Abstract: Embossing a web between unmatched male and female embossing elements, wherein the sidewall slope of the female element is different than the sidewall slope of the male element, provides an embossed web having markedly improved embossing pattern definition and, in the case of roll products, greater roll bulk at equivalent roll firmness. The unmatched male and female embossing elements are preferably made by laser engraving rubber embossing rolls.

Abstract: A method is provided for thermoforming thermoplastic foam articles whereby the tendency for such articles to deform and/or warp immediately upon release from the thermoforming device is eliminated. The method includes the formation of parallel or concentric grooves on one surface of the article during the course of the thermoforming operation. Such grooves eliminate the pronounced tendency of thermoformed articles to curl up following their removal from the thermoforming mold and maintains the formed piece in the desired flat configuration.

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.
