本発明は、テニスコート等の運動施設或いは住宅のベラ

。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for manufacturing a water-permeable artificial lawn used for sports facilities such as tennis courts, or residential balconies.

という）があった。(Prior art) Conventionally, permeable artificial lawns are produced by planting synthetic resin grass leaves on a base fabric at arbitrary intervals to create an artificial lawn base material, and while conveying this base material with a belt conveyor etc. A thermoplastic resin such as rubber latex or low-density polyethylene is applied to the back side of the base fabric, and then passed through a drying chamber heated to around 100°C to form a backing layer. A manufacturing method (conventional example 1) by drilling small-diameter water permeable holes in the backing layer using
).

）もあった。There is also a manufacturing method (referred to as Conventional Example 2) in which a small diameter water permeable hole is made by piercing the backing layer with a rod to make the hole heated to about 300° C. or higher.
（発明が解決しようとする課題）

った。(Problem to be Solved by the Invention) However, in Conventional Example 1, since the rubber latex, low-density polyethylene, etc. forming the backing layer exhibits flexible and tough characteristics, a large piercing force is required to perform needle pricking. However, the pores are almost completely restored and it is not possible to form complete water permeable pores, making it difficult to exhibit sufficient water permeability. In particular, in the case of artificial turf containing sand, there is a problem in that the water permeability holes are almost restored and blocked by the load of the sand.
従来例２では、孔開は加工に要する力は小さくてもよい
が、基布が連続的に移動している為、透水孔が孔開は棒
の貫通時間に応じた長孔となり、必要以上に大きなもの
となってしまうという問題があった。In Conventional Example 2, the force required for drilling the hole may be small, but because the base fabric is continuously moving, the water permeable hole becomes a long hole corresponding to the penetration time of the rod, and the force required for processing is less than necessary. The problem was that it became a big problem.

である。(Means for Solving the Problems) The present invention involves intermittently moving a thermoplastic resin base fabric on which synthetic resin grass blades are planted and a backing layer formed on the back side, and when stopping, the backing layer and base fabric are moved. The above-mentioned problem is solved by heating the holes in the fabric and forming water-permeable holes using a rod.

であるので、好ましい。In the present invention, in order to intermittently move the thermoplastic resin base fabric that is continuously sent out from the heating drying process, it is recommended to use a dancer roll that moves up and down, which has a simple mechanism. Therefore, it is preferable.

The receiver is provided on opposite sides with the base fabric in between, and the receiver is reciprocated toward the plate by a cam.
This is preferable because it allows you to drill holes of the required size with a small amount of force.

If the diameter is smaller than 2M, the formed permeable holes are likely to become clogged (if the diameter is larger than 10mm, the holes will be visible from the surface, and in the case of artificial grass containing sand, the sand will easily flow out).

必要である。To heat the hole-opening rod, it is necessary to incorporate a heating element inside or attach a heating element to the outer surface of the base and heat it to 300°C or higher.
