    摘要: 【課題】紙の表面に接着層を形成する等の特別な工程を必要とせずに、紙同士を接着することができ、剥離することも可能な接着紙及び接着紙の製造方法を提供すること。 【解決手段】接着紙PPは、複数の繊維を樹脂を介して結着して成形した紙P同士を加熱して接着され、剥離可能である。接着紙PPは、紙Pの厚み方向に樹脂が分散し、紙Pの表面に接着層を有さず、樹脂の一部を用いて接着される。接着紙PPにおいて、繊維に対する樹脂の量は8〜40%である。 【選択図】図2

    摘要: The adhesive tape comprises left and right boundary edges (l k, r k), a main carrier, and a first layer of self-adhesive on an obverse of the main carrier. The reverse of the main carrier bears parting systems (TS), which are suitable for causing an adhesive bond to a substrate that is parted again in such a way that sticky residues are left on the reverse of the main carrier or on the substrate in the region of the parted bond. The parting system is constructed in the form of a multiply interrupted stripe comprising segments that extend in the longitudinal direction of the adhesive tape. The adhesive tape comprises left and right boundary edges (l k, r k), a main carrier, and a first layer of self-adhesive on an obverse of the main carrier. The reverse of the main carrier bears parting systems (TS), which are suitable for causing an adhesive bond to a substrate that is parted again in such a way that sticky residues are left on the reverse of the main carrier or on the substrate in the region of the parted bond. The parting system is constructed in the form of a multiply interrupted stripe comprising segments that extend in the longitudinal direction of the adhesive tape (x direction). The boundary edge of each segment is represented by a line that, in relation to a right-handed Cartesian (orthogonal) coordinate system with an x-axis lying in the longitudinal direction of the adhesive tape and a y-axis standing perpendicular to the x-axis and pointing from left to right, meets the following conditions: a point lying furthest right E 1(x 1/Y m a x) (extreme) or a region B 1(extreme region), which encompasses points lying furthest right and bounded by the points E 1 a(x 1 a/Y m a x) and E 1 b(x 1 b/Y m a x), where X 1 aless than X 1 b; a point E 2(x m i n/Y 2) lying least far in the x direction or a region B 2, which encompasses points lying least far in the x direction and bounded by the points E 2 a(X m i n/Y 2 a) and E 2 b(X m i n/Y 2 b), where Y 2 aless than Y 2 b; a point E 3(X m a x/Y 3) lying furthest in the x direction or a region B 3, which encompasses points lying furthest in the x direction and bounded by the points E 3 a(X m a x/Y 3 a) and E 3 b(X m a x/Y 3 b), where Y 3 aless than Y 3 b; a rising line section (F s), which is bounded by the points E 2or E 2 band E 1or E 1 a; and a falling line section (F f), which is bounded by the points E 1or E 1 band E 3or E 3 b. The steepness in the rising line section is lower than the steepness in the falling line section. The extent of the individual segments in the x direction is lower by a multiple than the extent of the adhesive tape in the x direction. The extent of the stripe formed by the segments in the transverse direction of the adhesive tape (y direction) is lower than the extent of the adhesive tape in that direction or is lower than the width of the adhesive tape. The stripe constitutes a sequence of identical segments and identical distances between the segments. The segments are arranged one after another in the x direction. The segments comprise a further carrier (two-dimensionally splittable or delaminable segment carrier), which is provided on each of its obverse and its reverse with a layer of adhesive. The segment carrier is a single-ply paper, an assembly of layers, an assembly of two film layers, or an assembly of a paper layer or a film layer. The segments comprise a polymer compound, which effects the adhesive bond. The polymer is applied to the reverse of the adhesive tape by printing or gravure printing. The segment boundary line in the course of the vertex lying least far in the x direction and/or in the course of the vertex lying furthest in the x direction is differentiated mathematically. The parting systems on the adhesive tape reverse have different geometries. An independent claim is included for a method of joining two flat webs during the flying splice of flat-web material wound up to form rolls.

    摘要: 本発明は、合成繊維を使用しなくても、マスキングテープを伸び易くして追従性を改善し、かつ十分な引き裂き強度によってテープ切れを防止できる含浸塗工タイプ和紙マスキングテープ基材を提供することを課題とする。鋭意研究の結果、10〜70重量%のマーセル化針葉樹パルプにクラフトパルプを配合した機械抄き和紙を用いることで、課題を解決したテープ基材を得ることができ、本発明を完成するに至った。従来のように伸び易いが結束を発生し易い合成繊維を用いなくても、基材の追従性を向上でき、さらに、十分なマスキングテープの引き裂き強度を得ることができる。合成繊維を使用しなければ合成繊維による結束を回避でき均質な和紙を得ることができる。和紙には合成繊維を配合しないことが望ましいが、より高い引き裂き強度を得るために少量であれば合成繊維を配合しても良い。
