Abstract
An embossed tipping paper includes a relief pattern region having a patterned embossing structure formed in the depth of the material of the tipping paper. The embossed tipping paper further includes at least one plain region adjacent to the relief pattern region, the at least one plain region not having an embossing structure formed in the depth of the material of the tipping paper. A sequence of ventilation holes is formed in the at least one plain region. The embossed tipping paper has a substantially rectangular shape and the at least one plain region forms a band of fixed width running between two parallel edges of the substantially rectangular shape.
Claims18
An embossed tipping paper for use in smoking articles, the tipping paper comprising:
- a relief pattern region having a patterned embossing structure formed in a depth of a material of the tipping paper;
- and
- at least one plain region adjacent to the relief pattern region, the at least one plain region not having an embossing structure formed in the depth of the material of the tipping paper, and a sequence of ventilation holes being formed in the at least one plain region,
- wherein the embossed tipping paper has a substantially rectangular shape, the at least one plain region forming a band of fixed width running between two parallel edges of the substantially rectangular shape.
An embossing roller used for embossing tipping paper for smoking articles, the embossing roller comprising:
- an engraving pattern on a roller surface, the engraving pattern configured to form a relief pattern region having a patterned embossing structure in a depth of a material of the tipping paper;
- and
- at least one plain area on the roller surface adjacent to the engraving pattern, the at least one plain area configured to form at least one plain region adjacent to the relief pattern region, the at least one plain region not having an embossing structure formed in the depth of the material of the tipping paper,
- wherein the at least one plain area forms a band of fixed width running through the engraving pattern in parallel to a circumference of the embossing roller.
A method of manufacturing smoking articles with embossed tipping paper, comprising the steps of:
- forming a patterned embossing structure in a depth of a material of the tipping paper to form a relief pattern region;
- omitting at least one plain region adjacent to the relief pattern region during formation of the patterned embossing structure in the depth of the material of the tipping paper, so that the tipping paper includes the relief pattern region with the patterned embossing structure and the at least one plain region not having a patterned embossing structure;
- and
- forming a sequence of ventilation holes in the at least one plain region of the tipping paper,
- wherein the embossed tipping paper has a substantially rectangular shape, the at least one plain region forming a band of fixed width running between two parallel edges of the substantially rectangular shape.
