【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、人から発生する唾液が飛散することを防止す
るのに用いるマスクの製造方法に関するものである。TECHNICAL FIELD The present invention relates to a method for manufacturing a mask used to prevent the scattering of saliva generated by a person.
この種のマスクは、２枚重ねのナイロン製布地を素材と
して製造されている。従来のマスク製造方法では、棒状
の金属を電気的に加熱できるコテ（以降電気ゴテと称
す）を用い、この電気ゴテをナイロンの溶融温度まで加
熱し、電気ゴテの先端を２枚重ねしたナイロン製布地に
当て２枚の布地を熱溶着させ、しかる後に熱溶着部位の
一部を裁断し、外周縁が熱溶着されたマスクを製造して
いた。This type of mask is made of two layers of nylon fabric. In the conventional mask manufacturing method, a trowel (hereinafter referred to as an electric iron) that can electrically heat a rod-shaped metal is used, and this electric iron is heated to the melting temperature of nylon, and the tip of the electric iron is made of nylon. Two masks were applied to a cloth to be heat-welded, and then a part of the heat-welded portion was cut to manufacture a mask having an outer peripheral edge heat-welded.
上述した従来の電気ゴテによるマスクの製造方法は、２
枚重ねしたナイロン布地の溶着する部分を電気ゴテでな
ぞり、熱溶着させるため、電気ゴテによる布地のなぞり
速度を一定にする必要がある。The mask manufacturing method using the conventional electric iron described above is
In order to trace the heat-welded portion of the laminated nylon fabrics with an electric iron, it is necessary to make the trace speed of the fabric with the electric iron constant.
しかしながら、電気ゴテによる布地のなぞり作業は、手
作業で行われるため、なぞり速度を一定にすることが困
難であり、なぞり速度が遅い場合には、ナイロンが溶け
過ぎて固形物の状態でマスクの縁に融着し、逆なぞり速
度が速い場合には、溶着部分が不完全になり、裁断時に
剥がれが生じてしまうという欠点があった。However, it is difficult to keep the tracing speed constant because the tracing operation of the cloth with the electric iron is performed manually.When the tracing speed is slow, the nylon melts too much and the mask of the mask is in a solid state. In the case where the edges are fused and the reverse tracing speed is high, there is a drawback that the welded portion becomes incomplete and peeling occurs during cutting.
また、手作業であるため、多量にマスクを得るのが困難
であるという欠点があった。Further, there is a drawback that it is difficult to obtain a large amount of masks because it is a manual work.
