ABSTRACT:
A papermaking wire of double layered fabric, consisting of a set of warp threads, yarns in machine direction, and a set of weft threads on the running side of the wire, yarns in cross machine direction, as well as a set of weft threads on the paper side of the wire, the last one consisting of at least two groups of weft threads differing from one another with respect to the outwardly located length of floatings. In order to avoid an unacceptable decrease of the stability of the wire and avoid markings in the paper as well as an essential reduction of drainage of the wire, if the number of cross threads on the paper side is increased, the wire is configurated such that it includes three groups of cross threads A, B, C on the paper side. Within one weave pattern each warp thread is transversing three weft threads succeeding one another on the paper side and running thereafter between the weft threads on the paper side and on the running side interlacing at least one weft thread on the running side. Thereafter, the warp thread crosses below three cross threads, succeeding one another on the paper side and thereafter crossing over three crossthreads succeeding one another on the paper side.
