Lose. The rotating plate 12 is initially disposed at a set angle α in a state where one side and the other side are in elastic contact with the first pressing member 28 and the second pressing member 29, respectively.

Due to this installation structure, the pressing member 27 elastically presses the pivoting plate 12 at a set pressure based on the support 21 or the pivoting plate support 23. According to the elastic force of the coil spring constituting the pressing member 27, the pressing force for pressing the rotating plate 12 according to the material, thickness, and length of the coil spring can be varied and adjusted.

The first pressing member 28 is installed to elastically press the rotating plate 12 in the forward direction toward the middle portion BC in the width direction of the belt conveyor 2. The rotating plate 12 is elastically supported in the forward direction by the first pressing member 28, so that the installation form inclined toward the middle portion BC in the width direction of the belt conveyor 2 can be maintained. When the raw material (3) passes between the pair of rotating plates (12), the rotating plate (12) is pushed against the raw material (3) by being elastically supported in the forward direction by the first pressing member (28) to apply a pressing force in the reverse direction. While receiving, it is rotated in the reverse direction by the open rotation angle (β).

The second pressing member 29 is installed to elastically press the rotating plate 12 in the reverse direction toward the width edge portion of the belt conveyor 2. When the transport amount of the raw material 3 is rapidly reduced or a section in which the loading of the raw material 3 does not occur occurs, the pivoting plate 12 is pushed against the first pressing member 28 and rapidly rotated in the forward direction, thereby extending the intermediate length.
