Definitions

  • the present invention relates to protection devices for materials in coil form, in particular for metal sheets in coil form.
  • An example of such protection devices is known from US-5 236 087 .
  • Metal sheets in the form of rolls - or "coils” as they are usually referred to - are normally moved by means of gantry cranes provided with "jaw” or “hook-like” parts which grip a coil, penetrating into the hollow part of the said coil.
  • the jaws may score or in any case damage the part of the metal sheet with which they make contact.
  • the object of the present invention is to provide a protection device for materials in coil form, in particular for metal sheets in coil form, which prevents damage thereto, is simple to manufacture, is easy to fit and has a relatively low cost.
  • the present invention achieves the abovementioned objects by means of a protection device having the characteristic features which are mentioned specifically in the claims which follow.
  • 2 denotes in its entirety a protection device for materials in coil form according to the present invention.
  • the device 2 comprises a first and second plate 4 and 6 which have a respective longitudinal edge zone 8, 10 of smaller thickness ( Figures 2, 4, 5 and 7 ).
  • the plates 4 and 6 each have a respective plurality of retaining and guiding formations 12 which are intended to be slidingly engaged by the corresponding edge zone 10, 8 of the other plate, as can be seen in particular in Figure 7 .
  • Arched transversely folded flanges 16 and 18 are formed at the opposite ends of the first plate 4 and second plate 6, respectively.
  • Respective longitudinal corrugated bands with transverse knurlings Z are formed on the back of the first plate 4 and on the front of the second plate 6.
  • the two plates 4, 6 of a device 2 are coupled together and the device is arranged on one edge of a roil or coil CO radially, in the direction of the thickness, as is shown in Fig. 2 .
  • the two plates 4 and 6 are then slid, towards each other, until their folded flanges 16 and 18 come into contact with the outer curved surface and inner curved surface of the roll or coil CO, respectively, forming a kind of C-shaped clamp which embraces the roll in the direction of its thickness.
  • a second device 2 is arranged and clamped on the opposite edge of the roll or coil CO, in a position longitudinally aligned with that of the first device.
  • This device may be conveniently made of plastic and be able to be adapted to rolls or coils of varying dimensions (thicknesses) and offers an excellent protection against scratching and damage in general.
