PURPOSE:To open a stock tube free as well as to aim at the simplification of an auxiliary device in structure by means of a single driving source which rotates a driving plate. CONSTITUTION:Movement in an auxiliary guide 42 and open operation in a stock tube 24 are performed by a single driving source used for rotating a driving plate which takes a bar work out of a stock rack 10 by one. In addition, in order to operate a magazine 14 in an orderly manner, plural rollers are installed in the circumferential part of a stock reel of the magazine 14, while such a method that one side of halved stock tubes 24 is made to act on a direction of being normally closed is adopted whereby such a risk that is interlocked in leaving one half part of these halved stock tubes 14 opened intact is brought to nothing and, what is more, such a cause that said one half part of these stock tubes 24 openes and colloides with a guide inner circumferential surface, causing generation of a noise, is eliminated. |
