Abstract

The drive has at least one piezoelectric vibration stimulator (9) with a piezoelement mounted in a housing of the stimulator so as to be able to vibrate. The piezoelement has a drive connection to an imbalance wt. mounted so as to be free to vibrate in the housing of the stimulator. The housing is a mounted on a mould (3), a vibrating table or another part to be set vibrating.
