Methods and apparatus, including computer program products for package waste management in a filling machine. A waste event is detected during operation of the filling machine. The waste event is associated with a waste event detection point in the filling machine and a corresponding web segment position of the packaging material. One or more filled packages to be discarded are identified. The identification is made based on a predetermined distance along a path to be traversed by the packaging material from the waste event detection point to a waste chute of the filling machine. The predetermined distance is expressed in a standardized length measurement format. In response to determining that the web segment position has progressed a distance equaling the predetermined distance, one or more packages formed at or in close proximity to the web segment position are ejected through the waste chute.

A tensioning device for a chain driven jaw system in a package filling machine is disclosed. The chain driven jaw system has a fixed cam and a chain as a follower. The tensioning device comprises a chain tensioning element shaped and angled so to receive the chain on an outer surface thereof configured to be directed away from a center of the chain driven jaw system, wherein the chain tensioning element comprises a pivot connection, and wherein the chain tensioning element is configured to be integrated with the fixed cam at the pivot connection such that the chain tensioning element abuts the fixed cam at the pivot connection and can move to tension the chain. A chain driven jaw system and a related method is also disclosed.
