Description

Inventor: G. F. Raekett, Priority requested on April 24, 1942 (United States of Anterilea).

The present invention relates to a method of successively joining a multilayer film with several other films resp. bringing these into a superimposed layer, each film-arranged feed hall being successively brought into engagement with feed teeth on a bar member or conveyor belt.

In different procedures With the color film technique, it is necessary to successively combine different films, as mentioned above.

Thus, the sub-color images in the color film technique known in the blanking process on a glossy film are transferred successively, while the sub-color matrices are combined with it so that a composite film is produced. These sub-color films aro films, corn only simultaneously taken exposures of different color aspects of a seen, e.g. gala, purple and blagron components. It is also possible to use a multilayer film made of several emulsion layers which have been illuminated to varying degrees, and which are joined together by means of a transparent adhesive. It has been proposed here, after exposure and development of the film, to transfer these emulsion layers or some of them from the original film carrier to various separate film carriers to produce subcolor films of the above kind, the transfer comprising a successive ring of the separate film bars with the multilayer composite film. Rims isar.

It is possible to bring films together in such a way that the films are brought together on a breathless conveyor belt or other bar device, which is provided with teeth, which are suitable for feeding halls in the films and coin walking in a duck. These conveyor belts, which usually consist of metal, are usually manufactured with the utmost care and precision, so that it is considered guaranteed that all tandems are exactly the same and uniformly arranged on the conveyor belt. It nevertheless arises errors. In the case of in-line copying, the whole thing is that the superimposed copies of the sub-color matrices are not brought onto the composite film without contact with each other with a careful fit, which mediates color lashes and imperfect image sharpness. When transferring the emulsion or imager layers from a composite multilayer film to produce sub-color films, the error is that corresponding images in the image series on the sub-color films are left in the same relationship to their adjacent feed halls in the film. , whether by the ranking procedure or otherwise, the superimposed copies are not brought into a proper fit. It has been found that these errors are due to the variation in shape and condition of the conveyor belts of the conveyor belt.

The present invention has, inter alia, the object of overcoming the responsibility in question as regards the fit of the inboard and of achieving a perfect fit regardless of the inevitable lack of uniformity of the successive feed teeth along the conveyor belt or bar means with such a series of feed teeth.

The method according to the invention is characterized in that the films are fed to the conveyor belt in such a way that the feed halls in the different films, which have the same relation to the image series on these films, are brought into engagement with the same group of teeth in the conveyor belt.

Thus, the sub-color films are brought into contact with a multilayer film at successive stalls along the conveyor belt in such a way that the same group of peaks on the conveyor belt engage the corresponding abutment hall in the different films when one of the sub-color films is combined with the multilayer film.

When transferring the various layers of a multilayer film to other film carriers to produce partial color films, these film carriers are preferably fed to the conveyor belt at the successive stalls between the conveyor belt and the composite unit; and in the case of in-line copying of a composite film, the inatrices are fed to the bar member, preferably at the successive stalls, with the composite film between the bar member and the rest). the matrices. While the composite film can continue with the bar member past the aforementioned stables, the composite film is preferably fed to the Iran bar member with the usual sub-color film and Medal-es thereafter to the bar member with the next sub-color film.

The device for carrying out the conveying set according to the invention comprises an and-lost conveyor belt and means which set said conveyor belt in motion in a breathless path, said conveyor belt being provided with feed stands which engage in feed conveyor in the films and wherein means are present which feed the multilayer film and the other films on top of each other Superimposed layer on the conveyor belt in such a way that they feed the different films, which have the same relation to the image series, each time coming into engagement with the same group of peaks on the conveyor belt.

For the purposes of the illustrative drawing, the typical embodiments of the same are shown in the accompanying drawing, in which Fig. 1 is a schematic view of a separating apparatus for overlaying the image layers of a multilayer film into separate bars in order to provide partial color films. Fig. 29 is a sectional view taken along lines 2-2 to 99 of Fig. 1, with some parts broken away. Fig. 10 is a schematic view of an embedding copying apparatus, while Fig. 11 is a sectional view taken along line 11-11 of Fig. 10.

The pre-assembly seat and the device according to Fig. 1 were used to successively join a multilayer type composite film with other film carriers. The composite film is shown in Fig. 3 and comprises a conventional film carrier 6 with three emulsion layers 7, 8 and 9, the layer 7 being permanently applied to the carrier on ordinary sail, while the layer 8 there is applied to the layer 7 with an alcohol-soluble adhesive. and the layer 9 is applied to the layer 8 by means of a water-soluble adhesive. In some ways, the layer 9 can be loosened with a little help of water, without the layer 8 being loosened, after which the layer 8 can be removed, Won that the layer is loosened. Figures 6 and 8 show sections through the separate film bars 10 and 34, to which the emulsion layers are to be transferred, and which appear to be in exact superimposition with the film bar 6 and which film bars are ordinary cinematographic film bars. .

