A feeding device for feeding stacks of standing flat-folded cartons to a receiving station, comprising a conveyor track having a flat bearing plane adapted to support the stacks, where the conveyor track comprises at least two rows of teeth where each row of teeth comprises a plurality of spaced apart teeth adapted to support the stacks of flat-folded cartons, where the teeth can be positioned in either an erected position or in a folded position, and where the feeding device comprises a guide track arranged along the bearing plane adapted to hold the teeth in the selected position, and where the guide track ends at an end region of the conveyor track, such that the teeth are unsupported at the end region. The advantage of the invention is that stacks of flat-folded cartons can be merged continuously at an outfeed region.

The invention provides a manufacturing system for processing a web, the system comprising a rigid frame with a plurality of processing stations; an endless belt which is movable relative to the frame; a track for guiding the endless belt between the processing stations; and a drive structure for advancing the belt along the track, To enable more flexible processing time at each processing station and to make better use of the space along the track, the system facilitates movement of a web at different speed at different locations along the track.
