Problems solved by technology

However, it was pointed out that in such a device, if one wishes to add a device for automatically supplying the cassette parts and divide the device into units, the degree of freedom is small, so it is difficult to design the device in a flexible layout to meet the requirements of the device installation location requirements
Furthermore, the equipment is designed to be used in a fixed location in a given plant without the idea of ​​mobility being able to install the equipment in any location

Embodiment Construction

[0109] FIG. 1 is a perspective view of a film manufacturing apparatus 10 according to a first embodiment of the present invention. The film manufacturing equipment 10 is used to manufacture figure 2 The film loading cassette 12 is shown. like figure 2 As shown, an unexposed film web 14 carries a latent image as a side positive and has perforations 16 formed one after the other on opposite sides thereof and cutouts 18 formed at predetermined intervals on one longitudinal edge thereof, Each of the predetermined intervals is set to a given length according to the film size (film length), respectively. The film strip 14a unwound from the film roll 14 is cut to a prescribed length to form a cut-to-length film 20 which is then wound onto a spool 22 to form a roll assembly 24 . Afterwards, the roll film assembly 24 is inserted into the cassette 28 with one side open, the cover 26 is mounted on one end of the cassette, and the cover 30 is mounted on the other end of the cassette, t...

Abstract

A supply unit supplies a film strip from a film roll, and a winding unit cuts off a film strip into a fixed-length film and winds the fixed-length film around a spool to produce a wound-film assembly. An assembling unit introduces the wound-film assembly into a one-open-sided cartridge, and mounts and crimps a cap on the one-open-sided cartridge to produce a wound-film-loaded cartridge. After a pullout resistance of the film and a film length to be exposed are inspected, the wound-film-loaded cartridge is unloaded as a product.

Description

technical field [0001] The present invention relates to a film manufacturing apparatus and method in which cut-to-length film is wound on spools to produce a film assembly which is inserted into a cassette and a cover is fitted over the open end of the cassette to produce Out of the film loading cassette. Background technique [0002] In order to manufacture photographic photographic film contained in a cassette, the following sequential processes are generally required: the film strip is cut into cut-to-length films; the cut-to-length films are wound on spools to produce roll assemblies, which are inserted into In the cassette, install the cover over the open end of the cassette. So far, since these processes are completed by respective manufacturing facilities, when the semi-finished product is transferred between any two manufacturing facilities, it is necessary to provide a sufficient light-shielding environment, which requires a high cost to build a A facility that pr...
