Description
【０００１】[0001]
本考案は、合成樹脂製フィルム、合成樹脂製シート、織物、紙等の薄箔状物を 巻き取るための薄箔状物用巻芯に関する。 The present invention relates to a thin foil core for winding a thin foil such as a synthetic resin film, a synthetic resin sheet, a woven fabric, and paper.
【０００２】[0002]
合成樹脂製フィルム、合成樹脂製シート、織物、紙等の薄箔状物を巻芯上に損 傷することなく、確実に巻き上げるには、薄箔状物の末端部を巻芯の軸芯に一致 させて固定する必要がある。 薄箔状物（以下、フィルムと称する）の末端部を巻芯上に固定させる方法とし ては、一般に、フィルムの末端部をガムテープや粘着テープによって固定する方 法があるが、ガムテープによる貼り付け方が不完全であったり、フィルムの末端 部が曲がったまま固定した場合には、フィルム巻取り中に、巻取り張力が左右不 均一になる。その結果、蛇行が起因し、巻装端面がタケノコ状になり、場合によ っては、部分的な「伸び」や「たるみ」のため、シワや折り重なりが発生する。 To reliably wind a thin foil-like material such as synthetic resin film, synthetic resin sheet, woven fabric, and paper onto the core without damaging it, use the end of the thin foil as the core of the core. It is necessary to match and fix. As a method of fixing the end of a thin foil (hereinafter referred to as a film) on the core, there is generally a method of fixing the end of the film with gum tape or adhesive tape. If the film is imperfect, or if the end of the film is bent and fixed, the winding tension becomes uneven during winding. As a result, the winding end surface becomes bamboo shoot-shaped due to the meandering, and in some cases, wrinkles and folding overlaps due to partial "stretching" and "slack".
【０００３】 一般に、フィルムは、加工や印刷の都度、巻き返しを行うことが多いが、その 際に、フィルム末端部の固定状態が大きく影響してフィルム表面の平滑さが失わ れ、繊細な印刷やコーティング処理を行う際には、巻装下層部分に不良品が発生 することになる。 さらに、図４に示すように、巻芯本体Ｂの軸線方向に感圧接着剤層Ａを直線状 に配し、この感圧接着剤層Ａ上にフィルムＦの末端部ｆを接着固定することが行 われている。In general, the film is often rewound each time it is processed or printed, but at that time, the fixing state of the film end portion largely affects the smoothness of the film surface, resulting in delicate printing or When performing the coating process, defective products will be generated in the lower layer of the winding layer. Further, as shown in FIG. 4, the pressure-sensitive adhesive layer A is arranged linearly in the axial direction of the core body B, and the end portion f of the film F is adhesively fixed onto the pressure-sensitive adhesive layer A. Is being carried out.
【０００４】 しかし、この場合は、巻芯本体Ｂ上に固着させたフィルムＦ（フィルム幅Ｌ） の両側に感圧接着剤層Ａの露出部ａが存在するから、巻芯本体Ｂ上にフィルムＦ を巻き始めると、フィルムＦの巻装力によって図５に示すように、感圧接着剤層 Ａの一部がはみ出し、さらに、図６に示すように、フィルムＦの巻装周圧力によ って縁部に感圧接着剤層Ａの盛上がり部ａ′が乗り上げることになる。そして、 図７に示すように、巻芯本体Ｂ上に巻装されたフィルムＦと次の層を成すフィル ムＦとの間に巻き込まれるという不具合が生ずることになる。However, in this case, since the exposed portions a of the pressure-sensitive adhesive layer A are present on both sides of the film F (film width L) fixed on the core body B, the film is formed on the core body B. When F 1 is started to be wound, the winding force of the film F causes a part of the pressure-sensitive adhesive layer A to protrude, and further, as shown in FIG. Therefore, the raised portion a ′ of the pressure-sensitive adhesive layer A rides on the edge portion. Then, as shown in FIG. 7, there is a problem that the film F wound on the core body B and the film F forming the next layer are caught.
