    Abstract: The invention relates to apparatus clamping at least one paper or non-woven sheet and including two cylinders which run substantially tangent to one another. At least one of the cylinders has on its surface and in a zone that makes contact with the sheet a clamping band having first salient elements. The interaction of the two cylinders in the presence or absence of the sheet subtends an active surface during the rotation of the cylinders. In the invention, at least one of the cylinders has on its surface and in a zone (nip) that makes contact with the other cylinder by means or not of the sheet a load compensating band having second salient elements. This band is selected so that the variation of the consecutive instantaneous active surfaces of the clamping band and of the load compensating band is less than the variation of the consecutive instantaneous active surfaces of the clamping band alone. The invention applies in particular to converting paper or non-woven sheets in the manufacture of absorbent paper items, such as tissues or table napkins.

    Abstract: Adhesive is applied to a web by way of a printing plate and reverse enclosed doctor blade so as to apply the adhesive in selected locations thereby minimizing the amount of adhesive applied in order to decrease the stiffness of the resultant multi-ply web. The amount of adhesive build up on the embossing rolls due to the adhesive bleeding through the web material is minimized and the embossing rolls are permitted to clean themselves in that the adhesive application is carried out so that adhesive is not applied to the web material adjacent portions of the embossing roll on successive rotations of the roll. By doing so, portions of the backup roll which support the web where adhesive was previously applied are permitted to selfclean by allowing the adhesive which has bled through the web and collected on the backup roll to dry and flake off prior to adhesive again being applied to the web adjacent such region.

    Abstract: An embossing and laminating machine is described which comprises a first embossing cylinder (3) with a surface provided with a first set of protuberances (P3) disposed with a first pitch in a first direction (Lx3) of alignment and with a second pitch in a second direction (Ly3) of alignment, the said first and the said second direction of alignment forming between them an angle (&agr;) other then zero; a second embossing cylinder (5), with its axis (A5) parallel to the axis (A3) of the first embossing cylinder (3), and with a surface provided with a second set of protuberances (P5) disposed with the said first pitch in a third direction (Lx5) of alignment and with the said second pitch in a fourth direction (Ly5) of alignment; and a first and a second pressure roller (7, 9) interacting with the said first and the said second embossing cylinder (3, 5) respectively. The first and the third direction of alignment (Lx3) are inclined with respect to the axes (A3, A5) of the corresponding embossing cylinders (3, 5) such that, in the lamination nip, there is only partial corresponding between the protuberances of one cylinder and the protuberances of the other cylinder.

    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: 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.
