A belt designed for lead acid battery plate pasting that is rendered dimensionally stable and incompressible and is also rendered hydrophobic to allow water handling without absorption and subsequent contamination of lead oxide into the structure.
Claims22
A battery paster belt comprising of:
- a first ply of an endless fabric structure produced from high modulus monofilament yarns;
- a second ply comprised of two to five layers of monofilament flat fabric, each needled with a layer of fibrous batt, and wrapped around the high modulus filament first ply;
- a third ply made of successive layers of batt fiber, wrapped around the second ply and attached to the second ply;
- and
- a fourth ply of monofilament endless fabric structure attached to the third ply through needling of a layer of batt fiber.
