Abstract

A leading bung seal (BS1) in a magazine (4) is picked up by a bung seal transfer clamp (8) and is positioned between a bung seal receptacle (6) and a bung seal transfer device (10), which are axially aligned. A bung seal expansion pin (18) is advanced to drive the leading bung seal (BS1) into the bung seal receptacle (6), to force it against a resilient grommet (42) therein, and to extend through the bung seal (BS1) so as to expand it. A bung seal expansion sleeve (14) surrounding the expansion pin (18) is then advanced further to expand the bung seal (BS1) and the pin (18) is withdrawn leaving the bung seal (BS1) secured to the expansion sleeve (14) by its own resilience. A lead (L) is then inserted into the expansion sleeve (14), and the expansion sleeve (14) is then withdrawn, leaving the seal (BS1) secured to the lead (L), by its own resilience, after which the bung seal receptacle (6) is opened and the lead (L) with the bung seal (BS1) thereon is removed to a station at which an electrical terminal is crimped to the lead (L) and to the bung seal (BS1).
