Patent ID: 7717039

Claim:
A rotating body of a printing press comprising: a rotating body barrel of said printing press rotating body, said barrel including a base body having a base body axial length; an outer body of said printing press rotating body, said outer body being positioned radially outside of, and spaced from said base body, said outer body having an outer body axial length at least equal to said base body axial length; an outer, closed cylindrical surface on said base body; an inner surface on said outer body, said inner surface on said outer body being spaced from said outer closed cylindrical surface on said base body and cooperating with said outer closed cylindrical surface on said base body to define a fluid impermeable annular space; a plurality of sleeves, each of a thermal insulating material supported on said base body, said plurality of sleeves each having a sleeve axial length less than said base body axial length, said plurality of sleeves being axially abutting and being enclosed in said annular space, each said sleeve having a sleeve inner surface in contact with said outer surface of said base body and having a sleeve outer surface in contact with said inner surface of said outer body, said plurality of axially abutting sleeves having a combined sleeve axial length not greater than said base body axial length; a plurality of axially extending, circumferentially spaced temperature control medium flow channels in each said sleeve, each said channel being formed in said outer surface of its one of said plurality of sleeves of said thermal insulating material, each said channel being thermally insulated from said base body by said thermal insulating material, said axially extending, circumferentially spaced channels in said axially abutting ones of said plurality of sleeves being aligned to each other to form continuous ones of said plurality of axially extending temperature control medium flow channels; and at least one fluid inflow for a temperature control medium at a first end of said base body and at least one fluid outflow for said temperature control medium at a second end of said base body, each of said plurality of temperature flow channels in said sleeves receiving said temperature control medium from said fluid inflow and providing axial flow of said temperature control medium through each of said continuous ones of said plurality of axially extending temperature control medium flow channels to said at least one fluid outflow to exchange an amount of heat between said outer body of said rotating barrel and said temperature control medium over each said continuous channel in said abutting ones of said plurality of sleeves during flow of said temperature control medium through each said continuous channel from said fluid inflow to said fluid outflow, while being thermally insulated from said base body.
