Definitions

  • a film carrier transposes cut, [51] Int C12 B3lF 5/02 abutting film ends into engagement with half of the [58] Field 304 502 separated strip. Further movement of the carrier 156/505 506....5.(.). ].--216 227 258 causes the other half of the strip to be folded around the film ends to complete the splice.
  • the film it is necessary for the film to be reciprocated on a slide in order in one position to cut'the film ends to be joined together by means of one blade and in the other position to place the adhesive strip in position and to trim it.
  • the adhesive strip is placed in position entirely by hand, which not only makes the operation difficult, but also makes neat splicings difficult to obtain.
  • a technique of cutting and splicing photographic films and using perforated self-adhesive strips including the steps of supplying individual self-adhesive strips spaced apart on a carrier tape, cutting the film ends in a first position on a displaceable holder, applying a partially detached self-adhesive strip to the said ends in asecond position with the perforations thereof in register with the film perforations, and folding theedges of the strip over the ends of the film. Due to the fact that individual self-adhesive strips are supplied in a outdo-size state, trimming of such strips during the adhesion operation is unnecessary so that a considerable simplification of procedure and apparatus is possible.
  • the invention relates also to a film cutting and splicing apparatus simplified in the manner indicated above, including a displaceable carrier withholding pins for the ends of the film to be spliced, means wherebyv the carrier may be pivotally moved between cutting and splicing positions, the splicingposition having a magazine provided with individual self-adhesivestrips.
  • FIG. 1 is a plan view of .the apparatus according to the present invention.
  • FIGS. 2 and 3 are longitudinal sectional views through the apparatus of FIG. 1 in different operating positions thereof;
  • FIG. 4 is an enlarged partial sectional view through the splicing station of the apparatus
  • FIG. 5 is a plan view of part of the apparatus.
  • FIG. 6 is a section of a carrier tape with individual self-adhesive strips thereon.
  • the apparatus has a base 1, made of plastic material, on which the remaining parts are mounted.
  • a raised support 2 for the film ends to be joined together is formed on the surface of the base 1.
  • a slot 3 is provided into which a circular cutting blade 4 (FIG. 2) may enter.
  • the cutting blade 4 is mounted in the upper bifurcated end of a lever 6 on an axle 4', and the axial position of the blade 4 in the fork of the lever 6 is determined by spacing collars 4".
  • a handle 5 made of plastic material is removably mounted on the lever 6.
  • the lever 6 is pivotally mounted on a shaft 7 and normally retained in the rest position shown in FIGS. 2 & 3, by a spring 8, In such position the handle 5 rests against an edge of an opening of the base 1.
  • a generally flat holding-down spring 9 is secured to the upper end of the lever 6, the spring having a slot 10 through which the blade 4 passes.
  • a flat film carrier 11 On the upper surface of the base a flat film carrier 11 is mounted so as to pivot about an axle 12.
  • the film carrier 11 is provided with a cutout 13 in which the support 2 is reclined when the carrier is in the position shown in FIGS. 1 and 2.
  • the film carrier 1 1 Laterally of the support 2 the film carrier 1 1 has guides flanges l4 carring pins 15 for engagement with perforations at the two ends of the film to be joined together.
  • the film carrier 1 1 may be pivoted about the axle 12 through somewhat more than into the position shown in FIG. 3. There it strikes against a resiliently mounted support 16 which is also pivotable about the axle 12.
  • a lever 17 which is biased by a tension spring 18 is connected to the flat support 16 and the spring urges the support 16 into its upper position shown in FIG. 2, in which two lateral extensions 19 of the support 16 abut against the underside of the upper surface of the base 1.
  • the support 16 is provided with two holes 20 in which the inner pins 15 of the film carrier 1 1 can enter, when the film carrier 11 is pivoted towards the support 16.
  • an arm 21 is mounted to pivot about an axle 22.
  • the arm 21 carries a pressure roller 23 on its upper end.
  • the spring 18 also engages the arm 21 and tends to pivot this arm from the starting position shown in FIG. 2, which is determined by the roller 23 pressing against the support 16, in a counter-clockwise direction.
  • the splicing mechanism includes a magazine 24 made of plastic material in which a roll of carrier tape 25 is located, with individual self-adhesive strips 26 spaced apart and adhered thereto. Each strip 26 and the tape are provided with perforations 27 (FIG. 6).
  • the carrier tape 25 passes from the roll below a brake spring 28 outwards and around a sharp detaching edge 29 thence over the surface of the magazine 24 between a wall section 30 and the upper surface of the brake spring 28 to the rear end over two pins 31, which serve to locate the carrier tape accurately.
