Method and apparatus for processing and transporting sheet materials

Claim 2

Apparatus for transporting and processing a sheet material with flowable process substance comprising: a source of flowable process substance; at least one 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 effective volumes of 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; means delivering a controlled volume of said flowable process substance to said web, said volume being sufficient to substantially fill said interstices; and means moving said sheet material and said web into surface-to-surface contact with and relative to one another with said protrusions in contact with 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.

Claim 3

The apparatus of claim 1, wherein said web comprises a woven screen.

Claim 4

The apparatus of claim 2 wherein said woven screen has a mesh opening between 25 percent and 75 percent of said web.

Claim 5

The apparatus of claim 1 wherein said web comprises individual filaments.

Claim 6

The apparatus of claim 1 wherein said web is essentially nonabsorptive of said process substance.

Claim 7

The apparatus of claim 1 and including a second pliable web having a multiplicity of protrusions defined on at least one surface thereof and being disposed in overlying relationship to the first web with said protrusions of said web being in contact and in fluid communication with said first web.

Claim 8

The apparatus of claim 1 and including a pliable cover disposed in overlying and covering relationship to said pliable web to minimize contact of said process substance with the atmosphere.

Claim 9

The apparatus of claim 7 and including means anchoring respective edges of said sheet material and said web so that a major portion of said sheet material and said web extend therefrom without further support by said mounting means.

Claim 10

The apparatus of claim 1, wherein said means transporting said sheet material comprises a moving belt.

Claim 11

The apparatus of claim 1, wherein said sheet material is a photosensitive sheet material.

Claim 12

The apparatus of claim 1 wherein said web is fixedly mounted and said sheet material is moved therepast.

Claim 13

The apparatus of claim 1 and including tube means connected to said source of flowable process substance, means securing one edge of said web in wrapping engagement with a portion of said tube means, and means providing fluid transfer between the interior of said tube means and said one edge of said web.

Claim 14

The apparatus of claim 1 wherein said web is of at least equal in width to the width of sheet material to be processed.

Claim 15

The apparatus of claim 1 including mounting means anchoring one edge of said pliable web so that a major portion thereof extends therefrom without further support by said mounting means.

Claim 16

Apparatus for processing a sheet material with a flowable process substance in which said sheet material is moved relative to a supply of said process substance comprising: a source of said flowable process substance; a mesh assembly receiving and distributing said process substance, including at least one 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 effective volumes of 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, mounting means anchoring only one edge of said pliable web with the remainder of said web extending from said mounting means, and means associated with said mounting means for dispensing said process substance to said anchored edge of said web; means delivering a controlled volume of said process substance to said mounting means, said volume being sufficient to substantially fill said interstices; and means transporting said sheet material in surface-to-surface contact with and relative to said web with said protrusions in contact with said sheet material whereby said sheet material is caused to contact said process substance disposed in 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.

Claim 17

Apparatus for processing a sheet material with a flowable process substance in which said sheet material is moved relative to a supply of said process substance comprising: a source of said flowable process substance; a mesh assembly receiving and distributing said process substance, including at least one 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 effective volumes of 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, mounting means anchoring only one edge of said pliable web with the remainder of said web extending from said mounting means, and means associated with said mounting means for dispensing said process substance to said anchored edge of said web; means delivering a controlled volume of said process substance to said mounting means, said volume being sufficient to substantially fill said interstices; and means transporting said sheet material in surface-to-surface contact with and relative to said web with said protrusions in contact with said sheet material whereby said sheet material is caused to contact said process substance disposed in 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.
