Abstract
Abstract Method and apparatus for manufacturing plate assemblies for bipolar or semibipolar storage batteries containing bipolar and monopolar plates having positive and/or negative active masses. Forming apparatus is disposed to form on an electrically insulating support material, a plate frame web containing longitudinally continuous and transversely spaced plate frame blanks containing electrically conductive material. Adding apparatus is disposed to add onto the plate frame web containing the plate frame blanks, longitudinally continuous and transversely spaced zones constituted by alternative positive and negative active masses. Cutting apparatus are disposed to cut by transverse and longitudinal cutting lines, plate assembly blanks containing bipolar and/or monopolar plates from the plate frame web containing the active mass zones.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
117 words
Method for manufacturing a plate assembly for a bipolar or semibipolar storage battery comprising monopolar plates containing a positive or negative active mass, and bipolar plates comprising positive and negative active masses, comprising the steps of forming upon an electrically insulating support material, a plate frame web containing longitudinally continuously and transversely-spaced plate frame blanks containing electrically conductive material, adding upon the plate frame web containing the plate frame blanks, zones constituted by alternating positive and negative active masses which are continuous over the longitudinal direction and trnsversely spaced from one another, and cutting the plate blanks into monopolar or bipolar plates with transverse and longitudinal cuts into the plate frame web containing the active mass zones.
Claim 2
Dependent Claim
117 words
Method for manufacturing a plate assembly for a bipolar or semibipolar storage battery comprising monopolar plates containing a positive or negative active mass, and bipolar plates comprising positive and negative active masses, comprising the steps of forming upon an electrically insulating support material, a plate frame web containing longitudinally continuously and transversely-spaced plate frame blanks containing electrically conductive material, adding upon the plate frame web containing the plate frame blanks, zones constituted by alternating positive and negative active masses which are continuous over the longitudinal direction and trnsversely spaced from one another, and cutting the plate blanks into monopolar or bipolar plates with transverse and longitudinal cuts into the plate frame web containing the active mass zones.
Claim 3
Dependent Claim
30 words
The method of claim 1, wherein the plate frame web is formed upon the support material by casting a lead blank to constitute plate frames and wiring connecting the same.
Claim 4
Dependent Claim
23 words
The method of claim 2, comprising the additional step of hot-rolling the casted lead blank and support material to join the same together.
Claim 5
Dependent Claim
27 words
The method of claim 2, comprising the additional step of pressing the support material and the lead blank against a casting drum to join the same together.
Claim 6
Dependent Claim
45 words
The method of claim 1, comprising the additional step of applying a layer of separator material to the plate blanks prior to the step of cutting, whereby all cutting of blanks and material to form the plates may be carried out in a single step.
Claim 7
Dependent Claim
38 words
The method of claim 1, comprising the additional steps of stacking the thus-cut plates with a layer of separator material interposed therebetween, in a casing, and injecting electrically-insulating material into the casing to fill spaces between adjacent plates.
