Abstract:
A method of producing water-disintegrable paper, including: using a base-paper supplied with no water to emboss the base-paper sheet in a non-wet state to form a bulking unit, made up of a plurality of uneven elements, on the base-paper sheet; supplying the water-soluble binder to the base-paper sheet from outside of a face of the base-paper sheet after the embossing process to impregnate the water-soluble binder into the base-paper sheet; drying the base-paper sheet after the binder impregnation process; folding the base-paper sheet after the drying process; and supplying an aqueous chemical and/or a crosslinker to the base-paper sheet before or after the folding process to impregnate the aqueous chemical into the base-paper sheet.

Abstract:
An apparatus (1) and method for producing embossed paper or laminated metallic foil sheets (55) comprising means for feeding an elongate strip (20) of paper or laminated metallic foil, a pair of matched embossing rollers (5, 10) disposed to receive such a strip from the feeding means, and means for receiving such a strip from the embossing rollers after being embossed thereby, and for cutting such strip into sheets. The rollers have a plurality of embossing sectors (75) arranged on the surface thereof. At least one of the sectors imparts a first embossing, and at least another of the sectors imparts an alternate embossing different in appearance from the first embossing. The sectors are dimensioned similarly to the foil sheets. At least one group of the sheets carry the first embossing while at least another group of the sheets carry the alternate embossing.
