Abstract

A method and apparatus for transmitting data within a textile machine of the type having a central main power supply and many identical work or spinning stations is disclosed with the data being for controlling operational at independently operable work stations, particularly in open-end bobbin winding machines. A separate power supply is included for providing a buffer voltage for use at memories within the individual spinning station central units, with the power supply output being DC voltage at a predetermined level. The DC buffer voltage signal is modulated with the data for transmission to the work station, transmitted to the work station and demodulated thereat for use.
