Abstract
(EN)
In order to provide a winding core for a film, capable of preventing winding displacement and a polyvinyl alcohol film roll using the winding core, provided is a winding core 5 for a film being provided with: a winding core body 1; and a tape 2 spirally attached to the outer circumferential surface of the winding core body 1. Regarding the spirally winding direction of the tape 2, portions on a first edge side and portions on a second edge side respectively from the axial center of the winding core body 1 are directed oppositely to each other, and gaps are provided between respective adjacent sections of the tape 2 attached spirally.

L’invention concerne un noyau de bobinage destiné à un film, apte à empêcher un décalage de bobinage et un rouleau de film d'alcool polyvinylique mettant en œuvre le noyau de bobinage. L’invention comprend un noyau de bobinage (5) destiné à un film qui est muni : d’un corps de noyau de bobinage (1) ; et d’une bande (2) fixée en spirale à la surface circonférentielle externe du corps de noyau de bobinage (1). Concernant le sens de bobinage en spirale de la bande (2), des parties sur un premier côté bord et des parties sur un second côté bord respectivement depuis le centre axial du corps de noyau de bobinage (1) sont orientées à l’opposé les unes des autres, et des espaces sont ménagés entre des sections adjacentes respectives de la bande (2) fixée en spirale.
(JA)
巻きずれを防止することができるフィルム用巻芯およびそれを用いたポリビニルアルコール系フィルムロールを提供するため、巻芯本体1と、この巻芯本体1の外周面に螺旋状に貼着されたテープ2とを備えた、フィルム5を巻き取るためのフィルム用巻芯であって、上記テープ2の螺旋状の巻き方向が、上記巻芯本体1の軸方向中央部から第1の端側と第2の端側とで、逆方向になっており、各螺旋状に貼着されたテープ2における隣り合うテープ2の間に、隙間が設けられるようにした。
