Abstract
Difficulties are met with when contour-stitching patterns deposited on two-dimensional elastic fabrics because the originally printed or woven-in pattern is significantly warped already during printing or weaving and then during the clamping of the fabric in a clamping frame because of the fabric's elasticity. To make possible automatic contour-stitching, the invention proposes to feed the theroretical dimensional data of the pattern contours together with at least a few prominent sites into a memory of an electronic control for the automatic stitching machine and the actual dimensional data of at least those prominent sites are inputted by means of a computer in such a manner that the theoretical dimensional data are corrected relative to the actual positions of the pattern contours.
