PURPOSE:To facilitate hold of works and to enable holding a plurality of works by fitting adsorbing members at points of work holders provided on feed bars and equipping operating devices for vertically reciprocating work holders. CONSTITUTION:Feed bars 3 are provided on both sides of die lines where dies 2 are arranged at an equal interval of a plurality of dies so that the feed bars can make a three dimensional motion to the die lines. The work holder 10 corresponding to each die 2 is provided on both feed bars 3 and works W are transferred by the motion of the feed bars 3 in sequence onto each adjacent die 2 and worked. At this time, the adsorbing member 15 to adsorb the work W is provided on the point part of each work holder and the operating device 11 for the holder to raise and lower the work holder 10 is fitted to the feed bar 3. Hereby, the motion of steps of (a), (b) of the work holder 10 is added to the three dimensional motion of steps ((1)-(6)) of the feed bar 3 to make it possible to hold and release the work W by the adsorbing member 15 and to work a plurality of works W with the same die 2. |
