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