A paper machine carrier drum apparatus comprising:
- a drivable carrier drum having an axis;
- a cylinder disposed adjacent the carrier drum, said cylinder disposed parallel to the carrier drum axis and swivelable about a first peripheral region of the drum;
- a guide roll disposed upstream of the carrier drum with respect to a direction of travel of a paper web through the apparatus;
- and
- a pressure roll disposed adjacent to said drum and adjustably pressable against said drum, said pressure roll movable to a plurality of positions about a second peripheral region of the drum, the pressure roll and the drivable carrier drum defining a nip for passage of a material web therethrough, the drivable carrier drum, the guide roll, and the pressure roll oriented with respect to one another to provide a free draw of a material web directly between the guide roll and the nip defined by the pressure roll and the drivable carrier drum.
