Processing station having a first and a second cylinder for processing a substrate web

A processing station for processing a substrate web supplied and led away with a substantially continuous speed, comprising:

• an impression roller;
• a rotatably mounted tool cylinder on which a first tool plate is securable and which, in use, at a contact area, with insertion of the substrate web, engages the impression roller for carrying out a processing operation on the substrate web;
• and
• a mechanism configured, within one revolution of the tool cylinder, to periodically vary a transport speed of the substrate web at the contact area relative to the rotation speed of the tool cylinder,
• wherein the rotatably mounted tool cylinder includes a first and a second rotatably mounted tool cylinder which can each be provided with a tool plate,
• wherein of the first and second tool cylinders, at any time only one is in an operative state while the other is in a non operative state,
• wherein the operative state is provided in that an impression roller, with insertion of the substrate web, at a contact area is in engagement with the tool cylinder in the operative state,
• wherein the non-operative state is provided in that the non-operative tool cylinder is not in engagement with the substrate web and an impression roller, and
• wherein the non-operative tool cylinder of the first and second tool cylinders is available and accessible for thereon exchanging a tool plate.
