ニフォミティが低下するという問題があった。(Problems to be Solved by the Invention) By the way, the cutting edge of the belt-shaped member is not always straight, and for example, the cutting edge may be curved due to the influence of the embedded state of the steel cord or other reinforcing cord. ,
Where it may be wavy, any of the conventional clamping and straightening devices, there is no way to correct such unevenness such as curved state, wavy state, in the straightening device,
When the band-shaped member is wound around a forming drum, the imaginary approximation straight line considering the unevenness of the uneven cutting edge can be slightly approximated to the reference straight line. The amount of overlap with the end portion cannot be made uniform in the width direction of the molding drum, and in the butt joining, the leading edge and the trailing edge of the band-shaped member are tightly spaced over the entire width of the molding drum. However, there is a problem that the uniformity of the tire is reduced.

との間に挟持する。(Operation) When the edge position correcting device corrects, for example, the front edge position of the band-shaped member, the cut front edge has a wavy contour as shown by a thin line in FIG. 6 (a). And the approximate value line XX of the waveform contour is inclined by an angle θ with respect to a required reference straight line YY, in other words, a line segment orthogonal to the length direction of the belt-shaped member a. First, in a state where the extending direction of the base plate is in a position substantially parallel to the approximate straight line XX, the tip of the band-shaped member a is pressed onto the receiving table with the pressing member by the operation of the lifting frame driving means. Then, the portion of the belt-shaped member a on the tip side from the pressing position is bent upward by the action of a bent body projecting upward from the receiving table, and the bent tip portion is
Contact the surface of each slide plate with the clamp pawl open, then close the clamp pawl,
The distal end portion of the belt-shaped member a is sandwiched between the clamp claw and a slide plate whose surface has been subjected to edging over the entire width thereof.

から太線位置に修正する。After that, while the folded body is lowered, the base plate is lifted to some extent together with the leading end of the band-shaped member a by the re-activation of the lifting frame driving means, and the base plate is rotated by its rotation driving means. By rotating the approximate straight line XX to a position where the approximate straight line XX coincides with the reference straight line XY around the center position in the length direction, a substantial match between the approximate straight line XX and the reference straight line YY is determined. This corrects the position of the cutting edge from the thin line position to the thick line position in the figure.

After sufficiently approaching that of −Y, in order to correct the waving phenomenon of the cutting tip edge, first, the lower surface of the holding member is moved a predetermined distance l from the upper surface of the band-shaped member a on the receiving stand by the lifting frame driving means. And then the base plate and clamp mechanism are
By lowering only the holding member, the band member a is re-pressed by the holding member. At this time, the cutting leading edge is positioned as shown in FIG.

The portions corresponding to the slide plates No. 2 to No. 4 are lowered together with the slide plates whose surfaces have been subjected to the edging treatment by the downward displacement of the slide plates over the distance l, whereby the protruding cutting edge portions Is displaced rearward by the distance l, while maintaining the cutting edge position corresponding to the other slide plate in the same position,
As shown by the thick line in FIG. 6 (b),
It is brought to a substantially uniform position over the entire width of the band-shaped member a.

せることができる。By winding the band-shaped member around the forming drum in a state where the cutting tip edge position is corrected as described above, more preferably, the cutting edge position of the band-shaped member is also corrected in the same manner as described above. Thereby, the leading end portion and the trailing end portion of the belt-shaped member can be substantially uniformly overlapped in the width direction, or the leading edge and the trailing edge of the belt-shaped member can be sufficiently butted against each other.
