    Abstract: The present invention is directed to an apparatus which is suited for use by women, children and the like who have limited physical strength to continuously stamp embossed patterns with clear outlines with the same spacing. A press roller is provided with an embossed pattern stamping die on a circular external circumferential surface, with its rotating shaft supported by bearings at a specific position, and is caused to perform axial rotation by a rotating drive force applied from the outside. A receptacle portion faces opposite the external circumferential surface of the press roller, with its opposing surface constituted as a flat surface or a convex surface to form a gap between itself and the press roller where a sheet-like object to be stamped is to be inserted.

    Abstract: An extensible multi-ply tissue paper product having high tensile energy absorption (TEA); high liquid absorbency; and, preferably, high tensile strength efficiency. The product comprises plies which are preferably embossed and discontinuously adhered together. The product has high tensile energy absorption by virtue of having substantial extensibility in the machine direction which, preferably, results from its constituent plies having substantial MD extensibility induced by having undergone wet and/or dry foreshortening during their manufacture. The product has synergistically high liquid absorbency by virtue of at least two plies of the product having sufficiently different stress/strain properties that one ply will sufficiently constrain unadhered portions of the other ply from being elongated in the plane of the paper when wetted that such unadhered portions of the constrained ply will pucker in the Z-direction as its foreshortening-induced internal stresses are relieved. Preferably, the constraining ply is high bulk, wet-microcontracted tissue paper, and the other ply is dry-foreshortened tissue paper: e.g., dry-creped tissue paper. Also, the plies of preferred embodiments preferably have nominally equal MD extensibilities at rupture. Such preferred products have high tensile strength efficiency which is manifested by their having monomodal stress/strain characters. Embodiments of the invention such as two and three ply paper towels are especially useful for spill wipe-up applications.

    Abstract: Absorbent paper sheets in multi-ply web form in which the outer webs of the sheet are creped and consist of a series of ribs and grooves. The webs have their ribs secured together by adhesive dispersed in a pattern consisting of individual adhesive zones. The adhesive zones are obtained by providing in embossing apparatus cooperable rolls each having alternating ribs and grooves, the ribs of one roll being provided with protuberances and the other with recesses. The protuberances cover a relatively small area of the total rib area and carry a web on the protuberances through an adhesive applicator so that a relatively small area of the web receives adhesive for attachment to a second web.

    Abstract translation: 多层腹板形式的吸收性纸张，其中片材的外部网片起皱并且由一系列肋条和凹槽组成。 网状物的肋骨通过分散在由各个粘合剂区域组成的图案中的粘合剂固定在一起。 粘合剂区域通过在压花设备中提供具有交替的肋和凹槽的配合的辊来获得，一个辊的肋设置有突起，而另一个具有凹槽。 突起覆盖总肋面积的相对较小的区域，并通过粘合剂施加器将纤维网带在突起上，使得幅材的相对较小的区域接收用于附接到第二幅材的粘合剂。
