A position adjuster 41 for adjusting the position is provided. The position adjuster 41 includes a protruding plate (protruding member) 42 provided at an end of the support shaft 27, and holds the end of the protruding plate 42 from both upper and lower sides so as to be slidable in the horizontal direction. It comprises a pair of upper and lower bolts 44a and 44b screwed to the support 6 via 43a and 43b. By adjusting the screwing amounts of the bolts 44a and 44b, the support shaft 27 is rotated.

The portion can be located near the surface of the composite sheet.

When the motor 38 of the rocking device 31 is driven, the disk 40 connected thereto is rotated, and the rocking lever 36 having one end engaged with the pin 39 on the disk 40 is supported. The support shaft 27 swings about the shaft 32 and engages with the other end of the swing lever 36 in the horizontal direction. That is, since the reinforcing fiber part 4 is discharged while being swung horizontally from the reinforcing fiber part forming die 5, a composite sheet in which the wavy reinforcing fiber part 4 is laminated is formed. A composite sheet having enhanced strength in the vertical and horizontal directions can be manufactured without replacing the die 5 for use.

Therefore, even when the reinforcing fiber part forming die 55 is rotated by the position adjusting tool 121, the respective support shafts 83a and 83b on the rocking device 101 side are not rotated, and the blocks 81a and 81b are rocked. You can exercise.
In addition, as described above, the support shaft portion 83a on the swing device 101 side,
Although the 83b can be rotated with respect to each of the blocks 81a and 81b, a configuration may be adopted in which each of the support shafts 83a and 83b is integrally connected to each of the blocks 81a and 81b. In this case, in the connecting portion of each support shaft portion 83a, 83b to each swing lever 106a, 106b, each support shaft portion 83a, 83b is at a predetermined angle (position adjustment range of the discharge port).
For example, it is connected so as to have a gap so that it can rotate.

In the above configuration, the sheet resin supplied into the resin supply path 61 is fed into the lip path 75 through the gap path 59 and then pushed out to the sheet discharge port 66 side.

Thus, the vertical position of the linear portion discharge holes 82a and 82b can be changed. For example, when manufacturing a composite sheet used for an application in which a large load is applied to the surface, the positions of the bolts 126a and 126b are adjusted, and the linear portion discharge holes 82a and 82b are rotated upward. By doing so, the reinforcing fiber portion can be arranged near the surface of the composite sheet.

Each of the swinging devices 101a, 101b
When the motors 108a and 108b are driven, the disks 110a and 110b connected to the motors 108a and 108b are rotated, and one end of each swing lever 106 is engaged with the pins 109a and 109b on the disks 110a and 110b.
a and 106b are swung around the support shaft 102, and the respective shaft portions 8 are engaged with the other ends of the respective swing levers 106a and 106b.
3a and 83b swing horizontally.

That is, since the support shafts 83a and 83b can swing independently, each of the blocks 81
a and 81b can perform a rocking motion alternately and independently. Therefore, for example, as shown in FIG. 6, a composite sheet in which the reinforcing fiber portions 54 are arranged in a mesh pattern can be formed, and the strength of the composite sheet in the vertical and horizontal directions can be improved.

In the second embodiment, the cross sections of the linear discharge holes 82a and 82b formed in the blocks 81a and 81b of the molding die are circular. For example, FIGS. As shown in FIG.
The cross section of 2'a, 82'b may be formed in a semicircular shape.

In each of the above embodiments, when the rotation speed of the motors 38, 108 of the rocking devices 31, 101 is changed, the rocking speed of the reinforcing fiber portion forming dies 5, 55 can be changed. The number of wave irregularities per unit length can be changed. In addition, the disks 40, 1
By changing the positions of the pins 39, 109a, 109b on the 10a, 110b, the dies 5, 5,
5 can be changed, so that the amplitude of the wave can be changed. Therefore, according to various strength requirements,
A composite sheet in which the shape of the wave is changed can be formed.

In each of the above embodiments, the position adjusters 41 and 121 of the reinforcing fiber portion forming dies 5 and 55 are
A pair of upper and lower bolts 44a, 44b, 126a, 126b
By adjusting the screwing amount of the bolt 44,
a, 44b, 126a, 126b, the protruding plate 4
2 and 124, the support shafts 27, 83a, 83b
Is rotated, that is, the protruding plates 42, 124 may be swung by, for example, one bolt connected to the ends of the protruding plates 42, 124 instead of the upper and lower two bolts. Good.

As described above, according to the configuration of the first composite sheet forming die apparatus of the present invention, the reinforcing fiber part forming part which is supported in the sheet part forming die so as to be vertically rotatable. Since the die is provided, for example, when strength is required near the surface of the sheet, without replacing the die, it is possible to move the position of the linear portion discharge hole in the composite sheet upward, Therefore, it is possible to easily form a composite sheet in which the reinforcing fiber portions are arranged on the surface of the sheet.

Further, in the above configuration, since the swinging device for swinging the reinforcing fiber portion forming die in the horizontal direction is provided, the reinforcing fiber portion forming die is swung while the sheet resin is ejected. The fiber part can be discharged,
Therefore, the reinforcing fiber portion in the composite sheet can be formed into a corrugated shape. That is, a composite sheet having strength in a plurality of directions can be formed, and the shape of the corrugation can be changed by the rocking device, so that a composite sheet having strength according to the application can be formed.

According to the structure of the second composite sheet forming die apparatus of the present invention, the upper and lower slidable upper and lower sides are supported rotatably and swingably inside the sheet forming die.
Since the reinforcing fiber part forming die including the step blocks is provided, the vertical position of the linear part discharge hole can be adjusted by rotating the support shaft part without replacing the die.

Further, since the two blocks can swing independently and alternately, for example, a mesh-like reinforcing fiber portion can be formed in a composite sheet.
Therefore, a composite sheet having strength in a plurality of directions can be formed.
