Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
166 words
In a plant for surface treating, in particular pickling and phosphatizing metallic work pieces having a plurality of treatment chambers arranged one behind the other, tightly connected to one another and provided with internal equipment, such as working tools, supporting elements and conveying rollers for transportation of the work pieces within the treatment chambers, the improvement wherein there are at least three chambers, each chamber having releasable connecting means at both ends for releasable connection to adjoining chambers, said connecting means of all chambers being substantially identical and all chambers being of equal length so that all chambers are interchangeable with one another, and means for individual displacement of each of the treatment chambers transversely of the direction of transportation of the work pieces to enable at least part of the internal equipment of a chamber to be removed from the chamber in a longitudinal direction parallel to the direction of transportation of the work pieces, and to enable the chambers to be replaced or interchanged.
Claim 2
Dependent Claim
166 words
In a plant for surface treating, in particular pickling and phosphatizing metallic work pieces having a plurality of treatment chambers arranged one behind the other, tightly connected to one another and provided with internal equipment, such as working tools, supporting elements and conveying rollers for transportation of the work pieces within the treatment chambers, the improvement wherein there are at least three chambers, each chamber having releasable connecting means at both ends for releasable connection to adjoining chambers, said connecting means of all chambers being substantially identical and all chambers being of equal length so that all chambers are interchangeable with one another, and means for individual displacement of each of the treatment chambers transversely of the direction of transportation of the work pieces to enable at least part of the internal equipment of a chamber to be removed from the chamber in a longitudinal direction parallel to the direction of transportation of the work pieces, and to enable the chambers to be replaced or interchanged.
Claim 3
Dependent Claim
24 words
A plant as set forth in claim 1, wherein the working tools are selectively designed as spraying nozzle units, jet units and brushing elements.
Claim 4
Dependent Claim
27 words
A plant as set forth in claim 1, wherein said chambers comprise first treatment chambers equipped with spraying nozzles and second treatment chambers equipped with brushing elements.
Claim 5
Dependent Claim

A plant as set forth in claim 1, wherein the means for moving the treatment chambers transversely to the direction of transportation of the work pieces include rollers by which the treatment chambers are displaceable.
Claim 6
Dependent Claim
41 words
A plant as set forth in claim 1, wherein the means for moving the treatment chambers transversely to the direction of transportation of the work pieces comprises a pivotal mounting whose axis of rotation is parallel to the direction of transportation.
Claim 7
Dependent Claim
80 words
A plant as set forth in claim 1 for pickling or phosphatizing metallic work pieces, wherein the internal equipment of at least one of the treatment chambers comprises a supporting track construction arranged in a treatment chamber, a frame-shaped inset slidably supported on said supporting track construction, supporting brackets secured to the frame-shaped inset, conveying rollers supported in the supporting brackets, and a tube coil provided with spraying nozzles for supplying a treating medium and supported by the frame-shaped inset.
Claim 8
Dependent Claim
34 words
A plant as set forth in claim 6, wherein there are a plurality of said coils in said chamber, said coils each being of helical configuration and being longitudinally overlapping relative to one another.
Claim 9
Dependent Claim
48 words
A plant as set forth in claim 1, wherein the internal equipment of at least one of the treatment chambers comprises a supporting track construction arranged in the treatment chamber, a frame-shaped inset slidably supported on the supporting track construction, and brushes rotatably mounted on the frame-shaped inset.
Claim 10
Dependent Claim
51 words
A plant as set forth in claim 1, wherein part of the treatment chambers is provided with driven conveying rollers having shafts penetrating the treatment chambers and wherein the remaining internal equipment of the treatment chambers is detachable from the conveying rollers and removable from the treatment chambers in longitudinal direction.
Claim 11
Dependent Claim
20 words
