Definitions

  • the chain sprockets are arranged parallel to one another at the run-in location of the web (thus, the planes of the sprockets are disposed normal to the web plane). Consequently, the upper flights of the two chains are at the same distance from one another as the distance be tween the two lower flights.
  • the foil web to be engaged first runs with both edges onto the open clamping jaws and then it is guided by appropriate deflecting rollers in such a manner that the web edges are bent upwardly, whereupon they snap into the open jaws.
  • This manner of introducing the web into the open jaws carried by the chains involves the deformation of the web which is possible only in case of thin foils. In case of thicker foils such an introduction of the edges into the jaws becomes difficult if not impossible since a deformation of the edges. is resisted by the thicker foil. If the bending force is large enough, the edges would tear inwardly.
  • the sprockets of the two chains are disposed inclined with respect to one another in such a manner that the distance between the two parallel chains at the run-in locations on the sprockets is relatively only slightly larger than the distance between the chains at the run-out locations on the sprockets.
  • a web guiding drum there is rotatably supported a web guiding drum, the cylindrical surface of which guides the foil web along a path similar to that of the jaws.
  • FIG. 1 is an axial sectional view of the preferred embodiment at the run-in side of the web and FIG. 2 is a schematic side elevational view of the same embodiment.
  • the sprockets 2 and 17 support and drive an endless roller chain 18, while the sprockets 2a and 17a support and drive an endless roller chain 18a.
  • the upper flight 20 of the chain 18 extends parallel to the upper flight 21 of the chain 18a, while the lower flight 22 of the chain 18 extends parallel with the lower flight 23 of the chain 180.
  • the chains 18, 18a carry, respectively, a series ofjaws 6, 6a which are biased closed by associated springs and opened by the teeth of the sprockets. These jaws hold a foil web 5 at its edges so that the latter is maintained in a taut condition between the parallel upper flights 20, 21.
  • the sprocket wheels 2 and 2a arranged at the run-in side of the device are held in an overhung position on shafts 3 and 3a by means of ball bearings 4.
  • the shafts 3 and 3a are inclined at a fixed angle with respect to the horizontal so that the sprocket wheels 2 and 2a, in the lower range where the slack lower chain flight 22 or 23 arrives into engagement with the respective sprocket, have a greater distance from one another than in the upper range from which the upper chain flights 20 and 21 run off with the tensioned foil web therebetween.
  • each sprocket wheel 2, 2a is arranged at a small angle with respect to a plane that is normal to the web 5 in the zone of the sprocket wheels and is parallel to the direction of web travel.
  • the aforenoted angle is advantageously about 4. It is to be understood that the magnitude of this angle is an inverse function of the sprocket diameter to ensure that regardless of the dimensions of the sprocket wheel selected, the clearance between the lower portion of either sprocket wheel 2, 2a and the edge of the web 5 and the extent of its pro jection into the upper portion of either sprocket wheel 2, 2a do not change.
  • a foil web guiding drum 7 is freely rotatably held by a shaft 8 between the chain sprockets 2 and 2a.
  • the drum 7 has a diameter so designed that the foil web is maintained at the height of those angle members 19, 19a of the jaws 6 and 6a which are momentarily on the upper flights 20, 21.
  • the foil web pulled from a supply reel 9 is guided over deflecting rollers 10 and I l and is tensioned by a roller 24 supported on a swinging arm 12.
  • the latter is pivotally held on a shaft 13, which also carries the supply reel 9.
  • the deflecting rollers 10 and 1 l as well as the supply reel 9 are arranged in such a manner that the foil web 5 runs onto the drum 7 at a run-in location indicated at 14, which is situated approximately at the height the lower chain flights 22, 23 run onto the sprocket wheels 2, 2a.
  • the foil web is thus trained about the drum 7 approximately
  • the foil web 5 brought in the aforedescribed manner between the chains 18 and 18a enters the open jaws 6,
  • an apparatus for guiding a running foil web of indefinite length in a taut condition along a portion of its path of travel said apparatus being of the known type that has (a) two endless chains disposed and driven along either lateral edge of said web, each chain having two flights, the corresponding flights in the one and in the other chain running parallel to one another and (b) a plurality of jaws carried by each chain and engaging the adjacent edge portion of the running web at the run-in or upstream end of the apparatus and releasing said edge portion at the run-out or downstream end of the apparatus, the improvement comprising A.
  • first and two second sprockets each chain being trained about and supported by a first and a second sprocket, said first sprockets being arranged at the upstream end of said apparatus and each being inclined at a small angle with respect to a plane that is normal to the plane of said web and parallel to its direction of travel, the distance between said chains at the location of take-up on said first sprockets being relatively slightly larger than the distance between said chains at the location of run-off from said first sprockets, said second sprockets being arranged at the downstream end of said apparatus and B.
