Method and apparatus for piecing a sliver and at least one of a leading yarn and a bobbin yarn

A yarn piecing method utilizing a turning air flow for piecing a sliver and at least one of a leading yarn and a bobbin yarn on a take-up side, comprising:

• providing a nozzle member having a surface and a spindle member having a surface and a hollow spindle,
• establishing a relative spacing between the nozzle member and the spindle member,
• inserting at least one of a leading yarn and a bobbin yarn on a take-up side into the hollow spindle of the spindle member relatively spaced from the nozzle member,
• decreasing the relative spacing between the spindle member and the nozzle member so that at least a portion of the surface of the spindle member and at least a portion of the surface of the nozzle member mutually form an air chamber,
• generating a compressed air flow,
• directing the compressed air flow into the air chamber, and
• supplying sliver to at least one of the leading yarn and the bobbin yarn,
• whereby the sliver and at least one of the leading yarn and the bobbin yarn are pieced together.
