ABSTRACT:
A method for digitally sensing and storing a sewing pattern for an industrial sewing machine. To make the sensing process fast and free of error, the invention provides that, starting from a null position of the driving step motors, the fabric carrier is moved under program control in such a fashion that a sewing pattern, disposed on the carrier for the material to be sewn, is scanned 2-dimensionally, the incremental x and y positional data of each step motor always being stored, when the sensor detects a bright-dark contrast on the sewing pattern. Further, for manual input or for making corrections, a device is provided, which is distinguished by a rotary device for setting the desired directional angle of the same pattern. This rotary device can be activated in a direction perpendicular to the rotation-adjustment plane, counter to a reset spring, to initiate a contact.