【０００５】 一方、フィルム満巻後の取扱い中や輸送中に巻装物に衝撃や振動が作用すると 、図８のように、フィルムＦにタケノコ状の巻き崩れが発生することがあるが、 このような場合には、感圧接着剤層Ａの露出部ａにフィルムＦの側端部が接触し て感圧接着剤がフィルムＦ側に転移し、それに伴ってフィルムＦに異物が付着す ることがある。On the other hand, if shock or vibration is applied to the wound material during handling or transportation after the film is fully wound, a bamboo shoot-like collapse may occur in the film F as shown in FIG. In such a case, the side end of the film F comes into contact with the exposed portion a of the pressure-sensitive adhesive layer A, the pressure-sensitive adhesive is transferred to the film F side, and accordingly foreign matter is attached to the film F. Sometimes.
【０００６】 このようになったフィルムＦは、スリッターで細幅に切断したり、印刷加工し たり、表面コート処理を行う等の二次加工工程において異物が付着した部分が必 要ロスになる。 また、二次加工に伴う巻き替えの際、フィルムＦの側部に感圧接着剤が付着し ていると、遠心力や風圧によって感圧接着剤や感圧接着剤に付着した異物が飛散 したり、装置のロール等に転移し、これが再びフィルムＦに付着して巻き込まれ ることがある。このため、フィルムＦの側端部は、必要ロスとして破棄されるこ とになる。In the film F thus formed, a portion to which a foreign substance adheres becomes a necessary loss in a secondary processing step such as cutting with a slitter into a narrow width, printing processing, and surface coating processing. Also, if pressure-sensitive adhesive adheres to the side of film F during rewinding due to secondary processing, the pressure-sensitive adhesive and foreign substances adhered to the pressure-sensitive adhesive will be scattered by centrifugal force and wind pressure. Or, it may be transferred to a roll or the like of the apparatus, and this may adhere again to the film F and be caught. Therefore, the side edge of the film F is discarded as a necessary loss.
【０００７】[0007]
従って、薄箔状物用巻芯は、この巻芯上に巻装された薄箔状物の両端部を越え て感圧接着剤層が露出しないことが重要であり、そのためには、感圧接着剤層を 薄箔状物の幅内に確実に収めることが必要である。 本考案は、かかる知見に基づいてなされたものであり、その目的は、巻芯本体 上にフィルム等の薄箔状物を巻装する際に、フィルム両側部から感圧接着剤がは み出さないようにした箔状物用巻芯を提供することにある。 Therefore, it is important that the pressure-sensitive adhesive layer of the thin foil core is not exposed beyond both ends of the thin foil wound on the core. It is necessary to ensure that the adhesive layer fits within the width of the thin foil. The present invention has been made based on such knowledge, and its purpose is to prevent the pressure-sensitive adhesive from squeezing out from both sides of the film when winding a thin foil-like material such as a film on the core body. It is to provide a winding core for a foil-shaped material which is prevented.
【０００８】[0008]
上記の目的を達成し得る本考案の薄箔状物用巻芯は、巻芯本体の両端部に所定 の間隔を保持して付着阻止部を設けると共に、両付着阻止部間に巻芯本体の軸線 に平行な感圧接着剤層を配し、さらに、感圧接着剤層上に感圧接着剤層より一回 り大きな剥離シートを付着させたことを特徴とするものである。 A core for a thin foil-like object of the present invention that can achieve the above-mentioned object is provided with an adhesion preventing part at both ends of the core main body with a predetermined interval, and the core of the core main body is provided between both adhesion preventing parts. It is characterized in that a pressure-sensitive adhesive layer is arranged parallel to the axis and a release sheet larger than the pressure-sensitive adhesive layer is attached onto the pressure-sensitive adhesive layer.
【０００９】 このように、巻芯本体の両端部に所定の間隔を保持して付着阻止部を設けると 共に、両付着阻止部間に巻芯本体の軸線に平行な感圧接着剤層を配し、さらに、 感圧接着剤層上に感圧接着剤層より一回り大きな剥離シートを付着させたことに より、巻芯本体上にフィルム等の薄箔状物を巻装する際に、フィルム両側部分か ら感圧接着剤がはみ出さないようになる。As described above, the sticking preventing portions are provided at both ends of the winding core body with a predetermined space therebetween, and the pressure-sensitive adhesive layer parallel to the axis of the winding body is arranged between the sticking preventing portions. In addition, by attaching a release sheet that is slightly larger than the pressure-sensitive adhesive layer on the pressure-sensitive adhesive layer, it is possible to use a film when winding a thin foil-like material such as a film on the core body. The pressure sensitive adhesive will not stick out from both sides.
