ABSTRACT:
The present invention is a method and apparatus for eliminating the flutter of a paper web in the dryer section of a papermaking machine between two single felt configurations in which the web is transferred from a dryer fabric of a first configuration onto a dryer fabric of a second configuration along a common run of the fabrics, the transfer being effected from one fabric to the other by means of a vacuum transfer roll, with the second configuration dryer fabric being brought into contact with the web and around which the fabric is winding, whereby on the side of the first configuration dryer fabric upstream of a contact point between the web carried thereon and the second configuration dryer fabric winding around the vacuum transfer roll there is provided a vacuum zone defined by the first configuration dryer fabric for retaining the web in contact with the first configuration dryer fabric. At a location downstream of the contact point in the traveling direction of the first configuration dryer fabric, air is blown from the side of the first configuration dryer fabric released from the web through the fabric into a gap formed between the second configuration dryer fabric lying on the vacuum transfer roll together with the web and the first configuration dryer fabric released from the web.
