Abstract
A method for applying a sealant to the surface of an object includes forming an annular dose of synthetic plasticised material supplied from an extruder, depositing the dose on the surface of object and compression forming the dose to form a seal. The extruder includes an annular outlet which is opened and closed to deposit successive doses. Each dose that exits the annular outlet is separated from a supply of plasticized material in the extruder.
