摘要： A press roll intended, together with a press shoe, to cooperate with a counter roll to form a press with long nip for paper or board machines, said press roll comprising two end walls, a jacket, the edge portions of which are secured by an elastic clamping ring to peripheral parts of the end walls, a form-stable clamping ring being screwed to the inner side of the end-wall part to clamp the outwardly expandable elastic clamping ring so that the edge portion of the jacket is clamped firmly against a counter-support member. According to the invention each end wall includes guide means to provide a guided engagement relationship between the form-stable clamping ring and the end-wall part. The guide means includes one axially concentric guide groove in the form-stable clamping ring and an axial, concentric guide flange in the end-wall part for cooperation with the guide groove, the guide groove defining radially externally a radial clamping surface disposed opposite a corresponding clamping surface of the end-wall part for cooperating clamping of the elastic clamping ring.

摘要翻译： 一种压辊，与压力靴一起，与一个反向辊配合以形成用于纸或纸板机的长压区的压机，所述压榨辊包括两个端壁，一个夹套，其边缘部分由一个 弹性夹紧环连接到端壁的周边部分，形状稳定的夹紧环螺纹连接到端壁部分的内侧，以夹紧向外扩张的弹性夹紧环，使得护套的边缘部分牢固地夹紧 反补贴会员 根据本发明，每个端壁包括引导装置，以在形状稳定的夹紧环和端壁部分之间提供引导的接合关系。 引导装置包括形状稳定的夹紧环中的一个轴向同心的引导槽和端壁部分中的与导向槽配合的轴向同心引导凸缘，该引导槽径向向外限定径向夹紧表面， 端壁部分的夹紧表面用于协同夹紧弹性夹紧环。
