ABSTRACT:
A moulding apparatus (10) for moulding a strap on to a group of battery plates including a mould block (14) with moulds (24), each of which has an inlet weir (28) and an outlet weir (29). The ridge (30) of these weirs is effectively a knife edge but includes a thermal break. This construction allows rapid processing whilst avoiding the formation of solid tails.
