Abstract
Method and apparatus for filling a cable core unit with powder in a fluidized bed in which the unit is vibrated laterally by introducing energy pulsations into the bed, the pulses being transmitted as successive waves through the powder particles to transfer the energy to the unit and set up the vibration. In preferred constructions, the pulsations are set up by a reciprocating piston means disposed beneath the upper surface of the powder. There may be two or more piston means spaced in the feed path direction for the unit or a single piston extending.
