Abstract
The liners are formed from flat corrugated paper sheets that are stored on edge in a magazine. A vacuum picker transfers single sheets to a conveyor and they are creased on the upper surface by disc blades. The creased sheets are fed between narrow upper and lower conveyor belts and drawn through plow elements which fold the sheets to form liners. The formed liners are carried by gripping heads of an overhead chain conveyor to a constantly moving bucket conveyor. The axis of the chain conveyor is set at an acute angle to the axis of the bucket conveyor and the gripping heads are rotated by cam elements to align the liners with the conveyor buckets.
