Abstract
Abstract Sharp, endless sleeves for rotary screen printing having superior durability to printing can be obtained by a method of the present invention. According to this method, a metal image-forming layer having a smooth endless outside surface and a thickness in the range of 5-50μ is made, and into the inside thereof is inserted a cylindrical screen sleeve as an image-supporter made of a metal or a non-metallic material having been processed to provide electric conductivity thereto, and both the layers and the sleeve are fixed to each other with electro- or chemical- plating, or on the outside of a cylindrical screen sleeve, is formed a smooth surface of endless image-forming layer by plating while partly coating the screen-sleeve.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
64 words
A method for producing a rotary printing screen, comprising the steps of : inserting a metal screen sleeve image supporter made by a plating process into the inside of a metal cylinder; and immersing both said screen sleeve and said metal cylinder in a plating bath in order to coat said screen sleeve with a plated metal and simultaneously to form an image-forming layer.
Claim 2
Independent Claim
64 words
A method for producing a rotary printing screen, comprising the steps of : inserting a metal screen sleeve image supporter made by a plating process into the inside of a metal cylinder; and immersing both said screen sleeve and said metal cylinder in a plating bath in order to coat said screen sleeve with a plated metal and simultaneously to form an image-forming layer.
Claim 3
Independent Claim
77 words
A method for producing a rotary printing screen comprising the steps of: inserting a metal screen sleeve image supporter made by a plating process into the inside of a non-metal cylinder, said non-metal cylinder having a conductive inside surface produced by a chemical plating process; and immersing both said screen sleeve and said non-metal cylinder into a plating bath in order to coat said screen sleeve with a plated metal and simultaneously to form an image-forming layer.
Claim 4
Independent Claim
77 words
A method for producing a rotary printing screen comprising the steps of: inserting a metal screen sleeve image supporter made by a plating process into the inside of a non-metal cylinder, said non-metal cylinder having a conductive inside surface produced by a chemical plating process; and immersing both said screen sleeve and said non-metal cylinder into a plating bath in order to coat said screen sleeve with a plated metal and simultaneously to form an image-forming layer.
Claim 5
Independent Claim
80 words
A method for producing a rotary printing screen, comprising the steps of: forming a metal image-forming layer on an inside surface of a metal cylinder, said layer being a smooth, endless outside surface of a cylindrical member having a thickness in the range of from 5 to 50 microns; inserting within said metal cylinder a cylindrical screen sleeve image supporter, said sleeve being comprised of a metal; and fixing said cylindrical member and said sleeve together by an electroplating process.
Claim 6
Independent Claim
80 words
A method for producing a rotary printing screen, comprising the steps of: forming a metal image-forming layer on an inside surface of a metal cylinder, said layer being a smooth, endless outside surface of a cylindrical member having a thickness in the range of from 5 to 50 microns; inserting within said metal cylinder a cylindrical screen sleeve image supporter, said sleeve being comprised of a metal; and fixing said cylindrical member and said sleeve together by an electroplating process.
Claim 7
Independent Claim
93 words
A method for producing a rotary printing screen, comprising the steps of: forming a metal image-forming layer on an inside surface of a non-metal cylinder, said layer being a smooth, endless outside surface of a cylindrical member having a thickness in the range of from 5 to 50 microns; inserting within said metal cylinder, a cylindrical screen sleeve image supporter, said sleeve being comprised of a non-metal having a surface provided with conductivity by means of a chemical plating process; and fixing said cylindrical member and said sleeve together by an electroplating process.
Claim 8
Independent Claim
93 words
A method for producing a rotary printing screen, comprising the steps of: forming a metal image-forming layer on an inside surface of a non-metal cylinder, said layer being a smooth, endless outside surface of a cylindrical member having a thickness in the range of from 5 to 50 microns; inserting within said metal cylinder, a cylindrical screen sleeve image supporter, said sleeve being comprised of a non-metal having a surface provided with conductivity by means of a chemical plating process; and fixing said cylindrical member and said sleeve together by an electroplating process.
Claim 9
Dependent Claim
36 words
A method for producing a rotary printing screen as in claim 3, wherein said metal image-forming layer having a smooth, endless outside surface is made by a plating process in the inside of a metal cylinder.
Claim 10
Dependent Claim
52 words
A method for producing a rotary printing screen as in claim 4, wherein said metal forming image layer having a smooth, endless outside surface is made by a plating process in the inside of a non-metal cylinder after said cylinder has been provided with conductivity by means of a chemical plating process.
Claim 11
Dependent Claim
40 words
A method for producing a rotary printing screen as in claim 3, further including the step of: forming said screen sleeve image supporter by a plating process wherein nets of fine metal filaments are fixed together by said plating process.
Claim 12
Dependent Claim
39 words
A method for producing a rotary printing screen as in claim 7, wherein said fixing of said fine metal filaments is carried out by the steps of first utilizing a chemical plating process and then utilizing an electroplating process.
