摘要： An apparatus for the production of a fibrous web, especially a tissue or hygienic web, the fibrous web runs through a press nip which is formed by a press unit and a backing roll and the web is subsequently run through a creping nip which is formed by the backing roll and a creping roll around which a textured belt is looped. Moreover, the creping roll is equipped with its own drive. The creping roll can be pressed against the backing roll through a pivoted lever whose pivoting axis which is parallel with the axes of the creping roll and is positioned such that the connecting line between the pivoting axis and the creping roll axis forms an angle of approximately 90° with the connecting line between the creping roll axis and the backing roll axis, when viewed in a vertical plane relative to these axes.

摘要： A belt (10) for shoe press comprising a shoe side layer (20), a substrate (30) formed on the our circumference of the shoe side layer (20), and a wet paper side layer (60) formed on the outer circumference of the substrate (30). The substrate (30) consists of a lattice-like material (40) formed by bonding the intersection of a warp (40A) and a weft (40B), and a thread winding layer (50) formed by winding a thread (50A) spirally. Bonding at the intersection of the warp (40A) and the weft (40B) is separated easily and friction takes place between them, but since the warp (40A) is made to wear earlier than the weft (40B), the weft (40B) does not wear in the early stage as compared with prior art. Consequently, strength and dimensional stability of the belt for shoe press are enhanced.
摘要翻译：一种用于靴式压榨机的带（10），包括鞋侧层（20），形成在鞋侧层（20）的我们的圆周上的基底（30）和形成在外圆周上的湿纸侧层的基板（30）。衬底（30）由通过粘合经线（40A）和纬纱（40B）的交点形成的格子状材料（40）和螺旋缠绕线（50A）形成的线缠绕层（50）。在经纱（40A）和纬纱（40B）的交点处的接合被容易地分离，并且在它们之间发生摩擦，但是由于经线（40A）比纬纱（40B）更早地磨损，所以纬纱（40B）与现有技术相比，在早期阶段不磨损。因此，鞋带的带的强度和尺寸稳定性得到提高。
