    • A method for forming a stripper roller is described where, instead of a symmetrical, cylindrical paper-feed roller, an asymmetrical feed roller (or stripper roller) is used to separate a bottommost sheet from a stack of sheets. Eccentric portions of the feed roller are located at both ends of the roller, and the middle portion of the roller is cylindrical. In one embodiment, the eccentric end portions are formed by cutting ends of a cylindrical roller and then placing a shim between the center shaft and each end portion. Paper-feed springs oppose the eccentric portions of the feed roller, while a centrally located separator pad opposes the cylindrical middle portion of the feed roller. The extended radius at the apogee of the eccentric portions allows the eccentric portions to effectively reach out and grab the bottommost sheet even if the stack of sheets were only initially lightly contacting the roller. The eccentric portions of the feed roller also provide surges in the frictional force urging the bottommost sheets toward the separator pad. This surge in force acts to spread out (or pre-separate) the paper in the stack so the paper can be more easily separated by the separator pad.
    • 描述了形成剥离辊的方法,其中代替对称的圆柱形进纸辊,使用不对称的进料辊(或剥离辊)将最底层的纸张与一叠纸张分开。 进料辊的偏心部分位于辊的两端,辊的中间部分是圆柱形的。 在一个实施例中,偏心端部通过切割圆柱形辊的端部然后将垫片放置在中心轴和每个端部之间而形成。 送纸弹簧与进给辊的偏心部分相对,而位于中心的分隔垫与进给辊的圆柱形中间部分相对。 在偏心部分的远地点处的延伸半径允许偏心部分有效地伸出并抓住最底部的片材,即使一叠片材最初仅轻轻地接触辊子。 进给辊的偏心部分也提供了将最下面的薄片推向分隔垫的摩擦力的浪涌。 这种浪涌作用用于将纸张分散(或预分离)在堆叠中,使得纸张可以更容易地被分离器垫分离。