The special device shown in Fig. 1 comprises two drums or discs 11, over which a breathless conveyor belt or a carrier 12 is arranged, along the edge portions of which there are rows of feed pins or -Lander 13 (Fig. 2), which fit into the films. feed hall. While the pins can be mounted on the conveyor belt in different ways, they are preferably fitted in feed perforations in the conveyor belt which correspond to the perforations of the films, the pins being provided with heads 14 which abut against the back of the conveyor belt. Both the conveyor belt and the pins are suitably made of metal, the heads 14 being fixed to the back of the conveyor belt.

As shown in Fig. 1, the composite film 6 is fed into the machine from a spool 16, before the uncoated film carrier material 10 is discharged from a spool 17. The film 10 is then fed to the conveyor belt between a pair of rollers 18, which press the film into firm abutment against the conveyor belt with the teeth 13 projecting through the feed tail of the film. The composite film 6 is then fed to the conveyor belt between a similar pair of pressure rollers 19, which are arranged one above the other on each side of the film. During the passage to the conveyor belt, the composite film is fed through a water container 20 to soften the adhesive between layers 8 and 9, the lumen zigzagging back and forth over opposite pairs of guide rollers 21, so that the water has time to soften the adhesive in flake man but not sufficient for the layer to be displaceable before the composite film is brought into abutment against the conveyor belt. If the film can be expanded in a flake man by the action of the water, the carrier 10 is subjected to a similar treatment by being zigzagged back and forth over similar groups of rollers 22, so that the hot films are affected on the same salt. The conveyor belt enters the water tank and is led out UP through narrow slits, which allow only a small degree of varnishing, whereby the leaching water is continuously replaced from a suitable supply device. After the conveyor belt is discharged from the container, the films are pressed back together and against the conveyor belt by means of another pair of pressure rollers 23. When the conveyor belt pavers the movement around the disc 11, another rune 25 presses the film taken next to the belt. Along the curved part of the web of the conveyor belt at an angle of approximately 180 'of the periphery of the drum, the pins on the belt are frozen in the form of a fan, whereby the films are pressed closer together. After the films have been subjected to the liquid treatment and then pressed together on the belt, they also travel a sufficient distance for the upper layer 9 to line more firmly at the new carrier 10 than at the underlying layer 8, the layer 9 as a result of the pre-existing water treatment adheres to the new bar due to the sticky nature of the gelatin or the material which the layer otherwise consists of. When the movies walk together on the conveyor belt ,. the same is thus maintained with a careful fit with the pins on the belt, while the layer 9 is transferred from the composite film to the carrier 10.

After the layer 9 has become firmly attached to the new bar, the hada films are fed to the conveyor belt Over a roll 26 between a pair of rolls 27, where the hada films gave ice, the composite film 6 with its remaining layers 7 and 8 (Fig. 4) matas at hoger and the bar 10 with the layer 9 (fig. 7) maths at vanster. The film 10 winds back and forth Over paired guide rollers 28 In a drying chamber 29, until the film is dry, each of which is discharged to a take-up spool 30. The composite film 6 winds back and forth Over paired guide rollers 31 in the drying chamber and maths thereafter. Over guide rollers 32 and 33 to a second station, where the same is fed back to the conveyor belt to a carrier 34 Overlaid layer (Fig. 8), to which the layer 8 is to be transferred.

At the second station, a container 20 at the first-mentioned station corresponding to a container 35 is arranged to wet both the films on the same salt. If the layer is combined with the layer 7 by means of an alcohol-soluble binder, the container 35 contains alcohol. The blank film 34 is fed to the container from an output spool 36, then winds back and forth over paired guide rollers 37 and then mats to the conveyor belt between a pair of pressure rollers 38. The composite film 6 winds back and forth over paired guide rollers 39 and is fed. then to the conveyor belt in the carrier 34 superimposed between a pair of pressure rollers 40. After the conveyor belt is discharged from the container 35, the same passes between another pair of pressure rollers 41 and then under a pressure roller 42, then scratches around the left drum 11 and then along a path, which is sufficient forceps for the layer 8 to be firmly attached to the new carrier 34, after which the had films are fed from the conveyor belt Over the guide roller 43 to a pair of guide rollers 44, where they had the films go ice. The composite film 6 with the single layer 7 remaining thereon (Fig. 5) is fed left through the drying chamber 45 and then to the take-up spool 46 and the carrier 34 with the adhesive layer 8 (Fig. 9) is fed right through the drying chamber and then to the take-up spool 47. Thus, the composite film of Fig. 3 is converted to the partial color films shown in Figs. 5, 7 and 9.

