    • A folding cylinder includes a plurality of gripping devices supported on a first rotatable support with a first gripping device for holding a signature on the cylinder. A plurality of tucking devices are supported on a second rotatable support, the tucking devices including a first tucking device and a second tucking device. The first gripping device is located circumferentially between the first tucking device and second tucking device and a cover fixed to the second rotatable support extends circumferentially over the first gripping device between the first tucking device and the second tucking device. The cover has at least one aperture, with the first gripping device capable of extending through the at least one aperture. With the folding cylinder of the invention gaps between the tucking and gripping spiders can be eliminated.
    • 折叠圆筒包括支撑在第一可旋转支撑件上的多个夹持装置,其具有用于将标记保持在圆筒上的第一夹持装置。 多个卷起装置被支撑在第二可旋转支撑件上,所述卷起装置包括第一卷起装置和第二卷起装置。 第一夹持装置位于第一收紧装置和第二折回装置之间周向地定位,并且固定到第二可旋转支撑件的盖在第一收紧装置和第二折回装置之间的第一夹持装置周向延伸。 所述盖具有至少一个孔,其中所述第一夹持装置能够延伸穿过所述至少一个孔。 利用本发明的折叠圆筒可以消除折叠和夹紧蜘蛛之间的间隙。
