PURPOSE:To automate the thread edge nipping work by providing an arm which is set under the thread edge caught by a holding device and turns around the taken-up material and retreats, catching the thread edge, and interposes the thread edge under the thread which is taken up already. CONSTITUTION:A top 50 which completes taking-up operation is fitted onto a transport shaft 12, and the sliver end is caught by the chuck part 16 of a holding device 3 which is advanced, and then retreated. Then, the transfer shaft 12 is turned towards a thread edge processing part 3. Then, a rolling-in arm 32 advances inside in comparison with the sliver end, and when a hook 40 reaches the position of the sliver end, the rolling-in arm 32 revolves several times on the periphery of the top 50 in the opposite direction to the direction of thread winding, and the arm 32 is set under several pieces of thread materials which are wound already. Then, air is supplied into the thin pipe of the arm 32, and the hook 40 is opened outwardly, and then the arm 32 retreats, and the sliver end is caught by the hook, and set under the thread material, and then sliver end is fixed under several pieces of threads.
