    摘要： A self-centering roll includes a body, a first layer of rubber surrounding the body, and a second layer of rubber surrounding the first layer, the rubber on the first layer being softer and of lower density than the rubber in the second layer. Flexible projections are formed in the second layer of rubber on each side of the transverse center of the roll extending outwardly from the roll body toward the transverse center of the roll.

    摘要： A self-centering roll for tracking webs includes a shaft, an end web secured to the shaft adjacent each end, and a tubular rim section secured to each end web and arranged with a space between their adjacent ends sufficient to permit deflection of these adjacent ends toward the shaft. Each of the end webs includes a compressible member, such as rubber, for transmitting a load from the rim portion to the shaft. It is preferred to use a central web including a compressible member for transmitting load from the rim portions to the shaft and to have the space within the roll entirely enclosed.

    摘要： A rotating sleeve coaxially mounted upon an inner nonrotating pivoting sleeve by at least two rotary bearings on either side of a center mounted pivoting bearing assembly within the nonrotating pivoting sleeve supported by a stationary shaft. The nonrotating pivoting sleeve is balance-mounted in the center of the axis shaft with the pivoting bearing assembly. The pivoting bearing assembly permits a selected degree of lateral rotation in a range of from about 1 degree to about 10 degrees. As a web runs over the rotating sleeve any imbalance of lateral tension will cause the nonrotating pivoting sleeve to pivot at it's center with respect to the longitudinal axis of the shaft permitting the nonrotating pivoting sleeve and coaxial rotating sleeve to pivot upward on the side of least tension until the web tension is equalized across the coaxial rotating sleeve.

    摘要： A self-centering roll has two tubular end rim portions mounted on a straight shaft by means of a deflectible end web connected to the outer end of each end rim portion. Each end web includes a bearing mounted on the shaft and a compressible member extending between and connected to the bearing and associated rim portion. An inner web mounted on the shaft adjacent the inner end of each end rim portion includes an eccentric hub, bearings mounted on the eccentric hub and a member eccentric with respect to the shaft axis mounted on the outside of the bearing concentric with the bearing axis. The eccentricities of the inner webs are the same so that the rim portions rotate on axes that intersect at a point between the inner webs and are arranged at the same angle to the shaft axis. In one embodiment the end rim portions are arranged with a slight space between their adjacent ends. In a second embodiment the end rim portions are separated by a large space and a central tubular rim portion is positioned therebetween with a slight space between each end of the central rim portion and the associated end rim portion. The central rim portion is mounted on the shaft by means of webs similar to the inner webs with its axis offset but parallel to the shaft axis. A connecting web is preferably connected to the rim portions spanning the slight space between adjacent rim portions. The connecting web includes a bearing surrounding the shaft and a central compressible member extending between the adjacent rim portions. A peripheral slot is provided in the compressible member in alignment with the slight space between the rim portions.

    摘要翻译： 自定心辊具有通过连接到每个端部边缘部分的外端的可偏转端部腹板而安装在直轴上的两个管状端部边缘部分。 每个端网包括安装在轴上的轴承和在轴承和相关联的边缘部分之间延伸并连接到轴承和相关联的边缘部分的可压缩构件。 安装在相邻于每个端缘部分的内端的轴上的内腹板包括偏心轮毂，安装在偏心轮毂上的轴承和相对于安装在与轴承轴线同心的轴承的外侧上的轴线偏心的构件。 内腹板的偏心度相同，使得边缘部分在与内腹板之间的点相交的轴线上旋转并且以与轴线成相同的角度布置。 在一个实施例中，端部边缘部分在其相邻端部之间布置有微小的空间。 在第二实施例中，端部边缘部分被大的间隔分开，并且中心管状边缘部分位于它们之间，在中心边缘部分的各个端部和相关联的端部边缘部分之间具有小的空间。 中心边缘部分通过类似于内部腹板的腹板安装在轴上，其轴线偏移但平行于轴线。 连接腹板优选地连接到跨越相邻边缘部分之间的微小空间的边缘部分。 连接腹板包括围绕轴的轴承和在相邻轮缘部分之间延伸的中心可压缩构件。 在可压缩构件中设置有与边缘部分之间的微小空间对准的外围槽。
