Abstract
A device for exchanging data between a plurality of rail-supported movable automatic manipulating units for operating a plurality of textile machines with multiple workstations and a common central unit comprises a rail system and a lead system connected to the rail system. The lead system comprises at least two and at most three data-transmitting leads that serve exclusively for data transmission in addition to supply leads for supplying electric current to the automatic manipulating units. The data-transmitting leads form a ring conduit to which the sending and receiving devices of the central unit as well as the sending and receiving devices of the automatic manipulating units are connected via additional sliding contacts. Data are sent from the sending and receiving devices in the form of impulses with a predetermined duration at predetermined intervals and each data impulse is simultaneously guided to two leads with opposite polarity. The sending and receiving devices are furthermore designed such that only such impulses are processed which are simultaneously received via both data-transmitting leads and which have a predetermined minimal signal strength.
