125 words
A wet treatment arrangement for photographic sheet carriers, comprising at least one liquid tank having an inlet slot and an outlet slot; and an upper side; at least one transporting roller located in said tank for transporting a sheet carrier from said inlet slot to said outlet slot; a cover part covering said upper side of said tank and provided with guiding surfaces for guiding a sheet carrier from said inlet slot to said transporting roller and from said transporting roller to said outlet slot, and also provided with transfer guiding surfaces, said first mentioned guiding surfaces and said transfer guiding surfaces merging with one another and being formed as guiding ribs extending transversely to a length of said rollers and parallel to one another.
Claim 2
Dependent Claim
125 words
A wet treatment arrangement for photographic sheet carriers, comprising at least one liquid tank having an inlet slot and an outlet slot; and an upper side; at least one transporting roller located in said tank for transporting a sheet carrier from said inlet slot to said outlet slot; a cover part covering said upper side of said tank and provided with guiding surfaces for guiding a sheet carrier from said inlet slot to said transporting roller and from said transporting roller to said outlet slot, and also provided with transfer guiding surfaces, said first mentioned guiding surfaces and said transfer guiding surfaces merging with one another and being formed as guiding ribs extending transversely to a length of said rollers and parallel to one another.
Claim 3
Dependent Claim
68 words
A wet treatment arrangement as defined in claim 1, wherein said guiding ribs of said cover parts located adjacent to one another are offset relative to one another with respect to the length of said rollers so that said ribs which form said transfer guiding surfaces in the neighboring cover parts engage with one another in form of a toothing with said cover parts placed on said tanks.
Claim 4
Dependent Claim
44 words
A wet treatment arrangement as defined in claim 1, wherein said guiding ribs have a shape which deviates from a curved shape of the moved sheet support so that only a front sheet support edge is considered in a movement direction runs along them.
Claim 5
Dependent Claim
34 words
A wet treatment arrangement as defined in claim 1, wherein said cover parts have ends which in direction of roller lengths extend outwardly beyond said guiding ribs and have inner surfaces provided with troughs.
Claim 6
Dependent Claim
35 words
A wet treatment arrangement as defined in claim 4, wherein said tank has tank walls which surround said rollers and are provided with projections formed so that said troughs can be placed on said projections.
