Description

本明細書に引用される全ての特許、特許書類、及び刊行物の全ての開示内容が、参照により組み込まれる。上記の詳細な説明及び実施例は、理解しやすいように示したものにすぎない。したがってこれらによって不要な限定がなされることはないことは理解されたい。本発明は図示及び記載された細部そのものに限定されず、当業者に明白な変形形態は、特許請求の範囲によって定義される本発明の範囲内に含まれる。
例示的実施形態について以下に述べる。
［１］
フィルムの巻き取りコアであって、（ａ）外面及び長手方向軸を有する円筒管と、（ｂ）前記円筒管の前記外面に配設された、互いに反対側にある内側及び外側を有するポリマーネットを含むコアカバーと、を含み、前記ポリマーネットは、シート形態に配置された複数のポリマーリボン及び複数のポリマーストランドのアレイを含み、各ポリマーリボンが１つ又は２つの隣接するポリマーストランドに結合され、各ポリマーストランドが１つ又は２つの隣接するリボンに結合されており、
（１）各ポリマーリボンは、長さが幅及び高さよりも長くなるような、幅、高さ、及び長さを有し、長手方向軸を画定する細長い形状であり、
（２）各ポリマーストランドは、長さが幅及び高さよりも長くなるような、幅、高さ、及び長さを有し、１つ又は２つの隣接するポリマーリボンに断続的に複数回結合され、
（３）前記ポリマーネットの前記内側は、前記円筒管の前記外面に面している、
巻き取りコア。
［２］
前記ポリマーネットは、前記ポリマーリボンの前記長手方向軸が前記円筒管の前記長手方向軸に対して実質的に平行又は実質的に垂直となるように方向付けられている、［１］に記載の巻き取りコア。
［３］
前記ポリマーネットが、中間接着剤によって前記円筒管の前記外面に結合されている、［１］に記載の巻き取りコア。
［４］
（ａ）［１］に記載のフィルムの巻き取りコアと、（ｂ）前記フィルムの巻き取りコアの周りに巻かれたフィルムのウェブと、を含む、フィルムロール。 The entire disclosures of all patents, patent documents, and publications cited herein are incorporated by reference. The above detailed description and examples have been given for clarity only. Therefore, it should be understood that they do not impose unnecessary limitations. The invention is not limited to the exact details shown and described, and modifications obvious to those skilled in the art are included within the scope of the invention as defined by the appended claims.
Exemplary embodiments are described below.
[1]
A wound core of film, comprising: (a) a cylindrical tube having an outer surface and a longitudinal axis; and (b) a polymer net disposed on the outer surface of the cylindrical tube, having opposite inner and outer sides. A core cover comprising: a plurality of polymer ribbons and an array of polymer strands arranged in sheet form, wherein each polymer ribbon is bonded to one or two adjacent polymer strands. Wherein each polymer strand is bonded to one or two adjacent ribbons,
(1) each polymer ribbon has a width, height, and length such that the length is greater than the width and height, and is an elongated shape defining a longitudinal axis;
(2) each polymer strand has a width, height, and length such that the length is greater than the width and height and is intermittently bonded multiple times to one or two adjacent polymer ribbons; ,
(3) the inner side of the polymer net faces the outer surface of the cylindrical tube;
Rewind core.
[2]
The polymer net according to [1], wherein the polymer net is oriented such that the longitudinal axis of the polymer ribbon is substantially parallel or substantially perpendicular to the longitudinal axis of the cylindrical tube. Rewind core.
[3]
The winding core according to [1], wherein the polymer net is bonded to the outer surface of the cylindrical tube by an intermediate adhesive.
[4]
A film roll, comprising: (a) the film winding core according to [1]; and (b) a film web wound around the film winding core.
