    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 embossing web material such as a heated thermoplastic web material comprises first and second embossing members each having a resilient embossing surface, and means mounting the embossing members for relative movement to define a roll nip between them. The resilient surface of the first embossing member has a primary embossing pattern thereon and is of harder durometer than the resilient surface of the second embossing member. Both resilient surfaces are soft enough to be temporarily deformed in the roll nip to press the web material between them into surface conforming contact with the primary embossing pattern. The temporary deformation also helps to expel air from between the web material and the primary embossing pattern to insure surface conforming contact of the web to the embossing pattern. A secondary embossing pattern is provided on the resilient surface of the second embossing member and is of lesser depth than the primary embossing pattern. The temporary deformation assists in providing full contact with both patterns.A method of embossing the material includes heating the thermoplastic web material to a temperature within its softening range, introducing the heated material to a nip formed between the first and second embossing members, and allowing the embossed material to cool to set the pattern before removing it from the first embossing member.

    Abstract translation: 用于压花纤维网材料如加热的热塑性纤维网材料的装置包括每个具有弹性压花表面的第一和第二压花部件，以及安装用于相对运动的压花部件的装置，以在它们之间限定辊隙。 第一压花构件的弹性表面在其上具有主压花图案，并且比第二压花构件的弹性表面硬度更硬。 两个弹性表面都足够柔软，以便在辊压区中暂时变形，以将幅材材料压在它们之间以与主压花图案形成表面一致的接触。 临时变形还有助于从腹板材料和主压花图案之间排出空气，以确保幅材与压纹图案的表面一致接触。 二次压纹图案设置在第二压花构件的弹性表面上，并且具有比主压花图案更深的深度。 临时变形有助于提供与两种图案的完全接触。 将材料压花的方法包括将热塑性纤维网材料加热到其软化范围内的温度，将加热的材料引入到形成在第一和第二压花部件之间的辊隙中，并且允许压纹材料冷却以在除去之前设置图案 从第一压花构件。

    Abstract: A method for the manufacture of laminated fabrics wherein separate webs are differentially stretched and bonded in superposed relation by means of limited bondings separated by substantial unbonded regions. Thereafter the bonded webs are relaxed, whereupon one web contracts more than the other web, and the webs separate in the unbonded regions. The webs also may be individually deformed before being superposed so as to project a portion of the fibers of each web out of the plane of each web in a pattern over the entire surface area of each web and provide relatively permanently set interruptions in the planar structure of said web on at least one surface of the web for purposes of increasing the stretchable quality of the webs. The deformed webs may be superposed with surface interruptions of one web facing inwardly of the superposed webs so as to abut the other web or its surface interruptions and thus maintain the superposed webs out of intimate contact at least in the unbonded regions.
