Kind Code:
B2
Abstract:
PURPOSE:To make it possible to decide quality of strap thickness by using a mold having a concave part and a hot water path for a strap in order to form the strap while dipping a pole plate lug into molten lead injected into it. CONSTITUTION:A mold 3, in which a concave part 4 for a strap and a hot water path 5 having smaller width than that are carved, is provided while arranging pole plate lug 2 of a pole plate group 1 on the upper part. Next, molten lead 9 inside a melting pot 7 is injected into the concave part 4 for a strap through the hot water path 5 of a mold 3 for dipping the pole plate 2 into it in order to form a strap 15 furnished with hot water path lead 16. And by inspecting existing hot path lead 16 or its thickness, quality of the thickness of the strap 15 is decided while finally cutting hot path lead 16 for forming the strap. Accordingly, since the part of hot path lead is projected, the inspection is simplified thus being able to decide the quality.
