Title
(EN) SHEET FOR SUCTION FIXING
(FR) FEUILLE POUR FIXATION PAR ASPIRATION
(JA) 吸着固定用シート
Abstract
(EN)
The present disclosure provides a sheet for suction fixing that is disposed on a suction surface of a suction device so as to prevent contact of an article being suctioned with the suction surface, wherein: the sheet for suction fixing is provided with a porous sheet having air permeability in the direction of thickness, and a two-sided adhesive sheet disposed on one surface of the porous sheet, having a base material, and having air permeability in the direction of thickness or a two-sided adhesive layer disposed on one surface of the porous sheet, formed from a cross-linked adhesive, having air permeability in the direction of thickness, and having no base material; and the ratio of the thickness of the porous sheet to the thickness of the two-sided adhesive sheet or the two-sided adhesive layer is 8.0 or greater. With the sheet for suction fixing according to the present disclosure, unintended deformation or damage to the surface of an article being suctioned does not occur easily even when the surface area of this sheet is made large or this sheet is used at high temperatures.
(FR)
La présente invention concerne une feuille pour fixation par aspiration qui est disposée sur une surface d'aspiration d'un dispositif d'aspiration de façon à empêcher le contact d'un article qui est aspiré avec la surface d'aspiration : la feuille pour la fixation par aspiration étant pourvue d'une feuille poreuse présentant une perméabilité à l'air dans la direction d'épaisseur et une feuille adhésive double face disposée sur une surface de la feuille poreuse, présentant un matériau de base et présentant une perméabilité à l'air dans la direction d'épaisseur ou une couche adhésive double face disposée sur une surface de la feuille poreuse, formée à partir d'un adhésif réticulé, présentant une perméabilité à l'air dans la direction d'épaisseur et ne présentant pas de matériau de base ; et le rapport de l'épaisseur de la feuille poreuse à l'épaisseur de la feuille adhésive double face ou de la couche adhésive double face étant de 8,0 ou plus. Grâce à la feuille pour fixation par aspiration selon la présente invention, une déformation ou une détérioration involontaires de la surface d'un article qui est aspiré ne se produit pas facilement, même lorsque l'aire de surface de cette feuille est grande ou lorsque cette feuille est utilisée à des températures élevées.
