    • A multi-ply tissue includes a first cellulosic embossed ply having an emboss pattern applied over a portion of its surface and a second cellulosic embossed ply of tissue. The first ply is contact laminated to the second ply so that the primary adhesion between the plies of tissue is the result of contact between cellulosic fibers. The first and second plies contact one another in contact-areas, with the contact areas between the first and second plies defining compliant voids. The contact areas between the first ply and the second ply are elongated and/or rounded contact areas. A method of forming a multi-ply tissue involves conveying a base sheet through a nip between an impression roll and a pattern roll to produce an embossed base sheet having a back side possessing projections, applying adhesive to the back side of the embossed base sheet at spaced apart locations, and applying a flat backing sheet to the back side of the embossed base sheet so that the backing sheet adheres to the back side of the embossed base sheet at said spaced apart locations. A method of producing an embossed tissue involves successively conveying a base sheet through a nip between a first impression roll and a pattern roll, and conveying the base sheet through another nip between the pattern roll and a second impression roll, wherein the second impression roll is made of rubber having a lower hardness than the rubber from which the first impression roll is made.
    • 多层组织包括具有施加在其表面的一部分上的压花图案的第一纤维素压纹层和第二纤维素压花的纸巾层。 第一层被层压到第二层上,使得组织层之间的主要粘附是纤维素纤维之间的接触的结果。 第一层和第二层在接触区域彼此接触,第一层和第二层之间的接触面定义合适的空隙。 第一层和第二层之间的接触区域是细长的和/或圆形的接触区域。 形成多层组织的方法涉及将基片材输送到压印辊和图案辊之间的辊隙,以产生具有背面具有凸起的压花基片,并将粘合剂施加到压花基片的背面 间隔开的位置,并且将平的背衬片施加到压花基片的背面,使得背衬片在所述间隔开的位置处粘附到压花基片的背面。 制造压纹组织的方法包括依次将基片通过第一压印辊和图案辊之间的辊隙传送,并且将基片通过图案辊和第二压印辊之间的另一个辊隙输送,其中第二压印辊 由比制成第一压印辊的橡胶硬度低的橡胶制成。
