Abstract: A papermaker's fabric includes first and second layers of cross-machine-direction (CD) yarns and a plurality of machine-direction (MD) yarns interwoven therewith and arranged in groups each having a first, two second, and two third MD yarns. The first MD yarn binds with two CD yarns of the first layer and with two CD yarns of the second layer. The second MD yarns bind with only one CD yarn of the first layer and floats over at least two consecutive CD yarns of the second layer. The third MD yarns bind with only one CD yarn of the first layer and floats over at least two consecutive CD yarns of the second layer. The second MD yarns are offset from the third MD yarns in a direction parallel to the MD yarns. The first MD yarn is between the two second MD yarns which are between the third MD yarns so as to form a continuous air channel.

Abstract: A papermaker's fabric, usable with a dryer section on a paper machine, has a first layer and a second layer of cross-machine-direction (CD) yarns. Interwoven with the CD yarns in a duplex weave is a system of MD yarns. The MD yarns are provided in groups of at least two adjacent MD yarns. Each group has one first MD yarn and one or more second MD yarn. The first MD yarn interweaves between the first and second layers of CD yarns, each time binding with only one CD yarn. Each second MD yarn also interweaves between first and second layers of CD yarns, each time binding with only one CD yarn in the first layer, but floating over at least two CD yarns in the second layer. The first MD yarn is between the one or more second MD yarns in its group and those of an adjacent group, and defines a continuous air channel on the surface of the fabric.
