The cylinders carry means for effecting the cutting and creasing of the sheets advanced into the nip. The apparatus also includes means for advancing the sheets in a registered condition into the nip. The means for advancing the sheets into the nip comprises feed roll means defining a feeding nip located in advance of the cutting and/or creasing nip. Gripper means engages the leading edge of a sheet and carries the leading edge of the sheet into the feeding nip and then releases the leading edge of the sheet so that the sheet is fed into the cutting and creasing nip by the feed roller means. Suitable means is provided for guiding the movement of the sheet from the feeding nip and to the cutting and creasing nip.
