Jacquard machine, face-to-face weaving machine comprising at least one jacquard machine, and method of setting up a jacquard machine

Jacquard machine, comprising:

• a plurality of yarn moving elements and in association with each yarn moving element a yarn moving mechanism having an output cord connected to the yarn moving element,
• a plurality of setting bars extending substantially in a first direction corresponding to a weft direction and positioned adjacent to each other substantially in a second direction corresponding to a warp direction, each setting bar having two longitudinal end regions and a cooperation region arranged between the longitudinal end regions for the cooperation with a plurality of yarn moving mechanisms,
• a plurality of position adjustment bars extending substantially in the second direction, wherein in each one of the two longitudinal end regions of the setting bars two position adjustment bars are provided adjacent to each other,
• a plurality of connecting means for connecting the setting bars to the position adjustment bars, wherein in each longitudinal end region of each setting bar one connecting means is provided such as to be connectable to either one of the two position adjustment bars arranged in a respective one of the longitudinal end regions of the setting bars.

Method of setting up a jacquard machine:

• a) defining first sub-groups of yarn moving elements provided for the cooperation with pile warp yarns to be incorporated in a top fabric of a face-to-face fabric as dead piles and defining second sub-groups of yarn moving elements provided for the cooperation with pile warp yarns to be incorporated in a bottom fabric of the face-to-face fabric as dead piles, such that there is an alternating arrangement of the first and second sub-groups in a direction substantially corresponding to a warp direction,
• b) in association with the alternating arrangement of the first and second sub-groups of yarn moving elements providing an alternating arrangement of first and second sub-groups of setting bars by connecting the setting bars of the first sub-groups of setting bars in each one of their two longitudinal end regions to one of the two position adjustment bars provided in each one of the two longitudinal end regions of the setting bars and connecting the setting bars of the second sub-groups of setting bars in each one of their two longitudinal end regions to the other one of the two position adjustment bars provided in each one of the two longitudinal end regions of the setting bars, wherein at least one sub-group of setting bars comprises a plurality of setting bars positioned adjacent to each other in a direction substantially corresponding to the warp direction,
• c) connecting yarn moving mechanisms associated with the yarn moving elements of the first sub-groups of yarn moving elements to the setting bars of first sub-groups of setting bars and connecting yarn moving mechanisms associated with the yarn moving elements of the second sub-groups of yarn moving elements to the setting bars of the second sub-groups of setting bars.
