Abstract
An industrial sewing machine having a main shaft which can be driven by an electric motor drive, a positioner disposed on the main shaft, a regulating and control system controlling the electric motor drive, an operating and display system, and an interface system producing the connection between the operating and display system on the one hand and the regulating and control system on the other. Such an industrial sewing machine is to be configured such that great freedom from electrical interference will be achieved in spite of the individual connection of additional unfiltered electrical components. For this purpose two lines are provided for each component for carrying signals back and forth among any number of connected components, and the output of each of the connected components has a driver stage with a system for inverting the signal that is to be transmitted, an inverted signal being transmitted over the one line and a non-inverted signal over the other, and the input of each of the connected components includes a difference detector to determine the difference between the two arriving signals.
