ABSTRACT:
A structure for bringing about transfer of a paper web from the press section to the drying section of a paper machine during travel of an initial portion of a web from the press section to the drying section as well as subsequently when the travel of the web between these sections has become stabilized. A pair of rolls are situated between the last roll of the press section and the first roll of the drying section to support and guide the web during travel thereof between the press section and drying section. In addition, a weighting roll is provided to cooperate with that one of the above pair of rolls which is nearer to the drying section to define with the latter roll a nip through which an initial portion of the web travels until the operating conditions have become stabilized. A control structure is connected with the weighting roll to control the pressure at this nip as well as to displace the weighting roll away from that one of the pair of rolls which is nearer to the drying section after the travel of the web has become stabilized.
