Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
174 words
A method of applying a given amount of white paint by rolls to all the outer surface of a cylindrical can body which is transported along a passageway as it is supported by a supporting element extending in a direction perpendicular to said passageway, wherein all the said outer surface of the cylindrical can body is brought into contact with a first rotating application roll being close to said passageway and carrying white paint, thereby transferring the white paint in a part of said given amount from said first application roll onto said outer surface of the can body to coat said surface, said coated outer surface of the can body then being brought into contact with a second rotating application roll carrying white paint, being close to said passageway and positioned downstream of the first application roll in the advancing direction of the can, thereby transferring the white paint in the rest of said given amount from said second application roll onto the coated outer surface of the can to coat said surface.
Claim 2
Independent Claim
174 words
A method of applying a given amount of white paint by rolls to all the outer surface of a cylindrical can body which is transported along a passageway as it is supported by a supporting element extending in a direction perpendicular to said passageway, wherein all the said outer surface of the cylindrical can body is brought into contact with a first rotating application roll being close to said passageway and carrying white paint, thereby transferring the white paint in a part of said given amount from said first application roll onto said outer surface of the can body to coat said surface, said coated outer surface of the can body then being brought into contact with a second rotating application roll carrying white paint, being close to said passageway and positioned downstream of the first application roll in the advancing direction of the can, thereby transferring the white paint in the rest of said given amount from said second application roll onto the coated outer surface of the can to coat said surface.
Claim 3
Dependent Claim
15 words
A method as claimed in claim 1 in which said passageway is vertical and circular.
