Definitions

  • Processing is achieved at the processing station by a member movable from a normal retracted position, in which it is out of engagement with the film and web, to a laminating position, in which it moves portions of the film and web into intimate pressure engagement for a predetermined time interval.
  • the web and film are separated upon return of the member to its normal retracted position by the combined action of the tension on the web and the angles of approach and separation defined by the film and web when they are in pressure engagement.
  • An auxiliary separator member may be provided movable between the film and web and across the processing station to separate the film and web.
  • This invention relates generally to photographic processing apparatus, and more specifically to a processing device of the type in which a web containing a processing solution such as a developer is brought into and out of intimate pressure engagement with an exposed film for processing it.
  • This invention includes within its scope a web processing device of the type in which a web containing a processing ingredient or solution such as a developer is moved into and out of intimate and preferably pressure engagement with an exposed film for processing it.
  • the processing device is provided with a processing station, and means for transporting and guiding the film and web through the processing station along normal paths which are maintained in spaced relation to one another, and onto suitable takeup reels.
  • the processing device is further provided with laminating means at the processing station movable from a normal retracted or delarninated position to a processing or laminated position for moving the film and web into intimate pressure engagement for movement in a laminated condition at the same speed for a predetermined time to effect processing.
  • One of the objects of the present invention is to provide a web processing device of the type in which a film and web are brought into intimate pressure engagement for processing, and then immediately separated after the processing operation is completed.
  • Another object of the invention is to provide a web processing device of the type in which a film and web are moved into intimate pressure engagement for processing, in which the film and web are automatically separated following the processing operation by virtue of the tension on the film and web and the angles of approach and separation defined by the film and web at their contact lines where the two are initially brought into engagement and then separated.

  • the shaft 40 and lever 38 are rotated initially in a clockwise direction as seen by the arrow in FIG. 1 from its normal position to an operative position to effect processing as seen in FIG. 2, and then back to its normal position as seen in FIG. 3 to affect delamination of the film l6 and web 28 and to complete a processing cycle.
  • the rotation of shaft 40 and lever 38 is achieved by anysuitable mechanism, such as a motor 45 shown dotted in FIG. I drivingly connected to shaft 40 through any suitable clutch, not shown.
  • movement of lever 38 and rollers 44 in a clockwise direction (see arrow in FIG. I) to the operative position causes the rollers 44 to engage the outer or back surfaces of the film l6 and web 28 and to urge them together into intimate pressure engagement as seen in FIG. 2.
  • this processing or lamination mode In this processing or lamination mode,
  • rollers 44 urges the web 28 and film 16 into pressure engagement with a backup roller 46 rotatably mounted on a fixed shaft 48.
  • a backup roller 46 rotatably mounted on a fixed shaft 48.
  • the processor 8 When the processor 8 is initially turned on the web takeup spindle 30 is driven by any suitable pacer motor 50 as seen dotted in FIG. 1 for winding the web 28 on the takeup spool 32.
  • Another motor 52 drives the film takeup spindle 18 through any suitable friction clutch, not shown, for winding up the film as it is being processed.
  • the laminating rollers 44 are moved into the laminating mode by motor 45 and the film 16 and web 28 are transported together onto their respective takeup spools 20, 32.
  • the extend to which the film 16 is processed is determined by several factors, such as, the transport speed of the film and web, the temperature of the film and web, and the distance over which the film and web are laminated.
  • delamination is achieved by disabling motors 50, 52 and enabling drive motor 45 for the laminating mechanism 36 causing the lever 38 and rollers 44 to return to their initial normal position as seen in FIG. 3.
  • the film l6 and web 28 are unsupported in the processing station and automatically begin to separate due to the combined action of forces and tension to which the film 16 and web 28 are subjected by motors 50, 52 during the processing operation, and the angles of approach and separation, A and B respectively, as seen in FIG. 2, defined by the film l6 and web 28 at their contact lines C and D where the two are initially brought into engagement and then separated respectively as seen in FIG. 2.
  • an auxiliary separator comprising one or more rollers 54 interposed between the film 16 and web 28 and mounted byany suitable means for reciprocal movement through the processing station 10 between normal position E and position F as best seen in FIG. 4 for positively assuring separation of the film l6 and web 28.
  • the separation rollers 54 are returned to their initial position E and the processing device 8 is once again in its standby mode.
  • the processed film 16 may now be moved back and forth between reel 14 and spool 20 to permit reading out or viewing of any portion of the processed film. This action may be accomplished by sequentially disabling motor 52 and enabling a motor 56 coupled to spindle 12 for rewinding film 16, and then disabling motor 56 and enabling motor 52 to wind the film on spool 20.
