<p>The present invention provides an apparatus and method of embossing a sheet (18) of material with a background pattern together with additional selectable indicia (80), wherein the method comprises the steps of removably securing an indicia bearing element (80) to a first one (34) of embossing rollers (34, 36), and removably securing a yielding element (142) to a second one (36) of embossing rollers (34, 36) passing the sheet material (18) through the nip (38) of rigid embossing rollers (34, 36) while synchronously moving the embossing rollers (34, 36), so as to impart a background embossed pattern to a first portion of the sheet material (18), and secondly imparting additional indicia to second portions of the sheet material by repetitively bringing into opposing relationship at the nip (38) the indicia bearing element (80), and the yielding element (142).</p> |
