In a control equipment for an industrial sewing machine, it being possible, via switchgears such as switches, probes, sensors or the like, to switch on or off functions and connection states, by a certain voltage level being applied to an input circuit of the control, the input circuit generating an output signal, it is provided that upon the application of varying input voltages U, the output voltages Ugenerated are the same in each case.

Control equipment for an industrial sewing machine

In a position indicating device, especially for an industrial sewing machine, with a slotted wheel (3) and a first track (6) of slots (4) having, e.g., 512 slots (4), to permit a null-point synchronization over a relatively small range of rotational angles, and the establishment of definite angular positions, a second track (8) with slots (7) of various widths is provided. The first track (6) of slots (4) is associated with two light barrier arrangements comprising emitters (11a, 11b), receivers (12a, 12b), and masks (13a, 13b) while the second track (8) is associated with one light barrier arrangement. Evaluating systems are connected to the receivers (12) so that, on the basis of the number of slots (4) of the first track (6), the size of the slots (7) passing in each case and corresponding approximately to a multiple of the slot width may be determined through evaluating systems (14, 28) connected to the output, and in this manner to define the rotary angle position.
