  • Patent number: 6162518
    Abstract: The invention relates to a length of textile, especial as a basis for papmaking machine coverings, the length of textile containing structural threads (8, 9, 10, 11) and viewed width-wise being composed at least in part of several partial lengths (6, 7) which are located next to one another and which are bonded to one another on their edges (12, 13). The invention is characterized in that the partial lengths (6, 7) on their edges (12, 13) have projecting thread sections (14, 15) which fit into one another with overlapping, and that at least one connecting thread (16) is placed over the thread sections (14, 15) and is bonded to the thread sections (14, 15). The invention relates furthermore to a process for producing one such textile length.
