Title:
APPARATUS AND METHOD FOR FORMING A TERMINAL
Document Type and Number:
WIPO Patent Application WO2003063265
Kind Code:
A3
Abstract:
The invention relates to apparatus and methods for forming a terminal on a battery. Terminal forming apparatus ( 11 ) has a mould ( 12 ) with a cavity ( 26 ) which is intended to encircle the post and bush assembly ( 22, 25 ) of a battery box ( 10 ). The mould cavity ( 26 ) is formed with an open upper mouth ( 27 ) and a lateral inlet/outlet ( 28 ) which connects with the feed channel ( 13 ). Inlet ( 28 ) is defined by a weir ( 29 ) which acts as a constant height device to define the final filling height of the mould cavity ( 26 ). This arrangement allows over filling of the mould above the height of the weir ( 29 ) and subsequent dropping of that level to the height of the weir ( 29 ). This enables the terminal to be formed at precisely the correct height without the need for any metering of the lead.
