<p>Apparatus for subdividing a paper web into a series of discrete sheets and for transporting the sheets to a processing station has a cross cutter whose knife holders can be driven at several speeds, and a sheet intercepting device downstream of the nip of the holders. The position of the entire intercepting device is changed in automatic response to changes in the speed of the knife holders to ensure that the inlet of the intercepting device can receive the leaders of successive sheets, even though the direction of advancement of such leaders is likely to change, e.g., in response to more or less pronounced curling, as a result of acceleration or deceleration of the knife holders and as a function of the thickness and/or composition of the web.</p> |