The veneering copier shown in Figs. 10 and 11 comprises two drums or disks 51 with a tapered conveyor belt 52 similar to the belt 12 shown in Fig. the coil 56 through a water container 57 and then to the conveyor belt 52 between pressure rollers 58. The matrix 54 is fed from a coil 59 through a container 60, which contains a dye bath of the repellent color, is then passed through a washing container 61 to wash away the adhesive adhering to the film surface. Excess color, after which the matrix is passed through the water container 57 and then to the conveyor belt 52 between the pressure rollers 62. The coated surface 53 of the glossy film 53 is water from the conveyor belt, while the copy side of the matrix 54 is water against the transport hand, so that the hot films are pressed against each other. 62. After the films have been discharged from the container 57, press the same aters together by means of a pair of pressure rollers 63 and a single pressure roller 64. After the two films have wandered in contact with each other a sufficient distance for all the dye to be absorbed from the matrix to the blank film, both films are fed from the conveyor belt over a guide roller 65 and thereafter. between a pair of reels 66, where the hada films gave ice. The die 54 then winds back and forth across pairs of opposing guide rollers in the drying chamber 67 and then passes to the take-up spool 68. After the blank film 53 has wound back and forth between pairs of opposed guide rollers in the drying chamber, the same Over guide rollers 69 are fed to a another water container 71, the film titer being processed to accommodate a series of images, before the film returns to the conveyor belt between the pressure rollers 73. After the second matrix 55 has passed through paint and washing containers corresponding to the containers 60 and 61, it is fed through the container 71 to the conveyor belt 52 72. After the films have been discharged from the container 71, the same are pressed together again by means of the pressure rollers 74 and the pressure roller 75. After the films have passed in contact with each other along a sufficient distance of the conveyor belt path to effect the color transfer, r wool 77, where the had films run ice, the copied film 53 passing through the drying chamber 78 to the take-up spool 79, while the mandrel 55 passes through the drying chamber to a take-up spool 80.

The composite film 53 is sometimes printed with two series of images in complementary layers from the sub-color matrices 54 and 55. Instead of only two image series, three series can be copied in different sizes, in which case the conveyor belt in the form of a double loop can run over two pairs of discs, or three discs can be placed at the three horns of a triangle, so that the conveyor belt, when it passes from disc to disc, after every other scratches along the three sides of the triangle, a partial color film being fed to the conveyor belt along each of the Ire sides of the triangle.

Various detailed constructions for certain parts of the apparatus Aro schematically shown in Figs. 1 and 10 are shown in Patent No. 112,493.

In order to ensure that the film 6 or 53 comes into exactly the same position as the other films 10 and 34, or 54 and 55 each time two films are joined on the conveyor belt 12, according to the present invention the feed hole in the films is engaged with the same group of feed teeth on the conveyor belt. It is obvious that the feed hole in the film 6 is in a certain relation to the image series in the film, i.e. to the image number of the layers on the film, and that the image series of the layers transferred to the films 10 and 34 must have the same definite ratio to the feed hole in these films. Similarly, the image series on the films or matrices 54 and 55 have the same definite relationship to the feed hall in these films and the successive copies of these films or matrices on Millen 53 must have the same definite relationship to the feed hall in these rivets.

When according to Fig. 1 the films and Oro are fed to the conveyor belt 12, the feed teeth engage the transport hand in the feed hall in both films, sit that. the film 10 will be exactly superimposed on top of the film 6 for the transfer of the layer 9 to the film 10. Thus, the image series layer 9 has exactly the same relationship to the feed tail in the film 10, to which it Sr overlord, as it had to the feed hole in the film 6. The feed of the films 6 and 34 to the conveyor belt 12 are made in such a way that the same group of teeth on the conveyor belt 12, which intervenes in the films 6 and 10, intervene in the corresponding feed hall in the film 34, so that the film 34 is superimposed on 11 but 6 in exactly the same way as the film 10 was previously superimposed on top of the same film. The Under on the conveyor belt 12, which engaged in the feed holes in the Ada films 6 and 10, which limo coated adjacent to the first image in the image series A layer to be transferred, will thus intervene in the corresponding feed holes in the films 6 and 34, which aro coated next to the first image in the image series S layer, which is to be transferred to these films, and the same applies to Sven for each subsequent image in the entire series. In the device shown in Fig. 10, the same groups of teeth on the conveyor belt will engage in the feed hall in the films 53 and 55 fed to the conveyor belt 52, which groups previously engaged in the corresponding feed halls in the films 53 and 54.

In this way, the image series S the layer transferring to the carrier 34 has exactly the same distance to the feed hall of the carrier as the image series of the layer transferred to the carrier 10 has to the feed hole in this carrier. The image sequence on the hada films 10 and 34 thus has exactly the same relation to the feed hall in the films, which hal themselves have the same relation on the film, so that the series of images on the hada films come to exactly the same layer, if the It'd & films are combined. If these films are used as copy matrices in inline copying, I. ex. as copy matrices or films 54 and 55 in Fig. 10, the ones with these matrices successively challenge the copies on the film 53 in relation to the feed hall in this film, if the films 54 Mt 55 are successively superimposed on the film 53 by the same group of feed stands on the conveyor belt 52.

One way to identify the different pins Sr to apply numbers ph the conveyor belt, & Isom e.g. a number next to each pin or a number belonging to each group corresponding to the length of an image file. In practice, however, it is usually sufficient to simply mark out a pin or a pair of pin pairs by e.g. give this pin or this pair of pins a distinctive color, in which case each of the films can be fed to the conveyor belt in such a salt that this special pin resp. this pair of drops is in the middle of the first image of each movie. If its Onskas, the joint, dam conveyor belt hada spirits Oro torenade, can be used as a mark.
