Abstract:
A laminate having two or more plies. The plies are embossed, and adhesively joined together. The adhesive forms an essentially continuous network. The essentially continuous network increases the strength of adhesive, increases the strength of the laminate, and is disposed within the X-Y plane of the laminate coincident the embossments.
Abstract:
A method for depositing an adhesive diluted in a solvent, such as water, onto a substrate, such as a paper sheet (13) illustratively of cellulose wadding, and supported on and moving with a rotary cylinder (9) using a deposition apparatus (20) comprising at least one adhesive reservoir (23) and one cylinder transferring the adhesive onto the substrate, characterized in that the cylinder (25') does not have surface asperities and comprises first zones (25a) and second zones (25b) such that the quantity of adhesive dragged by the cylinder (25') onto the second zones is greater than the quantity of adhesive dragged onto the first zones.
Abstract:
The quality of glued nested paper towels is improved by embossing at least one of the two plies using a matched rubber embossing roll and applying adhesive to that embossed ply using a rotogravure printing roll while the ply is backed by the matched rubber embossing roll. The use of a matched rubber embossing roll reduces strength degradation of the ply during embossing and permits the use of rotogravure adhesive printing, which provides metered application of adhesive with less adhesive strike-through.
Abstract:
Method and apparatus for the manufacture of a cellular material which utilizes an embossing roller to emboss at least one film after being preheated to an embossing temperature. At least the embossed sheet preferably includes a coating of adhesive which is reactivated during the preheating procedure so that upon applying a second unheated film to the embossed film the individual embossments will be sealed. The preheating means is arranged so that it can be moved out of its normal operating position in order to enable termination of the embossing and sealing process, and means are utilized to rapidly interchange the embossing rollers to minimize the down time for the apparatus.
Abstract:
A MULTI-PLY AND TWO-SIDES PAPER TOWELING IN WHICH ONE PLY IS MORE SEVERELY EMBOSSED THAN OTHER, THE PLIES BEING PREFERABLY ADHERSIVELY ATTACHED TO FACILITATE CUTTING, ASSEMBLING AND THE LIKE WITHOUT PLY SEPARATION. THE TOWELING HAS ONE RELATIVELY ROUGH AND ONE RELATIVELY SMOOTH OUTER SIDE. A FIRST TOWELING PLY HAVING THE SMOOTH OUTER SIDE IS EMBOSSED IN SUCESSIVE ROLLING PRESSURE NIPS AND ADHESIVE MAY BE APPLIED TO EMBOSSMENT PEAKS BETWEEN PRESSURE NIPS; THE SECOND TOWELING PLY HAVING THE MORE ROUGHENED OUTER SIDE IS PREFERABLY EMBOSSED AND SIMUL-
TANEOUSLY ADHESIVELY UNITED WITH THE FIRST PLY IN THE SECOND OF THE EMBOSSING NIPS. THE LATTER OF THE EMBOSSING NIPS IS PREFERABLY, ALTHROUGH NOT NECESSARILY, A LOWER PRESSURE NIP THAN IS THE FIRST, USUALLY JUST SUFFICIENT TO SECURE ADHESION, SUCH NIP MAY BE FORMED BY THE COOPERATION OF A STEEL CONFIGURATED ROLL WITH A BACKING ROLL OF RESILIENT MATERIAL SUCH AS RUBBER OR A FINE BISTLE BRUSH.
Abstract:
An adhesively laminated creped tissue product, having particular usefulness as a dinner napkin, is formed from two creped tissue webs superposed with the lines of creping of each web substantially parallel to the lines of creping of the other, and patterned adhesive disposed between the webs. Each web is in a different condition of stress in the plane of the laminated product. The bonded webs may be formed into individual napkins embossed about their periphery, leaving a substantial unembossed area in the center.
Abstract:
A LAMINATED TISSUE PRODUCT AS FOR PAPER TOWELING IS FORMED FROM AT LEAST TWO CREPED TISSUE WEBS BONDED IN SUPERPOSED REALTION BY ADHESIVE DISPOSED IN PATTERNED LINES DELINEATING SUBSTANIAL UNBONDED REGIONS. EACH OF THE WEBS IS EMBOSSED TO PRODUCE RAISED PORTIONS EXTENDING FROM ONE SURFACE THEREOF, AND THE RAISED PORTIONS OF ONE WEB OPPOSE RESPECTIVE RAISED PORTIONS OF THE OTHER WEB. THE RAISED PORTIONS ARE EMBOSSED IN PATTERNS ASSURING OPPOSED RELATION TO THE RESPECTIVE RISED PORTIONS AND PRECLUDING ANY SUBSTANTIAL NESTING OF THE WEBS IRRESPECTIVE OF THE RELATIVE LATERAL DISPOSITION OF THE WEBS. THE WEBS ARE JOINED UNDER DIFFERENT RESPECTIVE TENSIONS SO THAT, UPON RELAXING, THE WEBS ARE IN DIFFERENT CONDITIONS OF STRESS, AND ONE WEB IS OF GREATER AREA THAN THE OTHER.
Abstract:
The disclosure of the present application relates to embossment between engraved rollers of a series or plurality of sheets of relatively heavypaper or similar matted fibrous materials to obtain varying patterns of rows of mound-like embossments which are arranged in successive areas, usually successive squares, longitudinally and then diagonally in respect to the main axis of the paper sheets. After embossment the sheets are passed through shorter or longer paths of travel before again being assembled so that their matching mounds and recesses will be offset in such a manner that they will no longer match. The disclosure further relates to the composite packing material and to a method and apparatus for making the same.
