is weighted to maintain the proper tension in accordance with accepted jacquard techniques with reference to fig4 and 5 it can be seen from a comparison of the two figures that the yarn designations and their positions have been reversed or inverted accordingly in fig5 the lower right hand position is designated 16 as opposed to its previous designation as 1 and will receive the yarn 14 16 as described above the yarn 14 16 continues through the ribbon control bracket 80 and is weighted as can be seen from a comparison of fig4 and 5 the respective yarns 14 1 through 14 16 occupy the same relative position in their respective ribbon 14 and plate 32 it is at this point that the lacing of the harness cords 6 becomes relevant the respective harness cord 6 from each side of the jacquard machine is laced with the respective tying yarn of ribbon 14 in accordance with the weave repeat pattern in our example of an eight shed positions 1 through 8 on each side of the jacquard machine 2 would be connected to the respective positions 1 through 8 on the respective plate 32 the second repeat 9 through 16 would be connected in a like manner by reference to fig5 and 6 the result of operating the jacquard machine under the above described control is illustrated as can be seen in these figures the ribbon 14 is manipulated or shedded in the mirror image of itself as a result of this mirror image shedding the proper tied yarn 16 is sequentially released from the tying yarns of the ribbon 14 and is made available for interweaving with reference to fig1 the preferred embodiment includes a pulsed air or pressure.
