いられている。Tanks, etc. that generally require heat retention or welfare insulation IIc
A plate-shaped heat insulating band is wrapped around the outer circumferential surface of the heat insulating band, but many companies use a fibrous layered material formed by stacking inorganic fibers such as rock wool or glass wool in layers as this insulating band. .

る。When using this fiber layered material as a heat insulation zone, by arranging the heat insulation zone formed so that the fiber direction is perpendicular to the outer surface of the tank, the distortion due to compressive force from the outside of the tank can be reduced. In addition, it prevents the fibers from peeling off and allows it to fully perform its function as a heat insulator.

な繊維層状体を保温帯として使用する場合には、繊維方
向を保温帯の板厚方向に変更する工程が必要をなる。However, in the production of fibrous layered bodies, generally, inorganic short fibers are spread in layers on a net conveyor, and a thermosetting resin adhesive is sprayed simultaneously with the scattering of the short fibers or after the scattering. Since the fibrous layered body is formed by adhesion and curing to a certain thickness, the fiber direction is formed along the longitudinal horizontal direction of the fibrous layered body. Therefore, when such a fibrous layered body is used as a heat-insulating band, a step of changing the fiber direction to the thickness direction of the heat-insulating band is required.

They are accumulated in a layered manner and are bonded in an entangled state with each other using a liquid adhesive, for example, a thermosetting resin such as a phenolic resin, which is also sprayed by the nozzle 4.
Continuously formed into a fiber layered body 7, and this fiber layered body γ is placed on the net conveyor 3? ffless compression roller 5,
5' and 6. v and Kl! It is compression molded to a predetermined thickness by passing through a heating chamber (not shown). Note that the fiber direction of each of the fiber layered bodies 7 is arranged in a pattern IlK mainly along the longitudinal horizontal direction of the fiber layered body 7.

る。The fiber layered material 7 that has been processed in this way advances on a transfer conveyor 8, which is a first conveyance means, and passes below a cutting device 9, where it is cut by a cutting device 9 whose blade descends at regular intervals. The IIaIjA layered body 7 is cut one unit at a time in a rectangular direction perpendicular to the direction of travel, and is continuously formed as cut pieces 10 in the same direction. Note that the speed of the transfer conveyor 8 and the descending time interval of the blade of the cutting device S are strictly controlled, so that the width of each cut piece 100 is kept constant.

志を水平方向において圧接集積することができる。The cut pieces 10 thus formed further advance on the transfer conveyor 8 and pass through the stepped portion 1 between the transfer conveyor 8 and the cut pieces 10.
1 is formed on the transfer conveyor 12, which is the second conveyance means, the fiber direction is changed from the previous horizontal direction to the vertical direction. will be changed to The speed of this transfer comparer 120 is adjusted to be slightly faster than that of the transfer conveyor 8. For example, in FIG. When moving,
Care is taken not to contact the cut piece 101 in the front. Further, the step portion 11 is set in response to changes in the shape of the cut piece 10, etc. For example, if the step is too large and the cut piece 10 is rotated by 180 degrees, or if the step is too small and the cut piece 10 is rotated 180 degrees, Care is taken to prevent the piece 10 from sliding onto the transfer conveyor 12 without rotating. In general, the step width is set around approximately A of the height H of the cut piece 10 transferred onto the transfer conveyor 12, and is determined based on various conditions, such as the relationship with the width W of the cut piece 10, and the width of the cut piece 10. Considering the position of the center of gravity, the raw material of the fiber layered material, the speed of each transfer conveyor 8, 120, etc., the transfer conveyor 12 is not limited to the setting table, and even if the transfer conveyor 12 is placed at a higher position. Bread conveyor 1, which is a conveying means, is connected at approximately the same height as the bread conveyor 1.
Move to the top of 3. The speed of this bread conveyor 13 is
to the same extent as transfer conveyor 8, i.e. transfer conveyor 1
By adjusting the speed slightly slower than the speed of 2, the cut pieces 10 moving one after the other on the pan conveyor 13 can be piled up in pressure contact with each other in the horizontal direction.

プレーに代わってロールコータ方式を採用してもよい。The collection of cut pieces 14 that are pressed against each other in the horizontal direction is transported with the top surfaces held at approximately the same height by the horizontal bottom surface of the pan conveyor 13, and passes below the adhesive application device 15. At this time, the hot melt adhesive, which has been heated and melted to a predetermined temperature in advance in the device 15, is also sprayed by the spray gun 16 to form a hot melt coating layer on the upper surface of the assembly 14. Following this adhesive application step, the protective sheet 18 supplied from the sealer 17 is adhered at the pressure roller 1!1 while covering the upper surface of the stack 14 through the adhesive coating layer. , it is possible to obtain a heat-retaining material in which a predetermined surface coating layer is continuously formed. In addition, although the method of spraying hot melt adhesive was explained in the above example, other polymer adhesives or inorganic adhesives may be used, and a roll coater method may be used instead of spraying. May be adopted.

れるようにしたものである。2 to 5 show various embodiments in which the fiber direction of the cut piece 10 is changed at the stepped portion 11. 2nd v: J#i shows an example in which the cut pieces 10 transferred from the transfer conveyor 8 onto the transfer conveyor 12 have a vertically elongated shape. When the lower ends of the pieces 100 come into contact, the transfer conveyor 8 is busy supporting the surface of the cut pieces 100, so that the cut pieces 10 can stand on their own on the transfer conveyor 12. 3rd WJ and 4th figure welfare transfer conveyor 8
This shows an embodiment in which the cut pieces 10 transferred onto the transfer conveyor 12 are shaped horizontally; however, in the former case, the top surface of the transfer conveyor 120 is slightly lower than the top surface of the transfer conveyor 8. A stepped portion 11 is provided at the top of the transfer conveyor 1, and the cut pieces 10 sent from the transfer conveyor 8 are transferred to the transfer conveyor 1.
2, the fiber direction is changed.
The cut pieces 10 are transferred onto the transfer conveyor 12 by providing the stepped portion 11 at a higher position and forcing the cut pieces 10 onto the transfer conveyor 12. Moreover, FIG. 5 shows an embodiment in which the cut pieces 10 transferred onto the transfer conveyor 12 cannot stand on their own, and in this case, the speed of the transfer conveyor 12 is adjusted to be slow and the transfer is stopped. The cut piece that has just been removed leans on the cut piece that was transferred earlier for support, thereby maintaining its independence.
