Abstract

An apparatus for conveying viscous material from a container having a base and an upwardly-extending shell includes: a follower plate movable towards and away from the base adjacent to the shell inner surface facing the interior and having an outlet and at least one deaeration and/or aeration opening; a deaerator for sucking air through the deaeration opening(s) and/or an aerator for introducing compressed air through the aeration opening(s); a lifting/lowering device for lifting/lowering the plate; a control for alternately controlling the lifting/lowering device in a movement mode and the deaerator or aerator in a deaeration or aeration mode, the lifting/lowering device having at least one vertical holding rod connected to a plate upper side, the plate being vertically movable in a limited manner relative to the rod; and a sensor for detecting and transmitting to the control upper and lower end plate positions relative to the rod.
