Abstract
Abstract A composite of several materials constructed to form a printing disc, of the type used in high speed printers. The printing disc is manufactured in separate stages in order to achieve characteristics within the final assembly that are necessary for high speed quality printing. The assembled printing disc comprises a disc shaped member of flexible plastic. The hub of the disc has radially extending arms which each unite with a print head base member. The print head base member is plated with a layer of metal.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
174 words
A method of making a printing disc for use in a serial printing apparatus, comprising the steps of: A. molding a first member comprising an annular shaped ring member having a font of characters extending inwardly therefrom, each character disposed upon an individual print head base member, said base member having a character face and a bonding face disposed from said character face, said bonding face containing an interlock extension extending outwardly therefrom; B. molding a second member comprising a disc shaped base having a radially extending plurality of arms, one arm for each base member, said arms each containing an aperture in an outer extending end portion thereof for receipt of a corresponding interlock extension of a respective character base member; C. interlocking said plurality of arms each with a corresponding base member by inserting each respective interlock extension into a corresponding arm aperture to form a composite structure between said first and second members; and D. removing the annular shaped ring member from the resulting composite structure to form a printing disc.
Claim 2
Independent Claim
174 words
A method of making a printing disc for use in a serial printing apparatus, comprising the steps of: A. molding a first member comprising an annular shaped ring member having a font of characters extending inwardly therefrom, each character disposed upon an individual print head base member, said base member having a character face and a bonding face disposed from said character face, said bonding face containing an interlock extension extending outwardly therefrom; B. molding a second member comprising a disc shaped base having a radially extending plurality of arms, one arm for each base member, said arms each containing an aperture in an outer extending end portion thereof for receipt of a corresponding interlock extension of a respective character base member; C. interlocking said plurality of arms each with a corresponding base member by inserting each respective interlock extension into a corresponding arm aperture to form a composite structure between said first and second members; and D. removing the annular shaped ring member from the resulting composite structure to form a printing disc.
Claim 3
Dependent Claim
18 words
The method of making a printing disc of claim 1, wherein said first molded member is injection molded.
Claim 4
Dependent Claim
18 words
The method of making a printing disc of claim 1, wherein said first molded member is compression molded.
Claim 5
Dependent Claim
18 words
The method of making a printing disc of claim 1, wherein said second molded member is injection molded.
Claim 6
Dependent Claim
36 words
The method of making a printing disc of claim 1, further comprising the step of: E. plating said first molded member with a layer of metal at least about the character faces of said base members.
Claim 7
Dependent Claim
46 words
The method of making a printing disc of claim 1, wherein the interlocking of said plurality of arms with said respective base members further includes the step of ultrasonically bonding the arms and base members together after inserting said interlock extension into a corresponding arm aperture.
Claim 8
Dependent Claim
53 words
The method of making a printing disc of claim 1, wherein the interlocking of said plurality of arms with said respective baSe members further includes the step of heating an immediate area surrounding the apertures to bond the arms and base members together after inserting said interlock extensions into their corresponding arm apertures.
Claim 9
Dependent Claim
34 words
The method of making a printing disc of claim 1, wherein the interlocking of said plurality of arms with said respective base members is accomplished by press-fitting the interlock extensions into their corresponding apertures.
Claim 10
Independent Claim
131 words
A method of making a printing disc for use in a printing apparatus; comprising the steps of: A. molding a first disc shaped member having a plurality of radially extending flexible arms; B. molding a second member having a general annular configuration, and including a plurality of interconnected radially extending character printing types, the number and relative positions of said printing types corresponding to that for the number of radially extending flexible arms; C. securing said second member to said first member by connecting each of said printing types about respective corresponding outer ends of each of said flexible arms; and D. severing said second member at a plurality of points so that each of said character types is capable of independent movement with its associated arm through a printing stroke.
Claim 11
Independent Claim
131 words
A method of making a printing disc for use in a printing apparatus; comprising the steps of: A. molding a first disc shaped member having a plurality of radially extending flexible arms; B. molding a second member having a general annular configuration, and including a plurality of interconnected radially extending character printing types, the number and relative positions of said printing types corresponding to that for the number of radially extending flexible arms; C. securing said second member to said first member by connecting each of said printing types about respective corresponding outer ends of each of said flexible arms; and D. severing said second member at a plurality of points so that each of said character types is capable of independent movement with its associated arm through a printing stroke.
Claim 12
Independent Claim
141 words
A method of making a printing disc for use in a printing apparatus, comprising the steps of: A. forming a first disc shaped member of flexible material, said disc shaped member having a plurality of radially extending flexible arms, said arms each having an end portion for receipt of a corresponding charcter element; B. forming a second member comprising a plurality of individualized but connected character elements, said second member being composed of a durable hard material of a hardness which is relatively harder than said flexible material; C. securing the first and second member together by joining each character element with a respective flexible arm end portion; and D. removing material from said second member so as to provide a composite printing disc assembly having character elements which are mutually separated and capable of independent movement through individual printing strokes.
Claim 13
Independent Claim
141 words
A method of making a printing disc for use in a printing apparatus, comprising the steps of: A. forming a first disc shaped member of flexible material, said disc shaped member having a plurality of radially extending flexible arms, said arms each having an end portion for receipt of a corresponding charcter element; B. forming a second member comprising a plurality of individualized but connected character elements, said second member being composed of a durable hard material of a hardness which is relatively harder than said flexible material; C. securing the first and second member together by joining each character element with a respective flexible arm end portion; and D. removing material from said second member so as to provide a composite printing disc assembly having character elements which are mutually separated and capable of independent movement through individual printing strokes.
