Abstract (en)
[origin: US4311916A] A travelling scanning apparatus for successively checking the working conditions at the spinning position of a ring spinning machine is enabled, in order to determine whether a yarn breakage has occurred at a spinning position, and, in the affirmative case, whether there prevails a danger of damage due to lap-up formation on a roll of the drafting arrangement. Using a yarn feeler first the presence of a normally spun yarn is detected. If no yarn is present, the broken yarn suction nozzle, which is used for eliminating the fibres not spun in, is lowered from its normal working position into a scanning position, and an optimum fibre stream is obtained between the delivery rolls of the drafting arrangement and the lowered nozzle for scanning using a second feeler. In case of non-presence of this fibre stream, that is in case possible lap-up formation, a roving supply interrupting device is activated and the roving supply to the drafting arrangement is interrupted.
