Abstract

Cette invention se rapporte à un procédé de fabrication de papier ayant moins tendance à produire des coupures de la peau. Ce procédé consiste à former une couche fibreuse de pâte à papier, contenant des fibres de cellulose et environ 0,5 à environ 5,0 % en poids de microsphères expansibles, calculés sur la base du poids à sec, à produire une bande de carton à partir de cette couche fibreuse de pâte à papier, à sécher cette bande et à effectuer le calandrage de cette bande à un calibre compris entre environ 11,0 et environ 18,0 mils et une densité comprise entre environ 7,0 et environ 12,0 livres/3000 pieds?2¿/mil. Les papiers produits selon ce procédé et les articles fabriqués avec ce papier sont également décrits.
