【考案が解決しようとする課題】 前記特公昭４３−６１５７号公報の装置では、チューブ状フィルムの４面に放 電処理面を形成するとはいっても、面の全体が放電処理面になるのは第１フィル ム層の、放電電極と離れて対向した外面だけであって、第１フィルム層の内面、 及び第２フィルム層の外面と内面の３面はアースローラ電極の誘電体層の外周に 巻いたシートの織目や、網目に対応した部分的な点状に放電処理がなされるだけ で、４面の全体を放電処理面にすることはできない。又、上記シートの織目や、 網目には、チューブ状フィルムに付着したタルク、クレー等の滑剤が侵入して目 詰りが生じる。織目や網目が侵入物で完全に詰り、空間が無くなると、コロナ放 電は生じなくなるので、その際は運転を中止し、シートを新しいものと交換しな ければならず、手数がかゝる。又、特開平７−８８５７号公報の方法では第１フ ィルム層の内面と、第２フィルム層の内面の夫々全体を放電処理面にすることが できるので、肉類を内面に密着して包装する袋の製造には適するが、第１フィル ム層と第２フィルム層の外面は放電処理されないため、表面に印刷をしたり、文 字などを書くことはできない。そして、該公報に記載してあるように、放電処理 後にチューブ状フィルムを切開して拡げ、放電処理面に粘着テープの一部を貼着 しながら所定の方法で折り畳んでロール状に巻き、放電処理がされていない第１ フィルム層と第２フィルム層の外面で被塗装物の一部を覆い、第１フィルム層と 第２フィルム層の放電処理面に余分な塗料が付着するようなロール巻きのマスキ ングフィルムにする場合は、外折り式のロール巻きマスキングフィルムしか作る ことができない。即ち、ロール巻きマスキングフィルムには外折り式と、内折り 式の二種類があり、内折り式は第１フィルム層と第２フィルム層の外面が放電処 理面になっていないと作れないからで、それには特開昭５１−１８７７０号公報 に記載されているように第１フィルム層の外面と第２フィルム層の外面を別々に 放電処理しなければならない。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the device of Japanese Patent Publication No. 43-6157, although the discharge treated surfaces are formed on the four surfaces of the tubular film, the entire surface is the discharge treated surface. Only the outer surface of the first film layer facing away from the discharge electrode, the inner surface of the first film layer, and the outer surface and the inner surface of the second film layer are the outer surface of the dielectric layer of the earth roller electrode. Only the discharge treatment is performed on the texture of the rolled sheet or the partial dots corresponding to the mesh, and the entire four sides cannot be used as the discharge-treated surface. In addition, the weave or mesh of the sheet is clogged with lubricant such as talc and clay adhering to the tubular film. If the weave or mesh is completely clogged with intruding material and the space is exhausted, corona discharge will not occur, and in that case, the operation must be stopped and the seat must be replaced with a new one, which is troublesome. It Further, in the method disclosed in Japanese Patent Laid-Open No. 7-8857, the inner surface of the first film layer and the inner surface of the second film layer can be entirely treated as an electric discharge treated surface, so that meat can be closely attached to the inner surface for packaging. It is suitable for the production of bags, but since the outer surfaces of the first film layer and the second film layer are not subjected to electrical discharge treatment, it is not possible to print or write letters on the surfaces. Then, as described in the publication, after the electric discharge treatment, the tubular film is cut open and expanded, and a part of the adhesive tape is attached to the electric discharge treated surface while being folded in a predetermined method and wound into a roll, A roll winding in which a part of the object to be coated is covered with the outer surfaces of the untreated first film layer and second film layer, and excess paint adheres to the discharge-treated surfaces of the first film layer and the second film layer. When using a masking film, it is only possible to make an external folding roll-wound masking film. That is, there are two types of roll-wound masking film, an outer folding type and an inner folding type. The inner folding type cannot be produced unless the outer surfaces of the first film layer and the second film layer are the discharge treatment surface. Therefore, the outer surface of the first film layer and the outer surface of the second film layer must be separately subjected to electric discharge treatment as described in JP-A-51-18770.

A striped discharge treated surface is formed on the inner surface of the first film layer and the inner surface of the second film layer, and the striped discharge treated surfaces on the inner surfaces of both film layers are connected adjacent to each other. This made it possible to use the entire four surfaces of the tubular film as discharge-treated surfaces.

