In the conventional method, as shown in FIG. 4, the short mold piece 3 is horizontally moved by a screw shaft 6 via a moving frame 4. In addition, the eccentric cam 16
is rotated by the drive device 12 via the drive shaft 8, the support frame 5 is tilted about the spherical centers of the spherical supports 10, 10', and the short side mold piece 3 is tilted.

量Ｔに演算し直して、該傾斜量Ｔを算出する。 The amount of inclination T of the short side mold piece 3 is determined by detecting the rotation angle θi of the eccentric cam 16 using a pulse transmitter 11 provided on the non-drive side of the drive device 12, and calculating the rotation angle θi using a computer (not shown). Accordingly, the inclination amount T of the short side mold piece 3 is recalculated to calculate the inclination amount T.

出す。 T=l 1 ×e/l 2 (1-cos θi) where T: Amount of inclination of the short side mold piece 3 θi: Rotation angle of the drive shaft 8 of the eccentric cam 16 l 1 : Height of the short side mold piece 3 ( (shown in FIG. 4) l 2 : Distance from the spherical center of the spherical support seat 10 to the point of contact between the eccentric cam 16 and the support frame 5 (shown in FIG. 4) e: Eccentricity of the eccentric cam 16 (as shown in FIG. 4) Problems to be Solved) The above-mentioned conventional technology has the following problems. In FIG. 4, when adjusting the inclination of the short side mold piece 3 by rotating the eccentric cam 16, the rotation angle θi of the drive shaft 8 is changed from 0 to 0 as shown in FIG.
It is rotated within a range of πrad, but,
Since the rotation range of the drive shaft 8 is not regulated, the drive shaft 8 often rotates beyond that range.
When the inclination amount T of the short side mold piece 3 deviates from the regulated inclination amount T and the previous inclination direction changes to the opposite direction, that is, when the rotation angle θi of the drive shaft 8 exceeds πrad, the inclination amount T becomes On the contrary, the rotation angle θi starts to decrease.
When it becomes smaller than 0 rad, the amount of inclination T starts to increase.

This was causing operational problems such as:
