PURPOSE: Provided is a papermaker's fabric of the on-machine-seamable variety, such as an on-machine-seamable press fabric for the press section of a paper machine. CONSTITUTION: An on-machine-seamable papermaker's fabric is characterized by comprising: a system of machine-direction(MD) yarns and a system of first cross-machine-direction(CD) yarns, wherein the yarns of the system of MD yarns are interwoven with the yarns of the system of first CD yarns in a first weave pattern to form a body of the papermaker's fabric in a rectangular shape with a length, a width, two lengthwise edges and two widthwise edges; the MD yarns extend back and fourth continuously for the length of the papermaker's fabric between the two widthwise edges; and the MD yarns further from seaming loops along each of the two widthwise edges; a system of second CD yarns, wherein the yarns of the system of second CD yarns are interwoven with the yarns of the system of MD yarns in a first region along one of the two widthwise edges of the papermaker's fabric between the system of first CD yarns and the seaming loops in a second weave pattern; there are more than two second CD yarns in the system of second CD yarns, wherein the first region differs from the body by at least one of the following: a) the denier of at least some of the second CD yarn is different from the denier of the first CD yarns; b) the spacing between at least some of the second CD yarns is different from the spacing between the first CD yarns; and c) the second weave pattern is different from the first weave pattern; a system of third CD yarns is interwoven with the yarns of the system of MD yarns in a second region along the other of the two widthwise edges of the papermaker's fabric between the system of first CD yarns and the seaming loops in a third weave pattern; and there are more than two third CD yarns in the system of third CD yarns, wherein the second region differs from the body by at least one of the following: a) the denier of at least some of the third CD yarns is different from the denier of the first CD yarns; b) the spacing between at least some of the third CD yarns is different from the spacing between the first CD yarns; and c) the third weave pattern is different from the first weave pattern.
