15. A high speed embossing and adhesive printing process, said process comprising the steps of:
-
(a) supplying a first embossing roll whose surface comprises a material and having a first embossing pattern disposed thereon, wherein said first embossing roll is engaged with a second embossing roll, said second embossing roll having a second embossing pattern disposed thereon, said first embossing pattern and said second embossing pattern being complementary, wherein said material of the first embossing roll comprises a polymer and has a Shore A hardness of greater than about 70, and has a critical surface energy of less than about 30 dynes/cm;
(b) applying said adhesive to said first embossing roll; and
(c) passing a substrate of sheet material between said first and second embossing rolls to simultaneously emboss said substrate thereby forming a pattern of valleys and land areas and apply said adhesive to said substrate, such that said adhesive forms an adhesive pattern on said valleys between said land areas. - View Dependent Claims (16, 17, 18, 19)

20. A method for embossing and applying an adhesive to a substrate comprising
(a) supplying a first embossing roll whose surface comprises a material and having a first embossing pattern disposed thereon, wherein said first embossing roll is engaged with a second embossing roll, said second embossing roll having a second embossing pattern disposed thereon, said first embossing pattern and said second embossing pattern being complementary, wherein said embossment material comprises a polymer and has a Shore A hardness of greater than about 70, and has a critical surface energy of less than about 30 dynes/cm; -
(b) applying an adhesive to said first embossing roll;
(c) contacting a substrate of sheet material with said first embossing roll after step (b), whereby said adhesive forms an adhesive pattern on said substrate of sheet material in register with said first embossing pattern of said first embossing roll; and
,(d) passing said substrate of sheet material between said first embossing roll and said second embossing roll wherein said first embossing roll and said second embossing roll emboss said substrate with said complementary embossing pattern thereby forming a pattern of valleys and land areas such that said adhesive pattern is on said valleys between said land areas. - View Dependent Claims (21)
