METHOD AND ARRANGEMENT FOR MANUFACTURING GRID FOR LEAD BATTERY PLATE

摘要

Method and arrangement for manufacturing grids for lead battery plates, forming a patterned grid of lead or lead alloy within a frame. A sheet of fibreglass based insert (7) is introduced between a pair of casting belts (1), which move along a travel path having a contacting section. Molten lead or lead alloy from a dispensing means (8) is applied on both sides of the sheet of fibreglass based insert (7) before reaching the contacting section, and leaving that a continuous plurality of separate grids (13) are formed on the continuous insert (7) at the output. A cooling effected by a cooler (10) is applied to at least a part of the contacting section during travelling of the casting belts (1).
