Abstract
Method and device for safe operation of an automatic sewing machine having a programmable computer controlling a seam contour, at which a contoured workpiece clamp is automatically identified and compared with the sewing contour prior to the start of the sewing operation. The method also may include a further subroutine for automatically positioning the controlled seam contour with respect to the workpiece clamp so as to eliminate an accumulation of errors resulting in damaging of the automatic sewing machine. According to this invention a sewing head is provided with a sensor, which is moved along a distance limited by a firm reference point and a trigger point arranged at the workpiece clamp, where the detected distance corresponds to the profile of the workpiece clamp.
