Definitions
- ABSTRACT This is a photographic processor having a plurality of pairs of cylindrical film transport rollers, the rollers in each pair being parallel to each other but adjacent pairs being respectively canted in opposite directions to produce a zigzag path for the marginal edge portions of the web being transported to limit the area of contact between said web and the rollers to the marginal edge portions of the web.

- S.M. 391,334 filed Aug. 24, 1973, now U.S. Pat. No.
- FIG. 1 is a fragmentary side elevational view showing a portion of a roller rack for a photographic processor embodying this invention (with the oscillating plate re moved);
- FIG. 2 is a horizontal sectional view taken substantially along the line 22 of FIG. 1 but showing a portion of the oscillating plate in operative position;
- FIG. 3 is a horizontal sectional view taken substantially along the line 3-3 of FIG. 1 also showing the oscillating plate;
- FIG. 4 is a fragmentary vertical sectional view taken substantially along the line 4-4 of FIG. 2;
- FIG. 5 is a fragmentary end elevational view showing three (3) pairs of typical rollers.
- FIG. 1 A portion of a roller rack for a photographic film processor which embodies this invention is best shown in FIG. 1.
- the rack illustrated includes a web transport mechanism which has a pair of parallel fixed side panels or mounting plates respectively designated by the numerals 14 and 15.
- This roller rack is removably mounted in conventional processing tanks (not shown) similar to those described in my previously identified co-pending application (Ser. No. 391,334) now U.S. Pat. No. 3,830,419.
- the present transport mechanism includes a plurality of pairs of cylindrical film transport rollers 16 with the rollers of each pair having parallel axes.
- Each roller 16 is fixed to a supporting shaft 17 which is mounted for rotation between the pair of mounting plates 14 and 15.
- the ends of adjacent pairs of rollers 16 are respectively offset in opposite directions to cant the axes thereof into oblique (out of normal) relation to the planes of the plates 14 and 15.
- the relationship is best shown in FIGS. 2 and 3 by the center lines 16a of the rollers 16 and the lines 20 which are disposed normal to the planes of the plates 14 and 15. This produces the desired zigzag path of the two marginal edge portions W-l of the web of photographic material W, thus limiting the area of contact with the rollers to said marginal edge portions.
- any suitable means for imparting rotary driving motion to the rollers 16 may be provided such as the DRIVING MECHANISM FOR ROLLER TRANSPORTING DEVICE disclosed in U.S. Pat. No. 3,608,807.
- This mechanism includes an oscillating plate 18, best shown in FIGS. 2, 3 and 5.
- One shaft 17 of each pair of rollers has a crank arm 18a fixed in radially outstanding relation thereto and these crank arms 18a are respectively engaged by crank pins 18!; fixed in outstanding relation to said oscillating plate and driven thereby in the manner set forth in said prior patent.
- the present mechanism includes only one such plate which is designed to drive only one of each pair of rollers.
- the other roller in each pair is driven by a pair of meshed gears 19 respectively fixed to the ends of the shafts 17 opposite to the ends to which the crank arms 1811 are fixed. This is best shown in FIGS. 2, 3 and 5.
- the rollers are oriented in such a manner as to define a continuous web path through the processing tanks (not shown) and the marginal edge portions W-l of the web follow a zigzag path as shown in FIG. 4.
- the opposed surfaces of the rollers 16 are spaced apart a distance greater than the thickness of the web W of material being transported and center portion W-2 of the web W is out of contact with the rollers as best shown in FIGS. 2 and 3.
- squeegee rollers (not shown) at the top of the exit portion of the web path aboveeach liquid confining tank.
- These squeegee rollers are in surface contact and are positioned above the liquid level of each of the liquid tanks. They are of soft yieldable material and are positioned to press against both sides of the web to squeegee off" substantially all of the liquid from the surface of the web W as it is transported out of each tank.
- a mechanism for transporting elongated webs of photographic sheet material through the processor comprising:
- roller supporting structure a. plurality of pairs of cylindrical transport rollers mounted on said structure and arranged to define a continuous web path through the processor, the spacing between the rollers of each nair being greater than the thickness of the web to be transported and the rollers of each pair being parallel to each other, adjacent rollers being oppositely canted to produce a zigzag path for the marginal edge portions of a web of material being transported through said roltherein.
- each roller extending therebetween and having the roller ends journaled for rotation on the respective plates, the canted relation of the rollers being produced by orienting the axes thereof in oblique relation to the planes of said mounting plates.