The first film layer is an upstream corona film. The second film layer is brought into contact with the outer circumference of the earth roller electrode of the discharge device, and the second film layer is brought into contact with the outer circumference of the earth roller electrode of the downstream corona discharge device, and the output of the high frequency power is output to the discharge electrode of each corona discharge device. Is applied to rotate the pinch roller and the ground roller electrode of each corona discharge device to drive the tubular film to move to the tubular film made of synthetic resin. In the Rona discharge treatment device, each film layer adheres to the inner surface on the outer circumference of the dielectric layer of the earth roller electrode of the upstream corona discharge device and the outer circumference of the dielectric layer of the earth roller electrode of the downstream corona discharge device. A groove that forms a striped discharge surface is formed by displacing the position between the upstream earth roller electrode and the downstream earth roller electrode, and the entire outer surface of the second film layer is formed by the upstream corona discharge device. As the discharge treatment surface, and a striped discharge treatment surface is formed on the inner surface of the layer and the inner surface of the first film layer, and the entire outer surface of the first film layer is changed to the discharge treatment surface by the downstream corona discharge device. In addition, a striped discharge-treated surface is formed between the inner surface of the layer and the inner surface of the second film layer between the stripes of the striped discharge-treated surface by the upstream corona discharge device.

【００１３】 各フィルム層が環状溝１５，２５の内部に押し込まれる程度は、各フィルム層 をアースローラ電極の外周に押付ける接圧によって制御することができる。この 接圧は、チューブ状フィルム内に封入する気体の量と、押圧板１６が第２フィル ム層を介して第１フィルム層をアースローラ電極の外周に平らに押付ける押圧力 や、押圧板２６が第１フィルム層を介して第２フィルム層をアースローラ電極の 外周に平らに押付ける押付力によって制御することができる。例えば、押圧板の 押圧力が一定である場合に、空気量を大にすると接圧は大になり、又、空気量が 一定である場合に押圧板の押圧力を大にすると接圧は大になる。勿論、空気量と 押圧板の押圧力の双方を調整し、接圧を制御してもよい。The degree to which each film layer is pressed into the inside of the annular grooves 15 and 25 can be controlled by the contact pressure that presses each film layer against the outer circumference of the earth roller electrode. This contact pressure is the amount of gas enclosed in the tubular film and the pressing force with which the pressing plate 16 presses the first film layer flatly on the outer circumference of the earth roller electrode via the second film layer. 26 can be controlled by the pressing force that presses the second film layer through the first film layer evenly on the outer circumference of the earth roller electrode. For example, when the pressing force of the pressing plate is constant, the contact pressure is large when the air amount is large, and when the pressing force of the pressing plate is large when the air amount is constant, the contact pressure is large. become. Of course, both the air amount and the pressing force of the pressing plate may be adjusted to control the contact pressure.
【００１４】 このようにして接圧を大にすると、図３に示すように、第１フィルム層が上流 のコロナ放電装置１０のアースローラ電極の外周に接触した際、第１フィルム層 の、誘電体層の環状溝１５に対応した部分は大きく伸び、環状溝１５の両側壁と 、底壁の内面に密着する。この状態でピンチローラ３，４及び、アースローラ電 極１３，２３を回転駆動してチューブ状フィルムＴを進行させながら、放電処理 を行うと、チューブ状フィルムの、放電電極のカバーの上端に摺接した第２フィ ルム層の外面全体に放電処理面が形成され、第２フィルム層の内面、及び第１フ ィルム層の内面には環状溝１５に対応した縦縞の放電処理面が形成される。When the contact pressure is increased in this way, as shown in FIG. 3, when the first film layer comes into contact with the outer periphery of the earth roller electrode of the upstream corona discharge device 10, the dielectric constant of the first film layer is increased. The portion of the body layer corresponding to the annular groove 15 extends greatly and adheres to both side walls of the annular groove 15 and the inner surface of the bottom wall. In this state, the pinch rollers 3 and 4 and the earth roller electrodes 13 and 23 are rotationally driven to advance the tubular film T, and when the discharge treatment is performed, the tubular film slides on the upper end of the discharge electrode cover. A discharge-treated surface is formed on the entire outer surface of the second film layer in contact with the inner surface of the second film layer and an inner surface of the first film layer with vertical stripes corresponding to the annular groove 15. .
