Abstract
Abstract In a process and apparatus for use in surface treating cylindrical bodies, in particular for performing a painting operation thereon, the process provides for the translation of the cylindrical bodies whereby said bodies are supplied to, and discharged from, a rolling device associated with a painting booth, and the cylindrical bodies are driven in rotation and kept rotating with respect to their axis that is disposed in a vertical direction. The apparatus for carrying out the process comprises a series of rotary and conveying members which are designed to engage the vertically disposed cylindrical bodies at their lower base with reduced contacting areas therebetween, and to drive said bodies in rotation, the conveying members being in turn designed to keep the cylindrical bodies rotating during their translation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
69 words
A process and apparatus for the surface treatment of cylindrical bodies, in particular for spray painting both the internal and external surfaces thereof, wherein the process provides for the translation of the cylindrical bodies so as to have them supplied to, and discharged from, a rolling device associated with a painting booth, said cylindrical bodies being driven in rotation and kept rotating with respect to their vertically directed axis.
Claim 2
Dependent Claim
69 words
A process and apparatus for the surface treatment of cylindrical bodies, in particular for spray painting both the internal and external surfaces thereof, wherein the process provides for the translation of the cylindrical bodies so as to have them supplied to, and discharged from, a rolling device associated with a painting booth, said cylindrical bodies being driven in rotation and kept rotating with respect to their vertically directed axis.
Claim 3
Dependent Claim
85 words
The process according to claim 1', wherein the process, which is carried out in a plurality of sequentially operating stations, comprises the steps of: removing the cylindrical bodies from a line of production, driving the cylindrical bodies in rotation about their vertical axis with an adjustable speed, subjecting the cylihdrical bodies to a process operation, in particular to a spray painting operation, while said bodies are rotating about their vertical axis, slowing-down and braking the processed bodies, and discharging them to a line of production.
Claim 4
Dependent Claim
45 words
The process according to claims 1 and 2, wherein translation of the cylindrical bodies from each station to the next one, r is carried out while said bodies are kept rotating with respect to their own axis, said axis being disposed in a vertical direction.
Claim 5
Independent Claim
69 words
An apparatus for carrying out the process according to claims 1 to 3, wherein the apparatus comprises a series of rotating and conveying members which are designed to engage the vertioal- ly disposed cylindrical bodies at their lower base with reduced contacting areas or nip therebetween, and to drive the bodies in rotation, the conveying members being in turn designed to keep the cylindrical bodies rotating during translation thereof.
Claim 6
Dependent Claim
58 words
The apparatus of claim 4, wherein supporting units are provided and each of these supporting units consists of a set of three rolls, said rolls being each in the form of a truncated cone having an enlarged base in order to provide an abutment surface for the lower face of a barrel,with vertically directed axis,to bear there against.
Claim 7
Dependent Claim
40 words
The apparatus according to claim 5, wherein the support rolls in the stations in which the cylindrical bodies are driven in rotation and subjected to process operation, are powered rolls, while the rolls in the braking station are idle rolls.
Claim 8
Dependent Claim
63 words
The apparatus according to claim 4, wherein translation units are provided and each translation unit consists of a set of three rotary rolls that are disposed with vertically directed axis, these rolls being angularly offset - as seen in a plan view - with respect to the rolls of the supporting units, and being movable in both a vertical and an horizontal direction.
