PURPOSE:To ensure that no crease occurs in a width direction end part when extending a band-shaped resin sheet. CONSTITUTION:When extending a band-shaped resin sheet 21, a position for the slide gate 10 of each chamber 6 is adjusted, and an opening area is smaller in a chamber near the width direction end of the band-shaped resin sheet 2, and becomes gradually larger toward a center chamber. Thus the volume of a cooling air spewing from a chamber near the end of the width direction of the tape-like resin sheet 2 is smaller than the volume of a cooling air ejected from a chamber near the center. On the other hand, the part near the end of the width direction of the band-shaped resin sheet 2 is originally apt to be easily cooled, so that this trend is offset to cause the band-shaped resin sheet to be cooled uniformly. |
