Abstract
Method of enveloping a battery plate in a heat-fusible fibrous separator material (e.g., fibrous glass mat) including the step of tacking the mat to itself by means of an electric arc.
Claims6
A method of enveloping a battery plate in a heat-fusible, fibrous separator material, said plate having a pair of opposing faces defined by a plurality of edges, said method comprising the steps of:
- a. overlying each said face of a said plate with a sheet of said separator material such that each said sheet has at least one perimetrical portion extending outboard a said edge of said plate and lies adjacent the perimetrical portion of the other of said sheets;
- b. pressing said adjacent perimetrical portions together between a set of electrodes;
- c. striking an electric arc between said electrodes sufficient to fuse said perimetrical portions together at the situs of said arc;
- and
- d. holding said perimetrical portions together until said fused perimetrical portions cool sufficiently to bond said perimetrical portions together.
A method of enveloping a battery plate in a heat-fusible, fibrous separator material, said plate having a pair of opposing faces defined by a first pair of opposing edges and a second pair of opposing edges substantially perpendicular to said first pair of edges said method comprising the steps of
- a. folding a sheet of said separator material around one of the edges of said first pair of edges, said sheet having first and second planar sections each overlying a said face and having a pair of opposing perimetrical portions extending outboard said second pair of edges such that a perimetrical portion of one of said sections lies adjacent a perimetrical portion of said second section;
- b. pressing said adjacent perimetrical portions together between a set of electrodes;
- c. striking an electric arc between said electrodes sufficient to fuse said perimetrical portions together at the situs of said arc;
- and
- d. holding said perimetrical portions together until said fused perimetrical portions cool sufficiently to bond said perimetrical portions together.
