yarn has been lost in the lower fabric of the same part of the pattern however the same amount of pile tufts and tufts are maintained in the lower part of the pattern in the lower fabric an entire pile tuft two tufts of the second pile warp yarn has been lost whereas in the upper fabric of the same part of the pattern all pile tufts and tufts remain this means that in case the correction lift plans would have been applied to a part of the card design in which in the warp direction two or several single colour lines are occurring successively one line of a certain colour followed by a line of a different colour possibly again followed by a line of a different colour here at least one colour line would disappear in one of the fabrics which is unacceptable with respect to the design aimed at during the weaving process therefore normally the processing programme of the processing software will not apply these correction lift plans in cases in which a certain colour should disappear in one of the two fabrics after the correction lift plans having been applied so that a mixed contour will definitely not occur during the weaving process it is indeed possible to avoid such an imperfection by adapting the.
