PCT No. PCT/US83/00746 Sec. 371 Date Feb. 11, 1985 Sec. 102(e) Date Feb. 11, 1985 PCT Filed May 11, 1983 PCT Pub. No. WO84/04603 PCT Pub. Date Nov. 22, 1984.An automatic film threading apparatus (10) that allows roll-film (58) to be automatically threaded through a series of film developing and processing chambers (12a) located on a roll-film processor (50). The apparatus is further comprised of a powered film spool (52a) and a pinch roller (16a) disposed above the spool to form a rolling intersection. A spool and roller combination is located between the upper ports (12b) of each chamber pair. Also located above and below each chamber pair is an upper and a lower film guide (18) (56). Automatic threading is accomplished by extracting a small section of film (58) from its reel (14b) and attaching the film to one end of a threading leader assembly (15). The other end of the threading leader is then manually threaded through a first chamber pair where a threading tip (15c) engages the rolling intersection of the roller (16a) and spool (52a). From this point on, the film (58) is automatically threaded through each successive chamber (12a). |
