An automatic yarn piecing apparatus for use with an spindleless spinning machine of the type having a plurality of spinning units each of which spins fiber materials into a yarn and deliver the thus-formed yarn to be taken up on a bobbin. The apparatus travels along the front face of the spinning machine and stops at the position of a particular spinning unit wherein yarn breakage has occurred, to automatically piece the broken yarn by the cooperation of various means in such a manner that the broken yarn is withdrawn from the yarn package on the bobbin, gripped and cut to form a new cut end of the yarn while simultaneously removing the snarl from the yarn end, and then the cut end of the yarn is introduced into the rotary chamber of the spinning unit through the delivery outlet thereof to effect piecing of the yarn.
