摘要

A method and apparatus for piecing a sliver and at least one of a leading yarn and a bobbin yarn. A nozzle member and a spindle member having a hollow spindle are provided. A relative spacing is established between the nozzle member and the spindle member. At least one of a leading yarn and a bobbin yarn is inserted into the hollow spindle of the spindle member relatively spaced from the nozzle member. The relative spacing between the spindle member and the nozzle member is decreased, so that the spindle member and the nozzle member mutually form an air chamber. A compressed air flow is directed into the air chamber. Sliver is supplied to at least one of the leading yarn and the bobbin yarn, and the sliver and at least one of the leading yarn and the bobbin yarn are pieced together.
