Abstract
A process is described in which a tubular bar (27) which is substantially but not entirely filled with flowable solids (28), is closed at one end. To close the tubular bar (27) at its end, a thread (3) is introduced into the tubular bar (27) and is caused to form a ball of thread therein. The thread (3) is preferably introduced into the tubular bar by being blown through a hollow needle (11).
