The innovation relates to a film tape with at least one Pilmbildstrelfen _s at least one perforation and at least one Tonpisteο

In medium-sized and smaller cinemas, filming " Iranians encounter greater personnel difficulties". In the absence of suitable skilled workers, insufficiently trained staff is often employed _, which often leads to disruptions in the performance and generally leads to a poor performance

For other reasons one has recently been striving for one

matisation of the film showing is now _B that a

can be accommodated "Considering _s that with a 35 mm copy a soiehes Ppograism kg a length of approx»% 00Ö m and a weight of about ^ O has ,, so illuminated readily ELN _s that for accommodating the assumed Pro = grammes awf of a single reel required reduction in weight wna des ümfaüges of the copy (up to about 8 kg

or = 2000 m with the same playing time) only by a © Fingerling the film bandwidth and thus the image size can be achieved"

but now immediately the question of the adequate picture «= and sound reproduction.

What tung image reproduction ,, ie, the brilliant Ausleueh = · a sufficiently large screen area _{s s} terms so are gwar with xenon lamps light sources for high-intensity projections% uw available. However, the light intensity of a 900 ¥ Lamp © with the small picture ^ ma.n already no window size of 16 mm cine film more fully awsßütEen _o The enlargement of a film image 7 _seconds l6 se 9sβ mm (picture windows of 16 mm Sehmalfilmes) - to the screen format a modern large cinema therefore proves to be inadequate even with the best optics (in the absence of a sufficiently brilliant illumination of the screen surface).

The difficulties with regard to sound reproduction ₉ are similar if one skips over two 16 mm cine films from 35 mm film in order to reduce the weight and size of the film copy? With regard to the reduction in the secondary cycle length caused by the reduction of the film image, the upper frequency of the optical tone is, for example, the magnetic tone, and

-Playback so much reduced ₉ that the sound reproduction is perceived as insufficient by the visitor

In summary, it can be stated that the

Film screening are appropriated while other high hoehwertiger picture and sound _s namely the 35 ram format especially its weight and Yoiumens Yiegen "ad the ram 16 formst the insufficient quality of image" and sound for _β

The innovation is therefore the task of smg2? Tind @ ₉ @ia Pilmband to create _s that see for @ a vollautoamtlseh

For the solution in accordance with the innovation, it is above all essential ₉

that the width of Perforafeionslöcher compared to the known film strips (having their holes at 35 asa film has a width of 2 ^ 8 RTMI) significantly reduced Is ₉ "preferential = 'as _s mm to a value of about I ₃ ¹ S of for proper film transport sufficient <,

An appropriate arrangement of the hiring sees that »starting from one edge of the film tape - side by side.

The innovations are based on the following description © Iniger In the drawing a demonstration of the design

The Pig »! through 9 show various exemplary embodiments of the filia ribbon _{β according to the invention}

The film tape i shown in Pigoi contains, starting from the left edge of the tape, a light and / or magnetic sound track 2 _S next to one another, a perforation formed by rectangular holes 3 and a perforation extending from this

The Tompiste 2 has a sufficient width for optical sound or magnetic = sound recording between 0 _s 5 and ^ J mnu

an area of

If one proceeds from these preferred data (width © of the area used to record the sound track 2 _S 5 sram and Perforationslochbreit® I ₈ H Ma) _{5 the} following examples clearly show the new enlargement of the film images

Example I;

A 16 on the conventional type of narrow film has a film · = image in the size of 9 _S 6 χ 7.1 mm. The film image

2
area is thus about 69 mm <> To see bsi can use a particular light source a good Lein "mural in OCE size of about 3 χ H m project _β

A new feature according to 16 mm cine film, the space sur receiving a Lichttonpiste has _s has other hand, a film image of 12 _s i χ 7 _s l6 mm with an area van about 87 mm "It can be using the same light source is a substantially greater _s gist Project an illuminated canvas image as with the well-known 1β mm narrow film.

To dispense with a Lielittonwiedergafoe _s one sees so sufficient for a magnetic sound narrower margin rait a width of about 6 mm Ο ,, so the scene can be further

Example Ils

A 35 mm normal film has a film image of 15 ₉ 2 χ

P 2O ₃ 9 mm with an area of about 318 ram _e

In the case of a 35 ram film according to the invention and the selection of an edge area of 2 ₉ 5 mm wide and one for the recording of the sound track

In contrast, a perforation hole width of l _{s k wm is obtained}

a film image of 19 χ 31.1 mm with an area of 590. This means that when the same light source is used, a much larger image area on the screen can be illuminated than with normal film.

Pig. 2 shows an output limb and with a width of 35 For the production of three pilra strips according to Figol with one width of 17s5 each

The dimensions are expediently chosen as follows: "Yam edge to su the perforation holes 2 _S 5 perforation hole width l _s ^ 5 im _s perforation hole height 1 _S 98 center distance of the perforation holes 4 ₃ 75

The two film tapes produced by cutting along the line 8 with a _{width of 17 S} 5 mh then have a film image =

finer of 9 _a 5 x 13 ₉ 6 mm (area 129 mm ² ) _s which result in brilliant illumination of the usual projection walls with the light sources available today. = The area of a film image field is almost twice as large as in the Ira example I. explained known 16 mm
