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.Field of SearchEdges and seams | |
