3、 or “fall on the left” position, where the card is placed above the left of the weaving machine. The expression “interlaced” harness is used when the cards are in a lateral position, while in cases where the cards are in an ax- ial position, the harness cord guide is described as being “open”. If th
4、e equipment operates on the basis of this “open” harness, the following two systems for the positioning of the cards are possible: a) system 1 : Card position in front-left-right; b) system 2: Card position at the back-left-right. In these systems, the following elements correspond to the first warp
