Abstract

The invention relates to a kmnote and it allows to improve the usability of the device and safety. In the case of the cutter 13, mounted on the guide 10, a safety flap 15 is placed in the plane of the blade 14. When cutting photographic material, the cutter is pressed until the roller 24 contacts the surface of the mounting table. As a result, the blade 14 is inserted into the groove 8. The flap 15 is secured by a latch 21, which is inserted into the opening 20 of the body of movement from the flat 1 1 to the cylindrical surface of the guide 10, causing compression of the spring 23. 3 sludge.

The invention relates to film photographic equipment, in particular, to devices for mounting a rolled photographic material, and can be used in other fields of the technique for rewinding, cutting and gluing rolled materials.

The purpose of the invention is to improve the operating conditions and safety.

FIG. 1 shows the device plan; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2

The device for rewinding, cutting and gluing the rolled photographic material includes a housing 1 in which identical light-tight chambers 2 with lids 3 are made to stir the receiving and feeding coils 4 with the photographic material 5. The receiving coil 4 is kinematically connected with a mechanical drive 6. Between the chambers 2 there is an assembly table 7 with a shell 8 and an opaque cover (not shown), as well as a cutter 9 mounted on the guide 10 for movement along it and turning around it. The guideline 10 is fitted along the entire length of the bald 11 and is rigidly fixed in the lugs 12 of the lid 3. The device also contains a reel with adhesive tape, its stitching elements to the photo material when gluing and trimming the ends of the adhesive tape after stitching (not shown). The cutter 9 consists of a housing 13 to which a removable blade 14 is attached (e.g., a safety razor blade). The safety shutter 15 is housed in the cutter body in the plane of the blade, attached to the cutter body by means of the axle 16 and communicates with the spring 17, which is rigidly fixed at one end to the cutter body and the other abuts the safety shutter. In the shutter 15 there is a groove 18 in which the stop 19 is rigidly fixed in the housing 13 and the opening 20 for the clamp 21. The latter is made in the form of a pin and is placed in the opening 22 of the housing 13. In the opening 22 also a spring 23 is placed, one end which rests on the torch body, and the other presses the pin of the retainer 21 against the surface of the guide 10. On the body 13, there is also mounted a support roller 24 rotating on an axis 25.

The device works as follows. Open the table top cover (not shown). Open the lids 3 of the light-tight chambers 2 and install the feed (with photo material 5) and take-up coils 4 into them. Fix the end of the photo material 5 on the take-up coil and close the covers of the device. By rotating the handle 6 of the drive 6, the required amount of photographic material 5 is rewound onto the bottom of the table 15 with the surface of the table 7. In this case, the latch 21 pushes the spring 23 out of the hole 20 ki 15 and rests against the shoulder 11 of the straight line 10. Pressing the cutter 9 to cut the photo material until the face 24 is in contact with the surface of the assembly (or with photo material 5) and extending along the guide 10. When cutter 9 its body 13 with the blade 1 has overcome the force of the spring 17, shifted down relative to the shutter 15 and will go into the groove 8 Upon completion of pressing the cutter 9, the spring 17 will rotate to resting the upper edge of the groove 18 in a and the lower edge of the curtain lowers the cutting edge of the blade 14. For the cutter 9, it is rotated to the initial position around the guide 10, this retainer 21 will move from the cylindrical surface of the straight 10 and compress the spring 23 to enter 20 curtains 15, fixing the position relative to the housing 13.

Claims (1)

The proposed device also makes it possible to produce a scraper of a forial with subsequent rewinding, the placement of the cutter on the lid of the illuminated camera and the presence of a protective curtain ensures the operating conditions, which increase the ease of handling and prevent cuts in the darkened room. Invention Formula A device for peremogka, cutting and vanishing of rolled photographic materials, with opaque opaque cameras with coils for photographic material of the coil actuator base, mounting with a lid, a cutter, made in the form of a body with a blade, which appears on the guide with an edge, and rolling elements and About the adhesive tape, which is designed to increase the convenience of use and safety, the cutter is supplied with a biased rotating support ro mounted with the possibility of crocheting with the mounting table, with a front curtain located in the cutter blades and a spring-loaded sator, the cutter is set to be able to turn on an opaque guide fixed on the lid of an opaque guide made in the form of a tricky rolling pin with a face all over. The retainer is made in the form of a pin placed in the cutter body between conductive and safety curtain thirty 35 45 Emulative coil. The lid is opened by the mono-contacting table and the cutter 9 is moved to the working position. For this, the cutter 9 is rotated around the guide 10 until the contact ends with the flat of the guide and the other with a hole made in the front blind. 0 0 five 0 Therewith, the latch 21 under the action of the spring 23 emerges from the opening 20 of the shutter 15 and rests on the track 11 of the guide 10. To cut the photographic material, the operator presses the cutter 9 until the roller 24 contacts the surface of the assembly table 7 (or with the photo material 5) and moves it along the guide 10. When pressing the cutter 9, its body 13 with the blade 14, overcoming the force of the spring 17, will move downward relative to the shutter 15 and the blade 14 will go into the groove 8. When finished, press the cutter 9 spring 17 will turn the shutter 15 until it stops and the upper edge of the groove 18 to the stop 19, and the lower edge of the shutter lower below the cutting edge of the blade 14. To move the cutter 9 to its original position, rotate it around the guide 10. The retainer 21 will move from the flattening 11 to the cylindrical surface of the guide 10 and, squeezing the spring 23, will enter the hole 20 of the shutter 15, fixing its position relative to the housing 13. The proposed device, in addition to cutting, allows the camera to produce a photo material with subsequent rewinding, with the placement of the cutter on the lid of the opaque chamber and the presence of a protective latching shutter, which improves the operating conditions, which increase the ease of handling the device and prevent cuts to the operator when working in a darkened room.
