Abstract
Abstract Method and apparatus for automatically removing filled bobbins from spindles spaced apart along the length of a spinning machine. The bobbin handling apparatus includes a carriage that moves along the length of the spinning machine and in timed sequence removes a plurality of filled bobbins from their spindles, transfers the filled bobbins to a rack or bobbin transporter, picks up a plurality of empty bobbins, transfers the empty bobbins to the previously doffed spindles, and then travels to the next position, where the process is repeated. The carriage includes guide means to position precisely the rack with respect to the spindles.
