Definitions

  • the invention relates to a hub-shaped anti-deformation device which can be inserted into the cylindrical cavity of a large winding, such as an aluminum or steel band winding, in the form of a circular blank which has a cylindrical opening in its center (US Pat. No. 4,015,711).
  • the invention relates to large rolls of aluminum or steel strip, which have to be transported as semi-finished products for further processing from the rolling mill to a factory in which finished products, for example beer cans, are produced from the strip. These large packages are transported upright on pallets. It can happen that the coils, which have a high weight, shift and collide against one another when the transport vehicle accelerates strongly or negatively. The coils can be deformed in such a way that they are no longer processed in the factory, i. H. can be processed.
  • a deformation protection is known, which is essentially pot-shaped and is provided in the bottom with a circular opening. It is mainly used for wrapping paper tape or plastic films. Notes in the publication indicate that this known deformation protection should be made in one piece from plastic. This known deformation protection is not stable enough to be used as deformation protection in large windings made of aluminum or steel strips.
  • a deformation protection which also has a cup-shaped shape, but the bottom of which is approximately funnel-shaped.
  • This known deformation protection is to be inserted into the ends of a cylindrical winding core on which paper tapes are wound. It is said to be made of sheet metal. If such a known deformation protection should be designed so that it would be useful for large windings made of aluminum or steel strips, then much stronger metal sheets would have to be used, which can no longer be deformed so easily.
  • This well-known anti-deformation device is too expensive - if usable at all - for use with large coils.
  • the invention is therefore based on the object of creating a deformation lock which, even with strong radial force acting on the winding, maintains such a shape that the winding can still be processed and which nevertheless remains in the cylindrical cavity of the winding.
  • the new deformation lock should be easier and cheaper to manufacture than the known deformation locks.
  • the round plate has such a U-shaped cross section, in which the horizontal leg is concavely curved outwards and the inner leg is slightly inclined towards the inside in relation to the axis of symmetry.
  • Fig. 1 shows a large roll 1 ready for transport, which is placed upright on the pallet 2. At least in one end, namely the upper one At the end of the cylindrical cavity 3 of the large roll 1, the deformation lock 4 is inserted, which is intended to prevent forces which act on the large roll 1 in the direction of the arrows from deforming it in such a way that it can no longer be processed.
  • Fig. 2 shows the cross section of the new deformation protection 4. It consists of a ring with a U-shaped cross section and the cylindrical opening 5.
  • the U-shaped cross section consists of the slightly curved horizontal leg 6, the inner leg 7 and the outer leg 8
  • the inner leg 7 is inclined to the longitudinal axis of the anti-deformation device and is provided with the step 9 at its free end.
  • webs 10 are fastened, preferably three pieces, each offset by 120 degrees.
  • the deformation protection 4 shown in FIG. 2 is inserted into the cylindrical cavity 3 of the large winding 1 and is subjected to radially acting forces, then the resulting energy is converted into deformation energy in the horizontal leg 6, which leads to the fact that it moves out of the curved shape turns into an S-shaped shape. Even if the radial forces are so strong that the outer leg 8 breaks away, the rest of the deformation protection is still able to maintain the cylindrical cavity 3 in such a way that the large winding 1 can be processed.
  • Fig. 3 illustrates the function of stage 9. It facilitates the stacking of a large number of deformation locks.
  • the new deformation lock 4 can be produced more cheaply and with less weight if it is pressed in one piece from a non-rising mixture of lignocellulosic particles and a thermosetting binder.
  • the non-climbing mixture is, for example, lignocellulosic fibrous materials, such as shredded and dried wood chips, bagasse fibers and the like. ⁇ ., which are mixed with a thermosetting synthetic resin, such as a melamine, urea formaldehyde or phenol formaldehyde resin.
  • a thermosetting synthetic resin such as a melamine, urea formaldehyde or phenol formaldehyde resin.
  • fibers of other materials such as glass fibers, rock wool or asbestos fibers, alone or several of them mixed with one another, to which appropriate, preferably organic binders have been added can also be used.
