Abstract
Paper sheets which are creased during transport from a magazine to a folding station are delivered between the outer side of a straight reach of an elastic belt conveyor and a row of folding rollers whose radially outwardly tapering peripheral portions extend into a groove in the outer side of the conveyor whereby the rollers fold the sheets along the creases. The straight reach of the conveyor is propped from the inside by a set of rollers which are adjustable toward and away from the row of folding rollers to account for different thicknesses, stiffnesses and/or other characteristics of the sheets. The taper of peripheral portions of successive folding rollers increases in the direction of transport of sheets.
