    Abstract: An improved system for embossing a pattern on an absorbent consumer paper product such as a paper towel includes a first pair of embossing rollers that are patterned to impress a relatively fine preparatory base pattern onto the web, and a second pair of embossing rollers that are patterned to impress a final pattern onto the web. The final pattern is of a type that would cause bursting of the absorbent paper web if the absorbent paper web was passed through the second pair of embossing rollers without first being passed through the first set of embossing rollers. As a result, the formation of the preparatory base pattern by the first set of embossing rollers creates stretchability in the absorbent paper web that enables the final pattern to be impressed thereon by the second pair of embossing rollers without bursting the absorbent paper web.

    Abstract translation: 用于在诸如纸巾的吸收性消费纸产品上压花图案的改进系统包括第一对压花辊，其被图案化以将相对精细的预备基底图案压印到幅材上，以及第二对图案化的压花辊 将最终的图案印在网上。 如果吸收性纸幅通过第二对压花辊而不首先通过第一组压花辊，则最终图案是会引起吸收性纸幅破裂的类型。 结果，通过第一组压花辊形成准备基底图案，在吸收性纸幅上形成拉伸性，使得最终图案能够被第二对压花辊压印在其上，而不会使吸收性纸幅断裂。

    Abstract: A method of embossing a sheet of non-woven fibrous web, e.g. toilet tissue, with a series of identical boss elements arranged in a uniform pattern in a manner to avoid nesting of the embossments and resulting non-uniform product rolls when the sheet is rolled onto a mandrel. The embossments are uniformly spaced in rows which in the longitudinal direction form an angle in the range of 15.degree. to 23.degree. relative to the edge of the sheet or roll and an angle in the range of 40.degree. to 57.degree. relative to the cross direction of the sheet or roll.

    Abstract: Apparatus for applying a continuous embossing pattern to webs of material such as paper or the like and a method for producing an embossing surface. The apparatus includes rollers which receive a web or webs of such material therebetween and removable embossing plates secured to the surface of the rollers and having an embossing surface for embossing the webs. The rollers are constructed such that they have magnetic properties whereby the embossing plates which are comprised of magnetically attracted material can be held against the roller surface. The plates are positioned in closely adjacent relationship with respect to each other such that they provide a continuous embossing pattern around the surface of the roller. The plates and the rollers also include mutually engaging registering means which permit the plates to be accurately aligned with respect to the roller surface. The plates can thus be readily removed or replaced in the event that they become worn or damaged or in the event that it is desirable to change the embossing pattern frequently. The embossing pattern can be formed in the surface of each of the embossing plates by means of a method of coating the plate surfaces with a photo-chemical resist material, laying a negative of the desired pattern over the photo-chemical coating, directing light through the negative to cause selective deterioration of the coating, and subjecting the plate to a caustic chemical, wash chemical, or etchant to etch the desired pattern into the surface of the plate. The plate may, if necessary, be further machined in order to increase the depth of the etching and to improve the definition and clarity of the embossing pattern.

    Abstract translation: 用于将连续压花图案施加到诸如纸或类似材料的纸幅的装置以及用于生产压花表面的方法。 该装置包括在其间容纳这种材料的腹板或腹板的辊，以及固定到辊的​​表面的可移除的压花板，并具有用于压花腹板的压花表面。 辊被构造成使得它们具有磁性，由此由磁吸引材料构成的压花板可以抵靠辊表面保持。 板相对于彼此定位成紧密的关系，使得它们围绕辊的表面提供连续的压花图案。 板和辊也包括相互接合的配准装置，其允许板相对于辊表面精确对准。 因此，如果它们变得磨损或损坏，或者希望经常改变压花图案，则可以容易地移除或更换板。 压花图案可以通过用光致抗蚀剂材料涂覆板表面的方法形成在每个压花板的表面中，在光化学涂层上铺设所需图案的负片，将光引导通过 导致涂层的选择性劣化的负面，以及对板进行苛性化学品，洗涤化学品或蚀刻剂以将期望的图案蚀刻到板的表面中。 如果需要，可以进一步加工板以增加蚀刻的深度并提高压花图案的清晰度和清晰度。

    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。
