Definitions

• the invention relates to a cylinder of a folder according to the preamble of claim 1.
• a collection cylinder is known from EP 04 36 102 A1, which has a base curve fixed to the side frame for controlling the cylinder fittings and, instead of rotatable cover disks, has electromagnetically actuated locking bolts.
• the invention has for its object to provide a cylinder of a folder.
• the switching means now used have short switching times, eg. B. of about 1/300 second.
• the cylinder fittings can be switched precisely even when the cylinder has a high peripheral speed.
• the arrangement of a stepper motor in connection with very short switching paths, in particular those generated by rotation, and the movement of small masses is advantageous. Restrictions in the switching time, switching delays that are difficult to calculate and inexact switching paths, such as may occur due to the hysteresis properties of magnetic switching devices or due to the compressibility of pressure media, are avoided.
• FIG. 1 shows a longitudinal section through a cylinder analogous to a section line I - I of FIG. 2.
• FIG. 2 shows a cross section through a cylinder analogous to section line II-II according to FIG. 1;
• Figure 3 is a schematic representation of a drive motor with switching piece and shift lever.
• Fig. 4 is a schematic representation of an embodiment of a drive motor with switching piece and shift lever.
• a cylinder 01 e.g. B. a five-part collecting cylinder 01 of a web-fed rotary printing press exists, for. B. from two possibly multi-piece side windows 02; 03, which are arranged on a shaft 04 and are possibly spaced apart from one another by cross members 06.

• Each of the cylinder fittings 07 to 11, that is to say each of the gripper systems 07 to 11, has at the end of its supporting spindle 19 a switching lever 38 which is fixed to the supporting spindle and extends approximately in the radial direction to the shaft 04.
• the shift lever 38 can run in the interior of the cylinder near the side window 02.
• the free end of the switching lever 38 can connect to a cam-like or propeller-shaped switching element 39, which can be rotated about an axis of rotation A by means of a side-plate-fixed drive motor 41.
• the switching element 39 is connected to the motor shaft of the drive motor 41 in a rotationally fixed manner.
• the drive motor 41 is preferably designed as a stepper motor 41.
• the switching piece 39 is, for. B. designed as a one- or two-armed lever 39, the free end serving the free end of the shift lever 38 as a stop and this can block (Fig. 3, 4).
• Each of the drive motors 41 assigned to the individual gripper systems 07 to 11 is connected by means of line 42; 43 with a z. B. on the outside of the side window 03 located electrical control unit 44.
