PURPOSE:To carry an iron plate to a working machine such as a press, etc. along any curve by providing a pair of magnet rolls on a table that rotates at a specified angle, and giving a difference in peripheral speed to these rolls. CONSTITUTION:A pair of iron plate feeding devices 11, 11 are installed against a press 33 so that the distance between the center B of rotation of a rotary table 21 and the center axis Y of the press becomes L. The rotary table 21 is set at a specified angle, and two rolls 25, 26 are rotated at driving pulse number that makes the peripheral speed of the magnet 25 proportional to the distance D1 and the peripheral speed of the magnet roll 26 proportional to the distance D2, respectively. A rectangular iron plate 2 placed on a nondirectional roll 14 is magnetically attracted by the two rolls 25, 26, and, by their rotation, sent into the press 33 along circular arcs having radii D1, D2. The driving pulse to pulse motors 29, 30 is supplied intermittently so that the iron plate 2 is carried at a specified pitch. |
