A web transporting device usable in a rotary printing press or folder, includes a rotatably driven transport roller having a fixed axis and at least one engagable nip roller having an axis substantially parallel to the fixed axis and being engagable with the driven transport roller. The engagable nip roller has a length corresponding to a maximum width of the web processable in the printing press. A removable nip sleeve is provided which is axially mounted on the engagable nip roller. The removable nip sleeve has at least one ring-shaped annular gap disposed axially along its length which allows the web to ripple as it passes through the web transporting device without causing permanent wrinkles or creases to form in the web. A counterbalancing mechanism is also provided which stabilizes the engagable nip roller in a maintenance position as the removable nip sleeve is replaced.
