Claims
- 1. Apparatus for transporting and processing a sheet material with a flowable process substance on opposite sides of said sheet material simultaneously comprising:
- at least one source of flowable process substance;
- a first pliable web having a multiplicity of protrusions defined on at least one surface thereof, said protrusions being spaced apart from one another in a substantially uniform distribution over said one surface and defining interstices therebetween for receiving said flowable process substance therein, said interstices being in fluid communication with adjacent interstices thereby defining fluid communication channels over substantially the entire area of said surface;
- a second pliable web having a multiplicity of protrusions defined on at least one surface thereof, said protrusions being spaced apart from one another in a substantially uniform distribution over said one surface and defining interstices therebetween for receiving said flowable process substance therein, said interstices being in fluid communication with adjacent interstices thereby defining fluid communication channels over substantially the entire area of said surface, said webs being disposed in surface-to-surface relationship with their respective protrusions facing each other to define a path therebetween along which said sheet material can move;
- means delivering a controlled volume of said flowable process substance to each of said webs, said volume being sufficient to substantially fill said interstices of each web; and
- means transporting said sheet material in surface-to-surface contact with, relative to, and between said webs with said protrusions of said webs in contact with opposite surfaces of said sheet material whereby said sheet material is caused to contact said process substance disposed in said interstices and said process substance is caused to flow within and between said interstices and said process substance in said reservoirs is agitated thereby transferring process substance which has contacted said sheet material away from said sheet material and causing such process substance to be mixed with other process substance in said reservoirs.
- 2. The apparatus of claim 1 and including a further source of flowable process substances, and further means delivering a controlled volume of said further flowable process substance to one of said webs.
- 3. The apparatus of claim 1, wherein said sheet material is a photosensitive sheet material.
