Description

【発明の詳細な説明】 本発明は、農業用光反射シート、特に果樹周辺の地面に
敷いて使用する光反射シートの製造方法に関する。
リンゴ・桃等の果実は、適度の太陽光線を浴びることに
より、糖度と色合の優れた良好な品質に成育することが
知られている。
ところが、果樹に付着した成育途中の果実の底部や葉陰
になる部分は、太陽光線があたらないため、糖度と色合
が劣り品質にむらが生じる。
このため、果樹周辺の地面に、太陽光線の反射シートを
敷く方法が採られている。
このようなシートに関し、すでに多くの考案力なされて
いる。
その一つに、シートを貫通する小孔を設け、これにより
雨水等の排出をはかるものである。
しかるに、一般の反射シートは、金属薄膜を３むため、
前記小孔の切断面に金属薄膜が露出し、そこから腐食が
進行する欠点がある。
このような欠点を解消するため、何らかの方法で、小孔
の切断面を樹脂等で被覆する必要が生じる。
しかしながら、例えばシートに小孔を設けた後、これに
溶融した樹脂をコーティングし、さらに反対側から吸引
処理することによって、樹脂を、Ｊ４Ｌ内に引き込む方
法もあるが製造工程が多く、コストが高くつく。
そこでこの発明の目的は、極めて簡単な方法で上記のよ
うな必要性を満足できるようにした農業用光反射シート
の製造方法を提供するにある。
以下、本発明を添付図面にもとづいて説明する。
第１図及び第２図は、本発明の方法により製造された光
反射シートを示す。
図示のように、光反射シート１は、ポリエステル等の熱
可塑性合成樹脂フィルム２に、アルミニウム等の金ｘ蒸
着或は金属箔の貼り合せなどの方法で金属薄膜層３を形
成し、これを熱可塑性合成樹脂例えばポリエチレンより
成る接着剤４を介して、同じく熱可塑性合成樹脂より成
る基材５に積層し、適宜間隔の貫通小孔６を設けたもの
である。
前記基材５は、細帯状もしくはテープ状の合成樹脂例え
ばポリエチレンを編成したいわゆるクロスが好ましい。
しかしその他の耐水性、耐候性の良好な織布、或はシー
トであってもよい。
また、これに着色しておくこともできる。
前記フィルム２は、耐光・耐候・耐水性の良好な合成樹
脂を用いるのが好ましく、着色或は印刷を施しておくこ
とができる。
前記金属薄膜層３は、必ずしもシート１の全面にわたっ
て設けなくてもよく、例えばエッチングにより適当な間
欠部を形成しておくことができる。
前記小孔６の形状は任意である。
ただし、第１図に示すように、シート１の側縁部により
多くの小孔６を設けておくと、排水効果が良くなる。
この小孔６の内周に現れる金属薄膜層３の切断面は、第
２図に示すように、基材５及び（もしくは）接着剤４が
溶融した合成樹脂７により被覆されている。
即ち、小孔６を形成する際、パンチ又はピン８（第５図
乃至第８図）を接着剤４及び基材５の溶融点以上に加熱
しておき、シート１に突き刺すと。
熱溶融により容易に穿孔され小孔６を設けることができ
ると共に、溶融した合成樹脂がピン８に付着し、このピ
ン８を引き抜くとき、金属薄膜層３の切断面を被覆する
のである。
なお、ピン８を基材５の表面から突き刺しても、ピン８
に付着した溶融合成樹脂或は流下した溶融合成樹脂で金
属薄膜層３の切断面を被覆することができる。
具体的には、第３図に示すように、上板９に多数のピン
８を固定し、各ピン８に対向する凹所１０を設けた下板
１１の上面を、シート１が間欠的に通過するようにして
おぎ、シート１の停止時に上板９を降下させる。
或は、第４図に示すように、ピン８を固定したドラム１
２と、凹所１０を設けたドラム１３との間を、シート１
が通過するようにしてもよい。
前記ピン８の形状は、必要に応じて選択することができ
るが、例えば第５図に示すように、その外周にローレッ
トのような切り込み１４を設けておくと、溶融した合成
樹脂の保持性がよくなり、溶融した合成樹脂で、確実に
金属薄膜層３の切断面を被覆することができる。
第６図及び第７図に示すように、ピン８０周方向に１以
上の溝１５を設けても同様の効果がある。
また第８図に示すように、ピン８の外周に膨出部１６を
設けてもよい。
本発明によれば、以上の様に、加熱したピンで孔をあげ
るだけで、貫通小孔の切断面を合成樹脂で被覆できるの
で、優れた品質のシートを安価に提供することができる
等の利点がある。
