The angle member W is conveyed from the previous step on the conveyor 8 with one side thereof standing upright and stopped at a predetermined position where the corner portion comes into contact with the conveyor flange 8a, and then the rotating member 1 rotates. Then, when the first mounting portion 6 of the one protruding portion 5 of the rotary member 1 is slightly past the horizontal position in FIG. 1, the angle member W is received by the mounting portion 6 and mounted. Next, the angle member W slides on the first mounting portion 6 by its own weight as the rotating member 1 further rotates, and the corner portion thereof comes into contact with the first step portion 9 (FIG. 2).

Next, the angle member W is further rotated by the rotating member 1 so that one side of the angle member W falls down on the second mounting portion 7,
Moreover, it slides on the first mounting portion 7 by its own weight, and the tip portion thereof comes into contact with the second step portion 10 (FIG. 3).

Next, the angle member W is further rotated by the rotating member 1 so that the second step portion 10 as shown by a chain line in FIG.
It swings around the tip of one side that abuts against the fulcrum and drops onto the pedestal 11 (Fig. 4).

As described above, the angle member W is rotated by 135 ° from the conveyor 8 on one side in the direction of rotation to the pedestal 11 on the other side by one operation of the rotating member 1 to change its posture.

The angle member W whose posture has been changed is then extruded by the extruding member and transferred onto the conveyor 13,
It will be transported to the subsequent process.

Such a change in the posture of the angle member W is performed three times, which is the number of the protruding portions 5, per one rotation of the rotating member 1.
