Abstract
Facetted impression elements are disclosed. The impression elements can be located, for instance, on an anvil roll and may be used during an embossing or bonding process. The impression elements include at least two chamfered surfaces that at least partially surround the top surface. The chamfered surfaces are at an angle to the top surface that lower and reduce drag that may occur between the impression element and a sheet of material as the impression element enters and exits the sheet. In one embodiment, the impression element includes a first chamfered surface having an angle of from about 5° to about 40° and a second chamfered surface having an angle of from about 40° to about 70°.
