Abstract
Piecing method of a spinning machine whereby, after holding outside a twist device both a leading yarn ejected from the sliver guide entrance of a twist device in a stationary state and a sliver delivered by a re-operated draft device, the twist device is operated, the sliver supplied to the twist device and the fibers comprising the sliver are entangled in the leading yarn pulled from the twist device. The success rate of yarn piecing may be improved without detailed adjustment of the pulling timing of the leading yarn guided into the twist device and the supply timing of the sliver supplied to the twist device.
