Monitoring of core mounting for a roving frame

摘要

A roving frame has a flyer region into which the suspension carriage trains are moved past a device for monitoring the presence or absence of cores or bobbins on the hangers. An error signal is transmitted in the case of an error and correction is effected when the suspension carriage train is in the flyer region. The suspension carriage train is then moved back past the sensors and either on this backward movement or the next forward movement, the functional correctness or poor mounting is again measured. Correction is effected in each case in the flyer region where the hangers are more readily accessible.
