Abstract
Abstract The disclosure is of a seam construction for joining the ends of woven forming wire wet felts and dryer felt materials. The forming wires wet felts, and dryer felts are used on papermaking machines in the manufacture of paper, paperboard and the like. The seam comprises a plurality of metal and/or plastic eyepins, having body crimps adapted to permit interweaving of the pins with the crosswise yarns of the forming wire wet felt or dryer felt material ends. The pins are so interwoven and are spaced to interleaf with the pins of the opposite end. A seam pin is threaded through the eyes of the eyepins to join the ends of the forming wire, wet felt or dryer felt material together.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
144 words
A seam construction joining together the ends of a forming wire press fabric or felt or a dryer felt, which comprises; the ends to be joined; a plurality of eyepins having sinuously curved bodies, replacing terminal portions of the lengthwise yarns in each of said ends, said eyepins being anchored in the ends by an interweaving of the sinuous bodies with the crosswise yarns in the ends, the curves of the sinuous body mating with the crimp of the weave of said crosswise yarns, the eyes of said eyepins projecting from each end wherein the eyepin is anchored, said eyepins being positioned in the ends so that when the ends are brought together, the eyes of one end interleaf with the eyes of the other end; and a joinder pin passing through the interleafed eyes of said eyepins whereby said ends are joined together.
Claim 2
Dependent Claim
144 words
A seam construction joining together the ends of a forming wire press fabric or felt or a dryer felt, which comprises; the ends to be joined; a plurality of eyepins having sinuously curved bodies, replacing terminal portions of the lengthwise yarns in each of said ends, said eyepins being anchored in the ends by an interweaving of the sinuous bodies with the crosswise yarns in the ends, the curves of the sinuous body mating with the crimp of the weave of said crosswise yarns, the eyes of said eyepins projecting from each end wherein the eyepin is anchored, said eyepins being positioned in the ends so that when the ends are brought together, the eyes of one end interleaf with the eyes of the other end; and a joinder pin passing through the interleafed eyes of said eyepins whereby said ends are joined together.
