Abstract
A lead delivery apparatus for a cast on strap machine is arranged to deliver a predetermined volume of molten lead to a mould. The apparatus includes a first needle valve, a second needle valve, and a housing. The housing includes a reservoir having an inlet and an outlet. The reservoir inlet is in fluid communication with a molten lead supply. The reservoir is supplied with molten lead during use such that the molten lead in the reservoir is maintained at a constant height. A volume block has an inlet, an outlet and a through cavity and the volume block inlet is in fluid communication with the reservoir outlet. The through cavity together with the second needle valve defines the predetermined volume of molten lead received from the reservoir.
