摘要

The paper consists of at least two layers of crepe cellulose wadding weighing 10 - 40 g/sq m, the upper layer being between 0.6 and 2 per cent longer than the lower one and embossed to form protuberances (12) in rows (14) that are joined to the lower layer to make cushions (16) of 1 - 20 sq cm in area. The cushions have a length to width ratio of preferably 1 - 1.5 : 1, and the protuberances are truncated conical in shape with bases of 1 - 1.5 mm diameter and preferably not more than 1.5 mm apart. The two-layer paper is made from two separate rolls of paper, with the upper layer taken round an embossing roller and past an adhesive application roller before the two layers are joined together and made into rolls of smaller diameter.
