Abstract:
기부 시트를 가열 엠보싱하는 방법 및/또는 종이 제품의 여러겹을 함께 천공하고 접착하는 방법이다. 이 방법은 종이 제품에 장식 패턴을 인가하기 위해 그리고/또는 여러겹 제품을 접착하기 위해 사용된다. 일실시예에서, 본 발명의 방법은 미리 형성된 홑겹 또는 여러겹의 기부 시트를 가열된 엠보싱 닙을 통해 공급하는 단계를 포함한다. 기부 시트가 가열된 엠보싱 닙을 통과할 때, 충분한 열과 압력이 인가되어 시트 내의 섬유들이 용융 또는 글라신지화되기 시작한다. 냉각되면, 내부 섬유 결합으로 여러겹 제품의 겹들 사이에서 접착이 일어날 뿐만 아니라 엠보싱이 잘 형성된다.
Abstract:
The present disclosure is directed to a paper towel product that will capably separate from the paper towel roll as a full sheet, a half sheet or a quarter sheet. A method of making a paper towel with machine direction perforations is also disclosed.
Abstract:
Methods and apparatuses for deforming a web are disclosed. In one embodiment, the method involves feeding a web into a nip that is formed between at least two intermeshing rolls. The rolls are configured for deforming a web with at least two sets of deformations that are oriented in different directions relative to the surfaces of the web.

Abstract:
A method for making apertures in a web comprising providing a precursor web material; providing a pair of counter-rotating, intermeshing rollers, wherein a first roller comprises circumferentially-extending ridges and grooves, and a second roller comprises teeth being tapered from a base and a tip, the teeth being joined to the second roller at the base, the base of the tooth having a cross-sectional length dimension greater than a cross-sectional width dimension; and moving the web material through a nip of the counter-rotating, intermeshing rollers; wherein apertures are formed in the precursor web material as the teeth on one of the rollers intermesh with grooves on the other of the rollers.
Abstract:
Method of manufacturing a hygiene paper product in form of a continuous paper web (W)of sheets partly separated by perforation lines (9) and wound to a log of predetermined longitudinal length, providing a continuous paper web (W), moving the continuous paper web in a direction of its longitudinal extension, providing at least one embossed pattern on the continuous paper web, providing in the area of an embossing station at least one mark (6, 7) onto the continuous paper web, which mark (6, 7) is in register to the embossed pattern, sensing the mark and controlling perforating means for registering the perforation lines (9) with the embossed pattern thereby imparting perforation lines to the continuous paper web in predetermined longitudinal distances, winding up the resulting web to logs, and cutting the log into rolls.
Abstract:
Apparatuses and processes for aperturing and stretching a web are disclosed. In one embodiment, the method involves feeding a web into a nip that is formed between at least one pair of intermeshing rolls. The first roll is a raised ridge rotary knife aperturing roll and the second roll is a ring roll; both rolls comprise ridges and grooves. The first roll comprises a plurality of spaced-apart teeth extending outwardly from the top surface of the ridges, said teeth having tips, wherein the top surface of said ridges are disposed between the tips of said teeth and the bottom surface of said grooves. These apparatuses and processes enable a web to be formed which comprises apertures having greater open area than previously achievable with traditional processes and apparatuses.
Abstract:
Absorbent members and methods of making the same are disclosed. In one embodiment, the absorbent member is a unitary absorbent fibrous web having a density profile through its thickness. In one embodiment, the density profile of the fibrous web is skewed toward one of the surfaces of the fibrous web. In such embodiments, the maximum density of the web may be located outside of the central 30% zone of the thickness of the web. In one embodiment, the method involves subjecting a precursor web to at least one cycle (or pass) through a mechanical deformation process. Typically, the method involves subjecting the precursor web to multiples cycles (or passes) through a mechanical deformation process.
Abstract:
An embossing system for embossing and perforating at least a portion of a web is provided comprising a first embossing roll having embossing elements and at least a second embossing roll having embossing elements, wherein the elements of the first and second embossing rolls define perforate nips for embossing and perforating the web and wherein at least a predominate number of the perforate nips are substantially oriented in the cross-machine direction. Moreover, substantially all of the nips defined by the embossing elements of the first and second embossing rolls can be substantially oriented in the cross-machine direction. Further, the cross-machine embossing elements are at an angle of about 85° to 95° from the machine direction.
