PURPOSE: To tilt a panel by a required angle to satisfy a requirement of a press by setting the center of curvature of a guide surface near the center position in the line direction of panels mounted on panel supporting tools and near the center position in the height direction.

CONSTITUTION: When the panel 4 is mounted on the panel supporting tools 9, a pinion 14 is driven rotatively by a motor, a sector gear 15 turns, each wheel 8 travels along the guide surface 2a of each supporting frame 2. As a panel receiving base 10 is slantingly moved by a required angle along each guide surface 2a, the panel 4, too, on the panel supporting tool 9 tilts. At this time, since the center 0 of curvature of each guide surface 2a agrees with the center position in the line direction X of the panel 4 and the center position in the height direction, the center position of the panel 4 sent by a feed bar always at the same pitch to the downstream side does not shift to the line direction. In this way, the panel 4 tilted by a required angle and changed in posture is mounted surely by the feed bar on a lower die at the succeeding press station.
