Abstract
Abstract A woven fabric cell plate for alkaline cell accumulators, which alternates in at least one of the warp and weft directions between areas of double layer and areas of combined single layer. The active mass of the accumulator is retained between the layers of the double layer areas. At least one of the warp and weft may be formed of metal wire, or one of the layers of the double layer areas may be formed of metal wire while the other layer is formed of a second material.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
89 words
A cell plate for alkaline cell accumulators, said cell plate comprising a fabric including warp and weft, wherein said fabric includes areas alternating in at least one of the warp and weft directions, of double and single weaving forming alternating areas of double layer and combined single layer fabric, wherein said double layer areas form receptacles for containing the active mass, and wherein one of the layers of said double layer areas is formed of metal wires and the other of said layers is formed of a plastic thread.
Claim 2
Dependent Claim
89 words
A cell plate for alkaline cell accumulators, said cell plate comprising a fabric including warp and weft, wherein said fabric includes areas alternating in at least one of the warp and weft directions, of double and single weaving forming alternating areas of double layer and combined single layer fabric, wherein said double layer areas form receptacles for containing the active mass, and wherein one of the layers of said double layer areas is formed of metal wires and the other of said layers is formed of a plastic thread.
Claim 3
Dependent Claim
21 words
A cell plate as claimed in claim 1, wherein said double layer areas form tubular receptacles for containing the active mass.
Claim 4
Dependent Claim
22 words
A cell plate as claimed in claim 1, wherein said double layer areas form pocket shaped receptacles for containing the active mass.
Claim 5
Dependent Claim
36 words
A cell plate as claimed in claim 1, wherein said fabric comprises materials of different elasticity, such that, after the fabric is woven, at least one of the layers of said double layer areas is convex.
Claim 6
Dependent Claim
99 words
A cell plate for alkaline cell accumulators, said cell plate comprising a fabric including warp and weft, wherein metal wire forms at least one of the warp and weft, wherein said fabric includes areas alternating in at least one of the warp and weft directions of double and single weaving forming alternating areas of double layer and combined single layer fabric, wherein said double layer areas form receptacles for containing an active mass, and wherein a first layer of said double layer areas include wires of a first metal and a second layer includes wires of a second metal.
Claim 7
Dependent Claim
99 words
A cell plate for alkaline cell accumulators, said cell plate comprising a fabric including warp and weft, wherein metal wire forms at least one of the warp and weft, wherein said fabric includes areas alternating in at least one of the warp and weft directions of double and single weaving forming alternating areas of double layer and combined single layer fabric, wherein said double layer areas form receptacles for containing an active mass, and wherein a first layer of said double layer areas include wires of a first metal and a second layer includes wires of a second metal.