【００１５】 つまり、放電電極１１の先端と第２フィルム層との間の放電により、第２フィ ルム層の外面全体が放電処理面になり、又、電極１１の先端と、アースローラ電 極間のエアギャップ内の放電により第２フィルム層の内面と、第１フィルム層の 内面には環状溝に対応した縦縞の放電処理面が形成されるのである。That is, due to the discharge between the tip of the discharge electrode 11 and the second film layer, the entire outer surface of the second film layer becomes a discharge treated surface, and the tip of the electrode 11 and the earth roller electrode are connected. By the electric discharge in the air gap, vertical discharge-treated surfaces corresponding to the annular grooves are formed on the inner surface of the second film layer and the inner surface of the first film layer.
【００１６】 チューブ状フィルムの第２フィルム層の外面が接触する下流のコロナ放電装置 ２０のアースローラ電極２３の誘電体層２４の外周には、前述したように上流の アースローラ電極１３の外周の誘電体層１４に設けた環状溝１５と正確に喰違わ せて環状溝２５が設けてある（図３参照）。As described above, the outer circumference of the dielectric layer 24 of the earth roller electrode 23 of the downstream corona discharge device 20 in contact with the outer surface of the second film layer of the tubular film is the outer circumference of the upstream earth roller electrode 13 as described above. An annular groove 25 is provided so as to exactly overlap with the annular groove 15 provided in the dielectric layer 14 (see FIG. 3).
【００１７】 従って、チューブ状フィルムが下流のコロナ放電装置２０の放電電極２１とア ースローラ電極２３の間を通過する際に、該アースローラ電極の外周に接触する 第２フィルム層の誘電体層２４に対する接圧を大にし、第２フィルム層を環状溝 ２５の部分で伸ばして溝の両側壁と底壁の内面に密着させて放電処理すると、上 流のコロナ放電装置が放電処理面を形成したのと同じ原理で、放電電極のカバー ２２の下端に摺接した第１フィルム層の外面全体に放電処理面が形成されると共 に、第１フィルム層の内面と、第２フィルム層の内面には、上流のコロナ放電装 置１０が第２フィルム層と、第１フィルム層の内面に形成した縦縞の放電処理面 の行間に縦縞の放電処理面が形成される。Therefore, when the tubular film passes between the discharge electrode 21 and the ground roller electrode 23 of the downstream corona discharge device 20, the dielectric layer 24 of the second film layer that contacts the outer circumference of the ground roller electrode. The discharge pressure was increased by increasing the contact pressure with respect to the second film layer at the portion of the annular groove 25 and closely contacting both side walls of the groove and the inner surface of the bottom wall, and the upper corona discharge device formed the discharge treated surface. According to the same principle as described above, the discharge treatment surface is formed on the entire outer surface of the first film layer which is in sliding contact with the lower end of the cover 22 of the discharge electrode, and the inner surface of the first film layer and the inner surface of the second film layer are formed. The vertical corona discharge device 10 has vertical stripe discharge-treated surfaces between the second film layer and the vertical stripe discharge-treated surfaces formed on the inner surface of the first film layer.
【００１８】 この場合、上流のコロナ放電装置１０が第１フィルム層と、第２フィルム層の 内面に形成した縦縞の放電処理面の行間の全域に、下流のコロナ放電装置２０が 縦縞の放電処理面を形成するようにすると、第１フィルム層の内面の全体と、第 ２フィルム層の内面の全体を放電処理面にすることができる。例えば、上流のコ ロナ放電装置１０で第２フィルム層と、第１フィルム層の両方の内面に幅３０ｍ ｍの縦縞放電処理面を３０ｍｍの行間で形成し、下流のコロナ放電装置２０が第 １フィルム層と、第２フィルム層の両方の内面に、上記縦縞放電処理面の行間に 、これと等しい３０ｍｍの幅の縦縞放電処理面を形成すれば、第１フィルム層の 内外両面の全体と、第２フィルム層の内外両面の全体が放電処理面になる。In this case, the upstream corona discharge device 10 has a vertical stripe discharge process on the first film layer and the vertical stripe discharge treatment surface formed on the inner surface of the second film layer with the vertical stripe discharge process on the entire area between the rows. When the surface is formed, the entire inner surface of the first film layer and the entire inner surface of the second film layer can be the discharge-treated surface. For example, in the upstream corona discharge device 10, vertical stripe discharge-treated surfaces having a width of 30 mm are formed on the inner surfaces of both the second film layer and the first film layer with a space of 30 mm, and the downstream corona discharge device 20 is used as the first discharge device. If a vertical stripe discharge treated surface having a width of 30 mm, which is equal to this, is formed on the inner surfaces of both the film layer and the second film layer between the rows of the vertical stripe treated discharge, the entire inner and outer surfaces of the first film layer, The entire inner and outer surfaces of the second film layer are the discharge-treated surface.
