摘要
The process for replacing an empty roving bobbin with a full roving bobbin in a spinning machine, particularly in a ring spinning machine, in a dispensing position by an automatic roving bobbin changing device comprises taking the full roving bobbin from a storage location and putting the full roving bobbin in place of the empty roving bobbin. The full roving bobbin associated with the dispensing position is taken from one of a plurality of stand-by positions in the storage location. To provide a more automatic operation the process further comprises testing whether the full roving bobbin is present in one of the stand-by positions adjacent the dispensing position before beginning the exchange and when the absence of the full roving bobbin is indicated inducing a relative motion between the roving bobbin changing device and the stand- by positions until the roving bobbin changing device stands adjacent to one of the stand-by positions having a full roving bobbin. An apparatus for performing the process of our invention is also provided.
