The machine includes a plurality of sleeves 11 for retaining a capsule cap C and associated plungers 51. Within each plunger there is a shaft 62 arranged to reciprocate and carrying at its upper end a plunger head 66 which is biased upwardly by a spring 63. The plunger and plunger head together partially define an annular space adapted to retain sealing fluid or to communicate with a sealing fluid supply via duct 67 when the plunger is urged into contact with the interior of a capsule cap. The machine is constructed so that when the plunger head is depressed by contact with the interior of a cap sealing fluid is applied to the said interior. <IMAGE> |
