Definitions

  • the mechanism includes a plurality of pairs of oppositely tapered rollers having opposed surfaces spaced apart a distance slightly greater than the thickness of the web to be transported, the rollers of adjacent pairs being oppositely tapered and arranged to alternately offset the marginal edge portions of the web path defined thereby and produce a zigzag, twisting action on the web to cause the frictional driving pressure to be exerted only on the marginal edge portions of said web and also permit a spacing wider than the web thickness be maintained between each pair of rollers.
  • FIG. 1 is a side elevational view of the transport mechanism with the oscillating plate removed;
  • FIG. 2 is an end elevation of the transport mechanism taken substantially along the line 22 of FIG. 1;
  • FIG. 3 is a fragmentary horizontal sectional view taken substantially along the line 3-3 of FIG. 2;
  • FIG. 4 is a fragmentary vertical sectional view taken substantially along the line 4-4 of FIG. 2.
  • the photographic processor which embodies this invention is best shown in FIG. 1 and includes an outer housing or casing designated by the letter C.
  • the particular processor illustrated includes four separate processing tanks respectively designated by the numerals 10, 11, 12 and 13.
  • Tanks 10, 11 and 12 each contain a different liquid used in the processing system and tank 13 defines a drying chamber.
  • the transport mechansim includes a pair of side panels or plates respectively designated by the numerals I4 and 15.
  • the transport mechanism includes a plurality of pairs of tapered rollers 16. Each roller is mounted for rotation between the plates 14 and 15 on suitable supporting shafts 17 respectively rotating on axes 17a.
  • any suitable means for imparting rotary driving motion to the rollers 17 may be provided such as the DRIVING MECHANISM FOR A ROLLER TRANS- PORTING DEVICE disclosed in my U.S. Pat. No. 3,608,807.
  • This mechanism includes a single oscillating plate (not shown herein) to which a plurality of driving pins 18b are fixed.
  • 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 the crank pins 18b which in turn are driven by said oscillating plate in the manner set forth in said prior patent.
  • the present mechanism includes only one such plate which is designed to drive only one ofeach 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 l7 opposite to the ends to which the crank arms l8a'are fixed. This is best shown in FIGS. 2 and 3.
  • the axes of adjacent pairs of rollers are oriented in such a manner to define a continuous web path through the processing tanks 10, ll, 12 and 13.
  • a plurality of rollers 16 are provided which are tapered from one end to the other and the opposed surfaces thereof are spaced apart a distance greater than the thickness of a web W of material to be transported.
  • the direction of taper of one roller in each pair is opposite to the direction of taper of the other roller in that pair as best shown in FIG. 3.
  • the direction of taper of each pair of rollers is opposite to the direction of taper of adjacent pairs of rollers.
  • the web of photographic material W is best shown in FIGS. 3 and 4 which illustrate the zigzag path followed by the marginal edge portions of the web W through the roller train and the photographic processing tanks.
  • squeegee rollers 20 are in surface contact and are positioned above the liquid level of each of the liquid tanks, 10, 11 and 12. 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 transport mechanism for elongated webs of sheet material comprising a roller supporting structure
  • each roller being opposite to its adjacent rollers and said rollers being oriented to produce a zigzag path for the marginal edge portions of a web of material being transported through said rollers