  • the magazine 24 is exchangeably inserted in the recess 33 of the base 1 by means of two lateral guide ribs 32. When the stock of self-adhesive strips is used up, this magazine is discarded and replaced by a new one.
  • the latter are placed on each of the guide flanges l4 and fixed on the pins when the device is in the starting position as shown in FIG. 2 in such a manner that the film ends overlap over the slot 3 in the required position.
  • the handle 5 is moved by hand to the right (FIGS. 1 and 2), whereby the hold-down spring 9 slides onto the film ends and presses them flat against the support 2 in the region of the slot 3.
  • the blade 4 now cuts through the two film ends, so that afterwards they are in flush abutment.
  • the cut off film ends are removed.
  • the handle 5 is now released and due to the action of the spring 8, returns to the starting position shown in FIG. 2, and the film cutting operation is terminated.
  • a self-adhesive strip is loaded onto support 16.
  • the carrier tape which is still suspended on the pins 31 by a pair of perforations, is raised and pulled out.
  • the band 25 is subjected to considerable tension over the sharp detaching edge 29 (FIG. 4) so that the next self adhesive strip 26 is here detached from the tape and projects in the direction of feed of the tape towards the edge 29.
  • Further movement of the tape 25 causes the detached self-adhesive strip to move over the roller 23 and onto the support 16 without becoming completely detached at its rear end from the carrier tape.
  • the carrier tape 25 is taken up until its next pair of perforations is just about to be engaged by the pins 31.
  • the spacing of the self-adhesive strips on the carrier tape 25 is such that on reaching this position the next selfadhesive strip 26 is located just below the edge 29 on the carrier tape 25 and projects beyond the roller 23.
  • the film carrier 11 is now pivoted clockwise towards the support 16 about the axle 112, so that the two film ends are brought into contact with the adhesive side of the positioned self-adhesive strip 26 as shown in FIG. 4.
  • the outermost perforations of the two abutting film ends are located exactly over the perforations 27 of the self-adhesive strip 26.
  • the perforations 27 of the selfadhesive strip are of larger dimensions than the perforations of the film, so that even with a slightly inaccurate alignment of the strip 26, no parts of the strip enter the perforations of the film ends; this would impair the film feed through a projector.
  • the self-adhesive strip 26 is folded around the edges of both film ends and pressed in position, and the splice is neatly completed. Neither the film nor the self-adhesive strip has to be handled manually at any stage of the process. It is pointed out that the support 16 and the film carrier 11 during the mutual downward movement just described, enter into a recess of the base 1, so that the film end parts and the ends of the carrier 11 projecting beyond the socket are able to move freely downwards. On completion of the splicing operation the film carrier 11 is released, so that the support 16 and the carrier are swung upwards under the action of the spring 18, until the support 16 has returned to its starting position. The film carrier 11 is now pivoted back to its position shown in FIG. 2, and the spliced film ends are lifted off. The device is again in the starting position and ready for another splicing operation.
  • a cutter with a straight cutting edge may be provided which can be swung down onto the film ends to be cut.
  • the movement of the carrier tape 25 could also be mechanised such that the feed may be effected by means of reciprocating tongs, rotary movement of a driving wheel, or the like.
  • the lever 21 may be formed at the upper end into a pressing shoe which replaces the pressing roller 23.
  • a film splicer comprising a base, a film carrier pivotally mounted on said base for movement between mounting and splicing stations, said carrier having guide means and pins for positioning film end portions in aligned and initially end overlapping relation, cutting means on said base at the cutting station and movable relative to said carrier for severing the overlapping ends of films mounted on said guide means to place the film ends in end-to-end abutting relation, support means on said base at the splicing station, a magazine on said base adjacent the splicing station for supporting a supply of individual self-adhesive splicing strips of a length greater than the width of the films, means on said base for feeding a single strip from said magazine onto said support means, said carrier cooperating with said support means to pivotally transpose said abutting film ends into engagement with one side portion of said strip at said splicing station, and means on said base responsive to further movement of said carrier for folding the other side portion of the strip over the edges of the films and pressing such portion into adherence
  • said cutting means comprises a circular cutting blade mounted on a pivoted lever adapted to be swung into position over the carrier.
  • Apparatus according to claim 2 wherein a fixed member is mounted on said base and wherein the carrier has a recess underlying the film ends and adapted to receive said fixed member, said member having a slot through which said cutting blade may project.
  • said folding means comprises a spring loaded roller responsive to pivotal movement of said carrier and said support means so as to enter into the recess of the carrier and roll over the abutting film ends.
