Abstract
On a piecing method of a spinning machine which, after cutting a sliver between normally rotating draft rollers and stationary draft rollers, inserts a leading yarn into the spindle of a twist device and carries out piecing by the restarting of the draft rollers, restarting of the twist device and running of the leading yarn, approximately all the fibers comprising the tapered tip of the cut sliver form the joint part by being entangled in the leading yarn. As almost all of the fibers comprising the tapered tip of the cut sliver contribute to the joint part, the success rate of piecing is increased and a stronger joint part may be formed.
