When making multi ply toilet tissue, the plies of tissue are usually split and each ply is passed through a different embossing roller. Embossing softens the toilet tissue and creates a decorative pattern. The tissue plies are brought back together then held together with glue or pressure embossing, the tissue is then perforated by blade, (this enables the sheets to be easily pulled apart). The tissue is then wound around a cardboard tube to create a long toilet roll the length of 23 to 25 individual toilet rolls, which are called logs.
