Abstract
An automatic sewing machine for forming a desired pattern on a workpiece by means of varying the position of a workholder for holding the workpiece in relation to a needle which is vertically reciprocated due to pattern data stored in advance in memory means. A sewing machine of this type is provided with a manual input device for setting up a numerical limit indicating an allowably movable sphere of the workholder without impacting or interfering with the needle and a controller for calculating a numerical result indicating the movement amount of the workholder in relation to the needle during the pattern forming operation based on the pattern data prior to the pattern forming operation. The controller makes a comparison of the calculated numerical result with the numerical limit set by the manual input means, and generates a signal for warning the operator of the exceeding, if so being the case, of the calculated numerical result over the above-mentioned set numerical limit.
