Abstract:
Electrical control apparatus, for the output of textile pattern data to a plurality of groups of mechanical actuation elements for actuating thread guidance means of a textile machine, comprising:a plurality of serial-parallel converters each of which is connected to at least one of said groups of mechanical actuation elements, wherein each of said serial-parallel converters is configured to accept, for each connected group of mechanical actuation elements, at least one pattern data block from the textile pattern data;a serial data bus to which the serial-parallel converters are sequentially connected;an electronic processing unit, having a first connection to said data bus, and which in transmission cycles forms, from the textile pattern data, pattern data chains containing pattern data blocks in such a way that one pattern data chain per transmission cycle contains pattern data blocks for driving one mechanical actuation element in each of said groups, and in said transmission cycles, said electronic processing unit inserts the pattern data chains into the serial data bus so that at the end of each transmission cycle at least one pattern data block from the pattern data chain is contained in each serial-parallel converter, wherein at the end of each transmission cycle said electronic processing unit outputs a central release signal; anda plurality of assignment means, each of which is connected to one of said groups of mechanical actuation elements, each of which is connected to a serial-parallel converter, and each of which is configured to receive a central release signal from said electronic processing unit, wherein upon receipt of a central release signal said plurality of assignment means causes the serial-parallel converters synchronously to output the pattern data block currently contained in each serial-parallel converter to an actuation element of the at least one group of mechanical actuation elements connected to that serial-parallel converter.
