Abstract
In a method for welding closed one end of each of a multiplicity of open-ended tubes suitable for use as brachytherapy capsules (100), each tube is loaded into a holder (52), brought to a welding station (80), has one end welded closed and is then released from the holder (52). A number of holders can 2 be arranged on the periphery of a rotatable member (50), each holder being loaded with a tube at a first station, and then carrying the tube to a welding station (80) and an ejection station (90). The tubes can be loaded into the holders individually by means of an escapement mechanism (40). The invention also extends to apparatus for carrying out the method.
