部分が多くなる。そこで、実公平３−５６３５２号公報
に示されるような伸展装置が提案されている。By the way, since the length of the upper side and the lower side of the laminated glass for automobiles are different, if the intermediate film for joining the laminated glass is cut out from the linear belt-shaped resin sheet, there will be many wasted portions. Therefore, an extension device as disclosed in Japanese Utility Model Publication No. 3-56352 has been proposed.

As shown in FIG. 4B, which is a side view, the heating roll 10
Of the upper and lower sides of the sheet, the belt-shaped resin sheet 102 heated by contacting 0 is wound around the cone drum 101, and the wound belt-shaped resin sheet 102 is cooled by the cooling air jetted from the cooling box 103. One is relatively extended with respect to the other to be curved and drawn out, and this is cut into a predetermined size to form an intermediate film having a shape matching the shape of the laminated glass.

を自動化することができない。As described above, when the belt-shaped resin sheet is brought into contact with the cone drum to extend it,
When the cooling air is uniformly applied, the widthwise end portions of the strip-shaped resin sheet are more easily cooled than the central portion. As a result, the contraction speed is different between the end portion in the width direction and the central portion, and wrinkles 104 occur at the end portion in the width direction. If wrinkles occur along the widthwise ends, it is impossible to automate processes such as transportation, cutting, loading, and sticking.

形される。In the figure, reference numeral 1 denotes a cone drum, and the belt-shaped resin sheet 2 is stretched around the surface of the cone drum 1 by winding the belt-shaped resin sheet 2 in a heated state for about a half turn, and the belt-shaped resin sheet 2 is extended to one side. It is shaped like a fan whose sides are longer than the other side.

０の位置をロックする。Each chamber 6 has nine cooling air jet nozzles 7 arranged in two rows on the lower surface, and an opening 9 connected to the air introduction duct 8 is formed on the upper surface. The opening area of this opening 9 is determined by a slide gate 10. I am trying to adjust it. That is, the slide gate 10 is attached to the tip of the rod 11, and the knob 12 is attached to the rear end of the rod 11 extending outside the box portion 4.
The opening area is adjusted by sliding the sliding gate 1 and the uneven portion on the lower surface of the knob 12 is engaged with the rack 13 mounted on the upper surface of the box portion 4 to slide the slide gate 1.
Lock the 0 position.

一に冷却される。As a result, the amount of cooling air blown from the chamber near the end of the belt-shaped resin sheet 2 in the width direction is smaller than the amount of cooling air blown from the chamber near the center. On the other hand, since the portion of the strip-shaped resin sheet 2 near the end in the width direction is easily cooled from the beginning, these are offset and the strip-shaped resin sheet is cooled uniformly.
