Abstract:
A desirable embossing of a fibrous web (6) as dry laid on a forming sheet (2) is effected by the web (6) in a still unglued condition passing a pair of embossing producing rollers (18, 20) carried on or by a pressure resistant support sheet (16) as also passing between the rollers. Problems as to web fractures are hereby widely eliminated.
Abstract:
To provide a method of producing water-disintegrable paper capable of addressing a disadvantage of adhesion of a base-paper sheet to an embossing apparatus when the base-paper sheet impregnated with a water-soluble binder is embossed, achieving simple manufacturing and low manufacturing cost, and minimizing the likelihood of paper powder remaining on a dry surface of a cleaned object after use. To produce water-disintegrable paper, a base-paper sheet 2 in a non-wet state before a water-soluble binder is impregnated is embossed in order to form a bulking unit 17, made up of a plurality of uneven elements 12, on the base-paper sheet 2; a water-soluble binder solution 5 is sprayed to the base-paper sheet 2 having the bulking unit 17 formed, from outside of a face of the base-paper sheet 2 to impregnate the water-soluble binder solution 5 into the base-paper sheet 2; the base-paper sheet 2 impregnated with the water-soluble binder solution 5 is dried; the base-paper sheet 2 is folded after the drying; and an aqueous chemical solution is sprayed to the base-paper sheet 2 thus being folded to impregnate the aqueous chemical solution into the base-paper sheet 2.

Abstract:
On effectue le gaufrage d'une bande fibreuse (6) vergée sèche sur une feuille de formation (2) en faisant passer la bande (6) lorsqu'elle est encore non collée par une paire de cylindres de production de gaufrage (18, 20) portés sur ou par une feuille de support (16) résistant à la pression et en la faisant passer entre les cylindres. Des problèmes comme des ruptures de la bande sont ainsi géneralement éliminés.
Abstract:
A laminating unit (1) or joining two or more plies for producing paper items, comprising a plurality of knurling tools (3) adapted to act on a contrast roller (2) to join two or more plies arranged between the contrast roller (2) and the knurling tools (3); each knurling tool (3) is constituted by a roller having a smaller longitudinal dimensions than the contrast roller (2); the unit (1) comprises a flexible pressure tube (4) that extends longitudinally along a first supporting beam (5) which supports the flexible pressure tube (4) so as to press the knurling tools (3) onto the contrast roller (2) when the flexible tube (4) is inflated by means of a pressure fluid; the knurling tools (3) are mounted on a second beam (8) by means of oscillating bearings (7).
Abstract:
The present invention refers to an embossed composite nonwoven web material comprising a mixture of thermally unbonded continuous spunlaid filaments and short fibers comprising natural and/or synthetic fibers or staple fibers, the continuous filaments and short fibers being substantially mechanically bonded to each other by hydroentangling and the composite nonwoven web material is embossed without thermobonds to have a strength index equal to or more than 1 time the strength index of the unembossed composite nonwoven web material.
Abstract:
An emboss device (1) includes an emboss roller (15) having a surface on which convexoconcave are formed; an opposed roller (16) arranged oppositely to the emboss roller (15). The emboss roller 15 and the opposed roller 16 sandwich a sheet-like print object 2, thereby to impart convexoconcave to the print object (2). The spacing d between the protruded part of the surface of the emboss roller 15 and the surface of the opposed roller (16) is set to 50 µm to 200 µm.
