Abstract

An arrangement havign a closing member for filling mouthpiece of a filling machine for filling material of a pasty up to a chunky or lumpy consistency, whereby during the filling packaging containers are stepwise moved underneath the filling mouthpiece. When the filling material is very tough and hardens rapidly, it is desirable that the heap-like remanent tip Z of the filling material, which remains after the filling operation,is disposed in the middle of each packaging container. This achieved by means of a closing member that includes two identical oppositely rotatably movable cylinders, each one of which is provided with a rectangular recess. These recesses extend to each one of the cylinders in such a way that a disc-shaped base portion and a shank remain, which shank has a circular segment-shaped cross-section. The cylinders are mounted in a bore which is transverse to the longitudinal axis of the filling mouthpiece and are mutually coaxially arranged and are positioned in such a way that the shank of one cylinder extends into the recess of the other cylinder. The cylinders move jointly and in synchronization with the packaging container therepast and are actuated for achieving an opening and closing motion. In the open position the inner sides of the shanks align with the filling channel of the filling mouthpiece. In the closed position the edges of the shanks precisely meet at the longtiduinal aixis of the filling mouthpiece and thereby pinch off the filling material.
