A rapid access processing method for processing and delivering successive image frames on a continuous carrier web in a manner so that processing liquid spread over the area of each image frame on the carrier web is confined essentially to the image frame to leave areas of the carrier web uncovered by the image frame free of processing liquid. The carrier web also supports a pod of processing liquid along a leading edge of each image frame as well as a trap along a trailing edge of each image frame. The spent pods and wet traps are transferred from the carrier web, after processing, to an image bearing web from which image media was transferred to the image frames during processing. |

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT As shown in FIG.
1 of the drawings, an image-receiving web assembly adapted for use in the practice of the present invention is generally designated by the reference numeral 10.
In the illustrated embodiment, the web assembly 10 includes a continuous carrier web 12 supporting on one surface thereof a plurality of longitudinally spaced image-receiving sheets 14, each having leading and trailing edges 16 and 18, respectively, and parallel opposite side edges 20.
Positioned on the carrier web 12 near the leading edge 16 of each image-receiving sheet 14 is a rupturable processing liquid pod 22.
Near the trailing edge 18 of each image-receiving sheet 14 is a generally rectangular processing liquid trap 24.
In the embodiment of the web assembly 10 shown in FIG.
1, each of the image-receiving sheets 14, pods 22 and traps 24 is releasably secured to the web 12 by adhesive compositions having selected adhesion strengths and to be described in more detail below.
As may be seen in FIG.
1, however, the regions of such adhesive securement are delineated by cross-hatching and extend as narrow transverse stripes along the leading edges of the respective components secured to the web 12.
Thus, each of the image-receiving sheets 14 is secured by a stripe 26 of adhesive along the leading edge 16 thereof.
In similar fashion, the pods 22 and traps 24 are secured to the web 12 by stripes of adhesive 28 and 30 along the respective leading edges of these components.
Also, the top surface of the pod 22 in the illustrated embodiment is provided with a pressure sensitive adhesive coating depicted by stippling in FIG.
1 of the drawings.
A more complete understanding of the characteristics of the web assembly 10 will be had by reference to FIG.
2 of the drawings in which the processing operation of the invention is generally illustrated.
As shown in FIG.
2, a rolled supply of the web assembly 10 is fed through successive linear runs defined respectively by an idler roller 32 and a processing roller pair 34, on the one hand, and by the roller pair 34 and another idler roller 36 located on the opposite side of the processor roller 34 from the idler 32, on the other hand