【００１９】 又、上流のコロナ放電装置１０が第２フィルム層の外面全体を放電処理面にし 、第２フィルム層の内面と、第１フィルム層の内面に夫々所定の行間の縦縞放電 処理面を形成し、下流のコロナ放電装置２０が第１フィルム層の外面全体を放電 処理面にし、第１フィルム層の内面と、第２フィルム層の内面に、上流のコロナ 放電装置が形成した縦縞放電処理面の行間に、この行間よりも幅が狭い縦縞放電 処理面を形成し、第１フィルム層の内面と、第２フィルム層の内面に行間を保っ た縦縞放電処理面を形成することもできる。例えば、上流のコロナ放電装置１０ で第２フィルム層と、第１フィルム層の両方の内面に幅５ｍｍの縦縞放電処理面 を１５ｍｍの行間で形成し、下流のコロナ放電装置２０が第１フィルム層と、第 ２フィルム層の両方の内面に、上記縦縞放電処理面の１５ｍｍの行間の中央に幅 ５ｍｍの縦縞放電処理面を形成すれば、これにより第１フィルム層と、第２フィ ルム層の両方の内面に５ｍｍの幅の縦縞放電処理面を５ｍｍの行間で形成し、縦 縞放電処理面の行間の５ｍｍがヒートシール可能になるのである。Further, the corona discharge device 10 on the upstream side makes the entire outer surface of the second film layer the discharge treated surface, and the inner surface of the second film layer and the inner surface of the first film layer respectively have vertical stripe discharge treated surfaces between predetermined rows. The corona discharge device 20 on the downstream side forms the entire outer surface of the first film layer as the discharge-treated surface, and the vertical stripe discharge process formed on the inner surface of the first film layer and the inner surface of the second film layer by the upstream corona discharge device. It is also possible to form a vertical stripe discharge treated surface having a width narrower than the space between the rows, and to form a vertical stripe discharge treated surface having a space between the inner surfaces of the first film layer and the second film layer. For example, in the upstream corona discharge device 10, vertical stripe discharge-treated surfaces having a width of 5 mm are formed on the inner surfaces of both the second film layer and the first film layer at intervals of 15 mm, and the downstream corona discharge device 20 uses the first film layer. By forming a vertical stripe discharge treated surface having a width of 5 mm at the center of the 15 mm line of the vertical stripe discharge treated surface on both inner surfaces of the second film layer, the first film layer and the second film layer are thereby formed. Vertical striped discharge-treated surfaces having a width of 5 mm are formed on both inner surfaces with 5 mm rows, and 5 mm between the vertically striped discharge-treated surfaces can be heat-sealed.
【００２０】 上流のコロナ放電装置１０のアースローラ電極の誘電体層１４の外周と、下流 のコロナ放電装置２０のアースローラ電極の誘電体層２４の外周に位置を喰違わ せて設ける縞状放電処理面を形成するための溝１５，２５は、図示の軸方向に間 隔を保った環状溝に限定されず一条又は複数条の螺旋状の溝にし、斜めの縞状放 電処理面を形成するようにしてもよいし、円周方向に間隔を保った一条又は複数 条の軸方向の溝にし、横縞状の放電処理面を形成するようにしてもよい。Striped discharges provided at different positions on the outer circumference of the dielectric layer 14 of the earth roller electrode of the upstream corona discharge device 10 and the outer circumference of the dielectric layer 24 of the earth roller electrode of the downstream corona discharge device 20. The grooves 15 and 25 for forming the processing surface are not limited to the annular grooves which are spaced from each other in the axial direction shown in the drawing, but may be one or a plurality of spiral grooves to form a diagonal striped discharge processing surface. Alternatively, one or more axial grooves may be formed at intervals in the circumferential direction to form a horizontal striped discharge-treated surface.
