ABSTRACT:
A method and apparatus for introducing powder into a pocket (32) using a dosator (10) having an elongate cavity with an open end and a plunger (12) opposite the open end moveable along the cavity so as to define, between the plunger (12) and the open end, a space of variable volume, the method including, with the plunger (12) defining a volume greater than that of the pocket (32), inserting the open end into a source of powder so as to fill the volume with powder, positioning the open end over the pocket, driving the plunger so as to expel powder from the open end into the pocket and compress it to a predetermined bulk density and removing the open end from the pocket so as to leave the pocket full of powder with the predetermined bulk density.
