The protuberances are in parallel lines (B1, B2, B3), forming cells (C) which are not embossed or only slightly embossed. The cells cover at least 50 % of the sheet's surface, with at least three undulating parallel rows of protuberances between adjacent cells. The cells can be divided by single lines (I) into sections embossed with at least five protuberances each
