ABSTRACT:
The present invention describes an apparatus for creasing and cutting an endless web of cardboard. A pair of rollers operates on the web while another pair of rollers is in an inactive position where the tools mounted on the rollers can be moved to new positions. When it is time for different operations to be performed on the web the original rollers working on the web are removed from their working position and the rollers previously in the inactive position are moved to the working position. The rollers now in the working position have had their tools aligned for the new operation while they were in the inactive position. The rollers originally in the working position are now in an inactive position where the tools on these rollers can be aligned for another operation. Each pair of rollers is independently driven to spin independent of the position of the roller. This independent driving of the pairs of rollers allows the rollers in the inactive position to be spun up to speed before being moved into the working position.
