ABSTRACT:
A method and device for regulating the transport of material in a sewing or embroidery machine (1) that uses information from a position or movement sensor (33) located underneath the throat plate (21). The controls for the sewing machine (1) calculate deviations of the actual feeding increments of the article to be sewn from the corresponding target values from the periodically read sensor signals. With this information, the feeding increments are regulated in such a way that the deviations are cancelled out by averaging.
