ABSTRACT:
A method and apparatus is provided for treating pieced places in yarn produced on open end spinning machines. The pieced places are treated by mechanically compacting the same during drawing off of the yarn from a spinning machine after a piecing operation. Various embodiments are disclosed for carrying out this mechanical compacting, including retractable fingers, rollers, and belts, which operate together to press the piece places and compact the same during drawing off of the yarn from the spinning assembly. In preferred embodiments, the apparatus for compacting the pieced places is carried on a mobile servicing device.
