(57) The present invention allows sliver ends to be stably pieced together so that the
resulting slivers exhibit a required strength. A sliver piecing device includes a
pair of piecing members 1, 1' that slide alternately with ends S11, S11' of a pair
of slivers S, S' sandwiched between the piecing members 1, 1' to rub and piece the
ends together. The piecing members 1, 1' both comprise respective entanglement preventing
groove portions 10, 10' preventing entanglement during rubbing, on respective surfaces
1a, 1a' between which the sliver ends S11, S11' are sandwiched. Each of the entanglement
preventing groove portions 10, 10' is formed in a central portion of the sandwiching
surface 1a, 1a' so as to extend in a sliding direction 1b, 1b' (Fig. 12).
