Abstract

PURPOSE:To reduce a loss part of the circumference of a disk greatly by punching a film sheet in a zigzag punch pattern having >=2 lines. CONSTITUTION:Long-sized films which are wide enough for punching disks in >=2 lines are spliced by a splicing machine, and the spliced film is checked and confirmed by an inspecting device; and a center hole for the insertion of a core and a core ring 2 is perforated in the film and at the same time, positioning holes (f) and an outer circumferential notch hole 4 are perforated. Then, frame numbers and frames are printed by exposure, a bar code are printed around the center hole 3, and the core 1 and core ring 2 are connected to the center hole 3 by deposition. Thus, a disk film punched in a disk shape is obtained.

After passing through 3 processes, when the product is transported to the final processing stage 1, it is a high-strength product. 43, the force 11 yield is an important factor in determining the cost of the final product.That is, as shown in Figure 1, for example, several frames 5 of fr, 'l'- are arranged radially like 15 frames. death/
The same thing can be said in the case of a rotary inter-disk film (hereinafter referred to as a disk 7-f lum) that extends from the disc-shaped lume.

When the disc-shaped film is removed from the film sheet of Ilj every month, the surplus around the disc is 1EI.

Improvements were also required from the perspective of saving luxury on high value-added silver JJA Firno.

Not only from the perspective of saving silver resources, but also from the perspective of automating the production line and increasing the efficiency of loading and packaging the manufactured disk fill into the cartridge, it is necessary to use two or more rows of disk-shaped disks in the same way. It is preferable that the film be shot in parallel, but in general parallel printing,
There is a significant loss of excess joints around the disc, and there is a % wastage of silver resources.

J Santo-Jru 447 disc film.

Hereinafter, the manufacturing method of the disc film for copying according to the invention will be explained in detail with reference to FIGS. 3 and 4.

In order to perform circular mt-shaped punching of the disk film from the filter sheet, parallel punching (Fig. 3) or staggered arrangement (Fig. 4) is usually considered.

In Figure 3, the square portion shown as AI represents one pair of ice shoes. In the film area required for 4J, the shaded area of A2 indicates the loss.

Disc 7-(If the diameter of the lum is 1 μm fD, in the parallel punching pattern, as shown in Fig. 4, in the staggered rJ punching pattern, the angle 6 is t).
Since the rows are arranged with a circle n; at an inclination of 0°, A1 is (匡〉(3)) and A2 is (2Df4), so the staggered batting pattern is more accurate than the L. Since the area required for film and loss (11t) per shim are small, high-yield production can be expected.

8I: The common thread ladle has the disadvantage that the extra joints after punching are troublesome, which increases the product cost of the disc film, and there is no ft-saving source, that is, no silver effect. On the other hand, compared to the parallel punching method, the staggered punching method of the present invention can achieve 11"1" state distribution and reduce the product cost of disk 7 and r lume by 8"1". In addition, if a wide long film is fed at a constant speed and the position 1 is precisely controlled, the A for the adjacent disk shape can be It prevents thick contact and prevents the irregularly shaped disc from having 4" J Buddha < AJT.

゛Also, when deciding on the 1'J extraction pattern, use r month entry sheath fJ)l, feed 4'iIU, and C cap.
In feeding the 19th web after cutting, the J'J cutting interval of the Te-1 film was left slightly different, and the web of only IEI fabric was cut with the tensile strength of the winding υ. I won't wake up 1; I'm going to choose IA', l); I'm in good shape.

Since all configurations with K-base 5 and positioning can be adopted, the occurrence of defective products of TE/F Scuffino I11 is extremely small, and with the bracket movement control 1 and 3L''-), process pipe use can be performed. Therefore, it is possible to effectively reduce the product cost of disc film.
