Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a sheet material used for construction and the like, and in particular, a metal vapor deposition layer is formed on the surface of the sheet for the purpose of shielding infrared rays, that is, for providing a heat insulating effect. Sheet material manufacturing method. More specifically, the present invention relates to a method for manufacturing a sheet material in which a metal vapor deposition layer is formed in a stripe shape in the longitudinal direction.

2. Description of the Related Art Conventionally, among building sheet materials, a sheet material is known as a heat insulating sheet material that has a metal such as aluminum vapor-deposited over its entire surface to block infrared rays and to provide a heat insulating effect. , A sheet material having a transparent portion without a metal vapor deposition layer in a stripe shape is also known so that it can be easily fixed with a fastener such as a nail when this sheet material is applied to a building pillar or the like. .

Conventionally, as a method of forming a metal vapor deposition layer in the longitudinal direction in a stripe shape on the surface of a sheet material, a so-called baffle plate having a plurality of longitudinal gaps formed on the surface of the sheet material is used. There has been a method of depositing a metal on the surface of a sheet material.

As another method, as shown in FIG. 4, metal is vapor-deposited on the entire film to form a metal vapor-deposited layer, the surface of the metal vapor-deposited layer is printed in stripes, and then an etching treatment is performed. There is also a method (so-called “etching method”) in which the metal vapor-deposited layer on the non-printed portion is removed by performing the above process.

As yet another method, as shown in FIG. 5, a water-soluble celite primer is applied to the upper surface of the vapor deposition anchor material at a portion corresponding to the non-evaporated portion, and metal vapor deposition is performed on the entire surface. A method of removing the metal vapor deposition corresponding to the portion of the celite primer by washing with water after applying (so-called "water washing method") has also been performed.

[0006]

Among the above-mentioned methods, in the method of depositing metal on the sheet surface through the baffle plate, the gap is usually only 15 mm or more, and the gap distance of the baffle plate is small. If it is about 1 to 5 mm, the vaporized metal particles will penetrate into the portion where the metal should not be vapor-deposited due to the baffle, the boundary portion will not exist, and the portion where the metal will not be actually vaporized will not exist. There was a risk that it would be in a state. Further, the striped vapor deposition product obtained by this manufacturing method has an economic problem such that the cost is considerably higher than that of the entire surface vapor deposition product.

Further, according to the etching method and the water washing method shown in FIGS. 4 and 5, not only is the process complicated, it is not suitable for continuous operation, but also the cost is high. When used, the printed part was unnecessary.

[0008]

The reinforcing material sheet is attached to the metal vapor deposition layer side of the sheet material via the molten resin, and the striped metal vapor deposition laminated sheet material is manufactured.

[0009]

In the figure, the delivery roll in which the sheet 11 having the metal vapor deposition layer 3 formed on the entire upper surface of the resin sheet 2 is wound up. The sheet 11 delivered from 10 is subsequently delivered to the cutting process. In this cutting process, the sheet 11 is
As shown in FIG. 5, the sheet is cut in the longitudinal direction by the plurality of cutting blades 12 and 12 which are arranged in the lateral direction (the direction perpendicular to the feeding direction of the sheet 11) at regular intervals. This cutting blade
Reference numerals 12 and 12 are arranged between a guide roll 14 and an expander roll 16 to be described later, and are rotatably mounted at regular intervals in the axial direction of the guide rod 18.

The cut sheet 11 subsequently passes through the expander roll 16, and at this time, the gaps 11a, 11a between the cut sheets are increased (divided). Specifically, this expander roll 16 has a shaft
