Abstract
The bottom plate mechanism has an adaptor plate (10) on which bottom plates of one or more moulds are mounted. The adaptor plate contains passages (14,20) which connect an inlet (16) thereof to a source of vacuum through a filter (72). In order that the filter may be rapidly changed, the adaptor plate is supported by a vertically-extending tubular member (24) which is supported for height adjustment, with a cylindrical projection (12) of the adaptor plate telescopically received within the tubular member. The arrangement is such that the adaptor plate (10) may be lifted away from the tubular member (24) so that the cylindrical projection (12) and filter (72), which is mounted on the cylindrical projection, leave the tubular member.
