ABSTRACT:
A method for making an embossed article, tools used to make such articles and the resulting article are disclosed. The article includes a first composite element having a plurality of spaced apart subelements, which is created by mounting a first embossing tool to an embossing press wherein the first embossing tool includes first and second male dies, as well as mounting a second embossing tool in registered opposition to the first embossing tool, which includes first and second female dies complementary in number, type and position to the respective first and second male dies. After positioning a first deformable sheet material between the first and second embossing tools, the first male dies and the first female dies are compressed, the sheet is moved, and the second male dies and second female dies are compressed. Alternatively, at least some of the dies are moved or replaced prior to the second compressing actions, which may be to the same or different sheet material.
