Abstract
Abstract A device for sealing the tubes (4) in a tubular electrode plate of an electrochemical lead cell comprising a top and a bottom part. The top part consists of separate sleeves (10) for each tube (4), which optionally are arranged on a connecting strip (14), each sleeve (10) having a bottom with a central through hole with a diameter corresponding to the diameter of the spine (2), which is to protrude therethrough, and a wall, the periphery of which corresponds to the periphery of the tubular casing (4) to butt thereagainst FIG. 2.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
158 words
Device for sealing the tubes in a tubular electrode plate of an electrochemical lead cell, comprising a tubular electrode plate having a lead grid with a conductor common to all tubes, a top bar (1), from which separate spines (2) extend, each one being surrounded by an active material (5) enclosed in a tubular casing (4), consisting of a top part for sealing the upper ends of the tubes facing the top bar and a bottom part for sealing the lower, free ends of the tubes, characterized in that the top sealing part including separate sleeves (10) for each tube, which are arranged on a connecting strip (14), each sleeve having a bottom (12) with a central through hole (13) with a diameter corresponding to the diameter of the spine (2), which is to protrude therethrough, and a wall (11) the periphery of which corresponds to the periphery of the tubular casing (4) which is to butt thereagainst.
Claim 2
Dependent Claim
158 words
Device for sealing the tubes in a tubular electrode plate of an electrochemical lead cell, comprising a tubular electrode plate having a lead grid with a conductor common to all tubes, a top bar (1), from which separate spines (2) extend, each one being surrounded by an active material (5) enclosed in a tubular casing (4), consisting of a top part for sealing the upper ends of the tubes facing the top bar and a bottom part for sealing the lower, free ends of the tubes, characterized in that the top sealing part including separate sleeves (10) for each tube, which are arranged on a connecting strip (14), each sleeve having a bottom (12) with a central through hole (13) with a diameter corresponding to the diameter of the spine (2), which is to protrude therethrough, and a wall (11) the periphery of which corresponds to the periphery of the tubular casing (4) which is to butt thereagainst.
Claim 3
Dependent Claim
55 words
Device according to claim 1, characterized in that the top sealing part includes a top strip with separate sleeves (10) for each tube, each sleeve having an outer diameter corresponding to the inner diameter of the tubular casing (4), so that after sealing the tubular casing (4) tightly surrounds the wall (11) of the sleeve.
Claim 4
Dependent Claim
96 words
Device according to claim 1 or 2, characterized in that the bottom sealing part includes separate sleeves (15) for each tube, which are arranged on a connecting strip (18) forming a bottom bar, each sleeve having an outer wall (16) with an inner diameter corresponding to the outer diameter of the tubular casing (4) and an inner wall (17) with an inner diameter corresponding to the diameter of the spine (2), so that, after sealing, the outer wall (16) tightly surrounds the tubular casing (4) and the inner wall (17) surrounds and centers the spine (2).
Claim 5
Dependent Claim
35 words
Device according to any one of claims 1 or 2 characterized in that the part for sealing is manufactured of a plastic material, selected from the group consisting of polystyrene, polypropene, polyethylene and polyvinyl chloride.
