Abstract

Apparatus and a method for converting patterns for weaving into stored information by scanning according to a scanning raster the pattern and determining the number of steps per stitch of the scanning raster by using the quotient of the dimensions of the scanned pattern divided by the number of stitches in the same direction and wherein such quotient is used such that at equality or upon a known deviation from a prescribed fraction of a step a signal is generated which indicates the beginning of the next stitch and wherein a greater deviation than said prescribed one the signal is given after a further step has been accomplished.
