Abstract
Abstract A method of making an electrode printing head comprises the making of two separate sheet metal parts each formed of a series of juxtapositioned, spaced electrodes held together by at least one interconnecting web; and securing the two sheet metal parts to insulating components of the printing head in such a manner that the electrodes of the two parts are in a non-contacting, intermeshing relationship with respect to one another, whereby the electrodes of the one and the other sheet metal part alternate with one another and form an electrode row on the printing head. Subsequent to the securing step, the interconnecting webs are removed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
121 words
In an electrode printing head having a plurality of strip-shaped electrodes arranged in a row in a juxtapositioned, mutually insulated, spaced relationship and being supported in insulating means forming part of the printing head, the improvement wherein said row of electrodes being constituted by electrodes of identically shaped first and second sheet metal parts, said first sheet metal part being in a reversed position with respect to said second sheet metal part and the electrodes of said first sheet metal part being in an intermeshing relationship with the electrodes of said second sheet metal part, whereby each electrode of said first sheet metal part being situated, without touching, in the space provided between adjacent electrodes of said second sheet metal part.
Claim 2
Dependent Claim
121 words
In an electrode printing head having a plurality of strip-shaped electrodes arranged in a row in a juxtapositioned, mutually insulated, spaced relationship and being supported in insulating means forming part of the printing head, the improvement wherein said row of electrodes being constituted by electrodes of identically shaped first and second sheet metal parts, said first sheet metal part being in a reversed position with respect to said second sheet metal part and the electrodes of said first sheet metal part being in an intermeshing relationship with the electrodes of said second sheet metal part, whereby each electrode of said first sheet metal part being situated, without touching, in the space provided between adjacent electrodes of said second sheet metal part.
Claim 3
Independent Claim
139 words
A method of making an electrode printing head of the type that includes a plurality of strip-shaped electrodes arranged in a row in a juxtapositioned, mutually insulated, spaced relationship and being supported in insulating means forming part of the printing head, comprising the steps of a. making two identically configured sheet metal parts each formed of a series of juxtapositioned, spaced electrodes held together by at least one interconnecting web; b. securing both sheet metal parts to said insulating means in a reversed position and in an intermeshing relationship with respect to one another, whereby the electrodes of the one sheet metal part alternate with the electrodes of the other sheet metal part and whereby the electrodes of the one and the other sheet metal part together form said row; c. subsequent to step (b), removing said interconnecting web.
Claim 4
Independent Claim
139 words
A method of making an electrode printing head of the type that includes a plurality of strip-shaped electrodes arranged in a row in a juxtapositioned, mutually insulated, spaced relationship and being supported in insulating means forming part of the printing head, comprising the steps of a. making two identically configured sheet metal parts each formed of a series of juxtapositioned, spaced electrodes held together by at least one interconnecting web; b. securing both sheet metal parts to said insulating means in a reversed position and in an intermeshing relationship with respect to one another, whereby the electrodes of the one sheet metal part alternate with the electrodes of the other sheet metal part and whereby the electrodes of the one and the other sheet metal part together form said row; c. subsequent to step (b), removing said interconnecting web.
Claim 5
Dependent Claim
28 words
A method as defined in claim 1, wherein said sheet metal parts are made of a chromium-nickel steel alloy and said sheet metal parts are made by etching.
Claim 6
Dependent Claim
16 words
A method as defined in claim 1, wherein said sheet metal parts are made by stamping.
Claim 7
Dependent Claim
16 words
A method as defined in claim 1, wherein said sheet metal parts are made by etching.
