<p>In a process for patterning tissue paper, e.g. for tea bags, a continuous strip of paper is embossed in the course of conversion of the strip into tissue paper products. Apparatus for converting the tissue paper into patterned product, has embossing means for embossing the strip in the course of such conversion. The invention further provides a process and apparatus for patterning tissue paper comprising subjecting the paper to the action of a heated embossing roller coated with a liquid adapted to enhance the patterned effect obtained by the embossing operation and/or the strength of the paper in the embossed area.</p> |
