Abstract

An apparatus for conveying viscous material from a drum-like container with a container bottom and a circumferential container wall extending from the container bottom to a container upper side and being open at the container upper side has, for closing the container a follower plate having a material outlet attached to a conveyor pump. The follower plate has an annularly circumferential wiper ring that has a radially outwardly extending contacting part for contact against an inside face, turned toward the follower plate, of the container wall. The contacting part can be pressurized with a variable pressing force for pressing against the inside face (36) of the container wall. The follower plate is mounted by moans of at least one vertically extending retaining rod on a horizontally extending crosspiece mounted on or close to a first end on a lifting device for raising and lowering of the crosspiece. Its second end is free.This task is accomplished by an apparatus having the features according to one aspect of the invention as well as by a method having the features according to another aspect of the invention. Advantageous further developments of the invention are subject matter d…
