Abstract: A method for seaming the ends of a papermaker's fabric during installation on papermaking equipment provides a base fabric having at least a first batt needled thereto such that one end of the batt extends beyond the corresponding end of the base fabric a sufficient distance to overlap the opposing end of the batt when the ends of the base fabric are joined. The opposing ends of the base fabric are then joined to form a continuous belt. The extended end of the batt is overlapped upon its opposite end and the overlapping batt ends are cut across the width of the fabric such that the opposing batt ends are configured to complement and abut each other. Each of the complementary batt ends is combed for a length equal to at least the thickness of the batt such that the fiber dispersion of the batt material is decreased and the ends of the batt are lengthened. The combed batt ends are overlapped and needled together and to the base fabric such that the batt material of each end of the batt is interdispersed with each other and the resultant material has essentially the same uniform internal construction, density, thickness and surface texture as the remainder of the fiber batt.
