A buckle-folding unit for a folding machine has at least one buckle plate (10) including a plurality of plate-bar structures (12) which are spaced apart one beside the other in a single plane, each of the plate-bar structures (12) including two plate bars (14, 16) spaced apart from one another to form a gap (18) therebetween, the gaps (18) being located in a single plane. The plate bars (14, 16) have an inner recess (33) in the side thereof which is directed toward the gap (18). A sheet-stopping device (22), which can be displaced in the longitudinal direction of the plate-bar structures (12), is arranged transversely to the plate-bar structures (12) and passes through the gaps (18) of the plate-bar structures (12). The sheet-stopping device (22) has a plurality of outer stops (26), each of the outer stops (26) being arranged between adjacent plate-bar structures (12), and a plurality of inner stops (34), which are arranged within the plate-bar structures (12), each of the inner stops (34) extending into an inner recess of the plate bars (12, 14). The inner stops (34) are connected to adjacent outer stops (26) via a connecting crosspiece (34), the width (b) of the connecting crosspiece (34), in the direction perpendicular to the plane of the gaps (18), being smaller than the height of the gap (18).
