Abstract
A drop former includes a supply vessel having bottom discharge openings for discharging a free-flowing viscous mass. An endless perforated belt rotates around front and rear guide drums such that a lower run of the belt travels toward the rear guide drum while passing across the discharge openings of the vessel to periodically open those openings and allow drops of the mass to fall onto a cooling conveyor. A collecting space is formed beneath the rear guide drum for collecting residual mass from the belt. A recirculation mechanism recirculates that collected residual mass back to a location adjacent the discharge openings.
