Abstract

A process for determining the arrangement and step sequence of heald shafts of a heald loom for weaving a fabric including a backing fabric having a fabric pattern and an ornamental design. The ornamental design of the fabric is plotted and/or displayed by means of a computer. Alternatively, the combined appearance of the ornamental design and the fabric pattern may be plotted and/or displayed. Next, the number of heald shafts necessary for weaving the ornamental design or the combined appearance is determined. Heald shaft arrangements that are conventionally used and/or available which will weave a fabric design similar to the ornamental design or the combination designed are plotted and compared with the heald shafts determined for weaving the ornamental design or the combination design. The step sequence of the individual heald shafts in the heald loom from the assigned heald shaft arrangement is determined. Finally, the resultant fabric design with the determined heald shaft arrangement and step sequence is displayed and/or woven on an output unit.
