摘要 |
A support member such as a belt or sleeve includes a topographical pattern on its sheet contact side. A plurality of land areas, corresponding depressions, through voids, and/or groove areas are formed on the top surface of the support member to produce the topographical pattern. The land areas, corresponding depressions, through voids, and/or groove areas may be formed by graving, cutting, etching, embossing, mechanical perforation or a combination thereof. The improved belt or sleeve imparts desired physical characteristics, such as bulk, appearance, texture, absorbency, strength, and hand to a nonwoven product produced thereon. |
