<p>Sewing operations are automated, at least partially, using a controllable sewing machine. In an initial recordal phase for the sewing operation to be effected, there are put into memory the instantaneous values of three sensed parameters, i.e. the time, the position of a sewing speed control element and the length of the sewing, at each time the position of the speed control element changes under the action of the operator. Then, in a reproduction phase, the time is detected in continuous fashion, as is the distance sewn, and the position of the speed control element is changed at each moment for which the time detected is equal to a time recorded, or for which the length sewn is equal to the length recorded. The system is of value in the clothing industry.</p> |
