題があった。A method for manufacturing a double conveyor, which is generally used as a method for manufacturing a soft slab, such as a continuous urethane soft block manufacturing line U manufactured by Maruka Kakoki Co., Ltd.
If the BT type is applied, the above problems such as jig foaming are solved, and it becomes possible to continuously produce large-sized foam blocks. However, the open-cell structure produced by the double conveyor is used. The rigid urethane foam has a desired movement since it moves in the traveling direction of the conveyor while rising, and is pressed by the upper conveyor, so that the orientation ratio of the cell becomes small and, as a result, the cell diameter in the heat insulating direction becomes large. There was a problem that the heat insulation performance could not be obtained.

While moving further, the front upper conveyor 19 of the upper conveyor 11 has a higher moving speed than the lower conveyor 12 and is provided with an inclination so that the height interval between the inlet portion 20 and the outlet portion 21 is narrowed. Therefore, the foam is on the front upper conveyor 19
While being pushed by and moving forward while receiving shearing force in the forward state. Next, it moves from the front upper conveyor 19 to the lower conveyor 12 and the rear upper conveyor 22 at a constant speed, and is sandwiched and moved to the double conveyor 13 until curing, taken out, and the molding is completed. The block 14 from which the skin layer has been removed from the obtained large block hard urethane foam 10 is cut in the conveyor flow direction to obtain the core material 8.

す。The cell orientation ratio of the core material 8 thus obtained,
The results of measuring the density and the thermal conductivity of the vacuum heat insulating material pack 7 which is covered with the core material 8 and hermetically sealed under reduced pressure are shown in (Table 1).

を示すことがわかる。As is clear from Table 1, when the moving speed of the front upper conveyor 19 is made higher than that of the lower conveyor 12 and the moving speeds of the upper and lower conveyors are made different from each other, the front upper conveyor 19 is inclined. It can be seen that there is less variation and more excellent heat insulation performance is exhibited.
