发明名称 Apparatus and methodology for embossing fibrous webs containing contaminants
摘要 Apparatus and methodology to provide embossing of recycled pulp, which may contain contaminants such as glue or paper particles, without adversely affecting the processing machinery. This enables the recycled pulp to be embossed in a manner similar to that of non-recycled pulp which provides an absorbency, softness and appearance to the finished product which compares favorably to paper products made from non-recycled pulp. The embossing is carried out by matched embossing rollers in which one of the rollers is relatively soft (Shore A hardness of 40-65) and the other roller is relatively hard (Shore A hardness above 90). Recycled pulp, even containing contaminants, may be embossed in this manner without causing excess wear or possible damage to the embossing rollers.