【００１０】 ここで、巻芯本体としては、紙、合成樹脂、金属製の管、或いはこれらを複合 化した管が好適である。 さらに、付着阻止部は、パラフィンやシリコン樹脂等の滑性や剥離性に富んだ 材料を巻芯本体の両端部に塗布することにより形成できるが、タックシール（付 着防止性の貼着シート）を張りつけることにより形成することもできる。この付 着防止部は、巻芯本体の両端部に局部的に設けてもよいが、全周に配してもよい 。Here, as the core body, a pipe made of paper, a synthetic resin, a metal, or a composite thereof is preferable. Furthermore, the adhesion-preventing portion can be formed by applying a material having a high slipperiness and peelability, such as paraffin or silicone resin, to both ends of the core body, but a tack seal (sticking sheet for preventing sticking) It can also be formed by sticking. The attachment preventing portion may be locally provided at both ends of the core body, or may be provided all around.
【００１１】 感圧接着剤としては、アクリル系の接着剤が好適である。 さらに、剥離シートとしては、基材となる帯状紙の片面にパラフィン、オレフ ィン系やシリコン系のワックスタイプの薄膜を積層したシート、或いはポリエチ レンフィルムやポリプロピレンフィルム等の感圧接着剤と円滑に剥離する合成樹 脂フィルムなどが好適である。An acrylic adhesive is suitable as the pressure-sensitive adhesive. Further, as a release sheet, a sheet in which a wax-type thin film of paraffin, olefin-based or silicon-based is laminated on one surface of a strip-shaped paper as a base material, or a pressure-sensitive adhesive such as polyethylene film or polypropylene film, and smooth A synthetic resin film that peels off is suitable.

以下、図面により本考案の実施例を説明する。 図１において、１は紙製の巻芯本体であり、巻芯は、巻芯本体１の両端周縁部 全周にパラフィンを塗布して付着防止部２ｇ，２ｈを形成した後、これら両付着 防止部２ｇ，２ｈ間に巻芯本体１の軸芯と平行に帯又はリボン状に感圧接着剤層 ２を配し、その上に、感圧接着剤層２をカバーするように帯又はリボン状の剥離 シート３を付着することにより形成されている。 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a paper core body. The core is formed by applying paraffin to the entire periphery of both ends of the core body 1 to form adhesion preventing portions 2g and 2h. A pressure-sensitive adhesive layer 2 is arranged between the portions 2g and 2h in a band or ribbon shape in parallel with the axis of the winding core body 1, and a band or ribbon shape is provided thereon so as to cover the pressure-sensitive adhesive layer 2. The release sheet 3 is formed by adhering.
【００１３】 ここで、感圧接着剤層２の塗布幅、換言すれば、付着防止部２ｇ，２ｈの最内 端部間の間隔は、巻芯本体１上に巻き取るフィルムＦの両側部からはみ出さない 幅（片側１０mm以内２mm以上）に規制することが必要である。 上記の巻芯本体１にフィルムＦを巻装すると、図２に示すように、フィルムＦ の両端部ｆ1 ，ｆ2 が付着防止部２ｇ，２ｈ上に位置することになり、フィルム Ｆの両端部ｆ1 ，ｆ2 に感圧接着剤が付着しないようになる。Here, the coating width of the pressure-sensitive adhesive layer 2, in other words, the distance between the innermost ends of the adhesion preventing portions 2g and 2h is determined from both sides of the film F wound on the core body 1. It is necessary to control the width so that it does not protrude (one side is within 10 mm and 2 mm or more). When the film F is wound around the core body 1 described above, as shown in FIG. 2, both ends f 1 and f 2 of the film F are located on the adhesion preventing portions 2g and 2h, and both ends of the film F are The pressure-sensitive adhesive does not adhere to the parts f 1 and f 2 .
