in with the actual chain links 8 to form a unit according to FIG. 3.
  • the links influence the cooperation of the members to form the channel.
  • the channel members 5 and 6 be pressed one against the other with a force which is suflicient to prevent the channel breaking open through the effects of the forces of the separately drawn foil 2.
  • the rollers 9 of the chain links 8 run on rails 10 over the entire region in which the channel is formed, the rails 10 transmitting the necessary pressure to the channel members 5 and 6 through the pins 11 by means of springs 12 and the screw 13.
  • Each channel member 5 of one chain drive 3 has a protuberance fitting into a corresponding recess of the channel member 6 of the other chain drive 4 with which it engages.
  • the housing 15 can consist of two parts, which are fixed by means of screws 17 to a common base plate 16, which forms one of the laterally pivotable supports arranged on both sides of the web.
  • the base plates 16 can be swung so as to be parallel, diverging or converging, seen in the direction of movement of the foil web and the chain drives. With very long chains, the rail 10 can be interrupted at intervals for the insertion of an externally driven gearwheel to relieve the chain of an excessive longitudinal tension accumulating through friction.
  • Suitable guide rails can be provided at the inlet end so as better to introduce the flange into the channel being formed.
  • the invention provides an arrangement for longitudinally moving a foil web 1 having flanged beaded lateral edges 2 by means of two pairs of endless traction drive chains, i.e. the two paired sets of chain link drives 3 and 4, which carry bead gripping members 5 and 6 such that, when passing longitudinally in mating engagement corresponding pairs of bead gripping members 5 and 6, with the bead gripping members 5 being carried by a drive chain 3 and the bead gripping members 6 being carried by a drive chain 4, pass longitudinally in mating engagement to grip successive longitudinal portions of each beaded edge 2 of the foil 1.
  • the foil 1 can be simultaneously subjected to lateral tension exerted across its beaded edges 2, with this tension being gradually varying or constant in the direction of longitudinal foil 1 movement, depending upon the relative orientation of the movement paths of its beaded edges 2.
  • the support members which can be regarded as the combination of the base plates 16 and housings 15, at an acute angle in relation to each other, the paths of the beaded edges 2 can be made to diverge to impart a lateral stretching tension to the foil 1, or to converge, and thereby permit the foil 1 to be shrunk to a reduced width.
  • the foil 1 be adapted to shrink by prior treatment, such as for example, where the foil 1 is fed to the apparatus under an initial elastically stretched condition, so that it will shrink laterally of its own accord as its beaded edges 2 converge. Otherwise, as will be obvious to the artisan, merely causing the foil 1 beaded edges 2 to move along convergent paths will only result in a foil 1 which hangs loosely between its beaded edges 2.
  • L'Arrangement for longitudinally moving a foil web having flanged beaded lateral edges which comprises a pair of elongated support members disposed in laterally spaced-apart relation to each other and oriented along predetermined lengthwise directions to define correspondingly respective longitudinal movement paths of the foil bead edges, a first pair of oppositely disposed endless traction drive means disposed in operative engagement with one of said support members for movement relative thereto along endless paths corresponding to the longitudinal movement path of one of said foil bead edges, a second pair of oppositely disposed endless traction drive means disposed in operative engagement with the other of said support members for movement relative thereto along endless paths corresponding to the longitudinal movement path of the other of said foil bead edges, and a plurality of head gripping members operatively connected to said traction drive means, said bead gripping members being connected in correspondingly equal numbers to each traction drive means in each pair thereof, with the bead gripping members connected to each traction drive means being disposed for mating engagement with the bead gripping members
  • said endless traction drive means are chain link belts and including a pair of guide rail members operatively connected to each support member, each of said guide rails being disposed in operative engagement with a corresponding chain link belt to urge the bead gripping members connected thereto into a selected position of mating engagement with corresponding bead gripping members connected to the oppositely disposed chain link belt in each pair thereof.
