Abstract

The invention provides an improved stopper rod which is made by a method in which a composition to forms the body of the stopper rod is charged into a mould (10), a removable core (12) is positioned into the mould (10) to form a longitudinally-extended bore (31, 41) in the stopper rod body. An externally-threaded removable insert (16) being positioned in the mould in correspondence core (12) to form an internal thread (37, 43) on a portion of the bore and a plate (18) being positioned in the mould to define a flat upper end (35, 40A) of the stopper rod body characterized in that a spacer (22) is positioned between the externally threaded insert (16) and the plate (18) due to which the internal threading (37, 43) in the bore (31, 41) of the rod body is formed spaced from the upper end (35, 40A) when the composition is pressed in the mould. The invention also provides to a mould in which to make the improved stopper rod. 11 claims, 3 figures
