Description

ss1oz6s2-6 I 2. ss1oz6s2-6 I 2.

Konstruktionen gäller för alla kända nu tillverkade fotogra- ' fiska_filmer, negativa, positiva, svart-vita och färgfilmer.The design applies to all known now-produced photographs. fiska_filmer, negative, positive, black and white and color films.

Rören-som är av lämplig dimension för varje filmbredd, samt försett med ett uppslitsat spår är av ett mot de i processen ingående kemikalierna resistent material, t ex plast eller syrafast material. j f - Rören formas till en spiral med lämplig längd och diameter ~för varje del av processen (detalj l i figur 1 - 4) samt ned- .färdig_och torr enligt filmfabrikantens anvisningar. sänkes i en för- varje process separat tankdel i en gemensam tank, så att filmen därvid kommer att röra sig ”ändlöstf genom I processen, dvs utan avbrott, och slutligen kommer fram helt Filmen föres medelst en i filmens början fäst ledare (detalj 3 i fig 2) geno ett i röret anbringat spår med mekanisk _, medbringare (detalj nr 4 i fig 2i- 4). j ' jnedbringaren (detalj 4 i fig 2-4) kan bestå av en eller flera armar, är fäst på en roterande axel och följer insidan av rör-_ slingan och för därvid ledaren (detalj 3 i fig 2) och filmen genom slingan. För varje separat tankdel finns en MEDBRINGARE som synkront följer rörelsen. MEDBRINGARENS (detalj 4 i figur *2'- 4) hastighet måste därvid anpassas till spiralens längd och processtiden.The tubes- which are of suitable dimension for each film width, as well provided with a slit track is of one against those in the process constituent chemicals resistant material, eg plastic or acid-resistant material. j f - The tubes are formed into a spiral of suitable length and diameter ~ for each part of the process (detail 1 in Figure 1 - 4) and .finished_and dry according to the film manufacturer's instructions. is lowered in one for each process a separate tank part in a common tank, so that the film will thereby move "endlessly through I the process, ie without interruption, and finally emerges completely The film is conducted by means of a conductor attached to the beginning of the film (detail 3 in Fig. 2) through a groove arranged in the pipe with mechanical _, carrier (detail no. 4 in Figs. 2-4). j The reducer (detail 4 in Figs. 2-4) may consist of one or more arms, is attached to a rotating shaft and follows the inside of the tube-_ the loop and thereby the conductor (detail 3 in Fig. 2) and the film through the loop. For each separate tank part there is a CARRIER which synchronously follows the movement. CARRIER (detail 4 in figure * 2'- 4) speed must then be adapted to the length of the spiral and process time.

Vid övergång till varje separat del hindras västskeöverfö- ring medelst avrinning genom spåret och anbringat hål, samt , en tidigare känd metod att hindra vätskeöverföring vid rör- - slingans skarv (detalj 2 figur l)._When transferring to each separate part, the bag transfer is prevented ring by draining through the groove and fitted holes, and , a prior art method of preventing liquid transfer at pipe - loop joint (detail 2 figure l) ._

Claims

8103662-6 3. P A T E N T K R A V

A photographic film developing apparatus in which, during the developing process, the film is transported between containers containing process chemicals by a mechanical transport device, characterized in that the transport device comprises a cylindrical, helical tube loop (1), in which the inner diameter of the tube is adapted to the width of the film and the length of the tube is adapted to the process time, a film conductor (3) movable through the tube of the tube loop, to which one end of the film is attached during the process and a rotatable shaft about the helical tube loop. carrier (4), which acts on the film conductor (3) with a force intended for its propulsion and which is rotated in operation by a suitable drive device.

Device according to Claim 1, characterized in that the pipe loop (1) is provided with a slot-shaped groove.

Device according to claims 1 or 2, characterized in that the film guide (3) is provided with a projecting part intended to be brought into contact with the carrier. ~

Device according to claims 1 - 3, characterized in that the carrier is provided with at least one straight elongate part parallel to the axis of rotation, which is arranged to be brought into contact with the projecting part of the film guide (3).
