Definitions

  • the invention relates to a method and an apparatus for assembling a cassette with an endless roll from a cut film tape.
  • a particularly inexpensive and space-saving arrangement is the continuous film, in which the film tape is transported past the image window for exposure via a channel between the core and the outer winding by a film transport engaging in the perforation.
  • the invention has for its object to find a method and an apparatus for the semi or fully automatic loading of a cassette with a loosely wound film tape, the ends of which are to be connected to one another by an adhesive strip to form an endless winding.
  • the advantages achieved by the invention consist in particular in that the film is now wound in accordance with its later position in the cassette, so that additional stresses on the film, such as occur in the winding shaft, are avoided. It was surprising to the person skilled in the art that, after the offset has been initiated, it remains intact during the entire winding process without further external intervention. Due to the multidimensional bend at the deflection point, the film is so stabilized in the shape that it maintains the direction it was taken, which was not to be expected due to the instability and the jumping ability of the film. Welter offers the advantage of the revolving winding chamber that every winding inserted is subjected to centrifugal force, which largely prevents the notorious swimming of the winding. At the same time, the rear wall of the winding chamber ensures that the individual turns are properly aligned.
  • the peripheral speed of the chamber at the deflection is greater than the feed speed of the film tape.
  • a shaping disc mounted on a shaft on the end face is arranged as a winding device behind a guide element, said shaping disc having a winding chamber with a channel beginning at the periphery contains, the inner change corresponds to the course of a cassette channel and the outer wall ends after a predetermined length in front of clamping elements that correspond in a certain position of the mold with an adhesive tape, and that a transport arm is movably arranged from the separating knife to the clamping elements and that there is an ejector in the molded disk.
  • the structure of the device is clear and therefore, in addition to the high level of operational reliability, it is particularly easy to maintain.
  • receiving elements for a cassette are arranged as a shaped disk.
  • the obvious advantage of this further device is that a shaped disk is no longer required, since it is wound directly into the cassette. In addition to the gentle handling of the film tape, the process of ejecting the continuous reel is saved.
  • the film tape 1 is drawn from the supply reel 2 via the loop puller 3 through the punch 4 around the deflecting roller 5 from the toothed drum 6 with pressing jaws 7 and through the separating knife 8 to cut the film of the molding disk 9 with offset fed via guide element 10 so that the film finally comes to rest after passing through the winding chamber 11 and channel 12 on the suction bores 14 formed as clamping elements of the shaped disk 9 after vacuum is switched on.
  • winding 11 is inserted into the winding chamber from the outside inwards.
  • the end of the film tape 1 which is now free through the separating knife 8, is brought from the toothed drum plane 6 in parallel into the plane of the shaping disk to the beginning of the film with the aid of a transport arm 16, where an endless film roll is formed by connection with adhesive strips by adhesive tape 17.
  • the finished film is pushed into the cassette (not shown) via ejector 18.
