  • a sleeve of a support arrangement is rotatably mounted on a shaft projecting from a transportable frame in the horizontal direction.
  • Three radially protruding support arms are attached to this sleeve.
  • One of these support arms is provided with a retractable and extendable support.
  • a hollow cylindrical winding core the outer side of which is intended to carry a winding of printed products, is placed with the inner, cylindrical side onto the other two support arms when the support is retracted. By extending the support, the winding core is releasably clamped to the support arrangement.
  • Another device for supporting a hollow cylindrical winding core is known for example from EP-OS 0 161 569 or the corresponding US-A-4,601,436.
  • the support arrangement of this device has two parallel-axis support wheels which are rotatably and drivably mounted on a frame.
  • the two support wheels are parts of a friction gear, to which a further ring-shaped friction wheel belongs, which is also a winding core, on which printed products are wound together with a winding belt.
  • the inner surface of the winding core comes to rest on the two support wheels and serves as a running surface, which is laterally delimited by inwardly projecting side flanges.
  • a winding core is known from EP-OS 0 236 561, which has an outer surface on its outside for carrying a winding of printed products.
  • the printed products are wound together with a winding tape attached to one end of the winding core.

Before a winding core 10 can be brought into contact with the locating claws 30, the support arrangement 12 must be brought into the position shown in FIGS. 1 and 2, in which the two locating claws 30 lie on top. The bellows 78 is depressurized with respect to the ambient air, so that the lever 36 and the clamping claws 32 are in the rest position due to the tensile force of the two springs 44, 46.

  • the rollers 38 come to rest on the first segment 74, which, when the lever 36 moves further, causes the claws 32 to pivot clockwise until they come to rest on the V-shaped wedge 26 of the winding core 10. Since the angle between the second segment 76 of the rolling path of the rolling link 40 and the lever 36 is almost 90 °, the clamping claws 32 are also pressed with a relatively small overpressure in the bellows 78 with a very great force against the web 24, which securely clamps the Winding core 10 on the support assembly 12 results. It should be noted that when the winding core 10 is in place, the pivoting range of the lever 36 is limited by the segment 76 and the safety stop cams do not rest on the mounting claws 30.
