Definitions

  • the present invention relates to a method for opening a covering of protective plastics material of a roll of wound metallic material such as, for example, sheet metal strip.
  • Such a covering has a shape complementary to that of the roll so as to be able to enclose it hermetically and, in particular, comprises an outer cylindrical wall and an inner cylindrical wall which are disposed coaxially about the longitudinal axis of the roll, and a first and a second flat wall having the shape of respective annuli which connect the respective facing end edges of the two cylindrical walls.
  • the method of the invention proves to be very rapid and simple in execution and thus permits widespread use of the protective coverings, which has been hitherto restricted by the lack of a convenient method of opening.
  • a roll 10 of wound metallic material such as a sheet metal strip, is surrounded ( Figures 1-3) by a covering 12 of plastics material which insulates it from the outside atmosphere, protecting it from phenomena of corrosion due to the action of atmospheric agents.
  • the covering 12 has a shape complementary to that of the roll 10 and comprises an outer cylindrical wall 14 and an inner cylindrical wall 16 which are disposed coaxially about the longitudinal axis 18 of the roll 10, and also a first and a second flat wall 20 having the shape of respective annuli which connect the respective facing end edges of the cylindrical walls 14 and 16.
  • filiform elements 22, 24 capable of generating heat are disposed.
  • the filiform elements 22, 24 are caused to assume a circumferential arrangement at the centre line plane perpendicular to the axis 18 of the roll 10. If required by particular needs, the filiform elements 22, 24 could however be disposed at any plane perpendicular to the axis 18.
  • Each filiform element 22, 24 comprises a resistor capable of generating heat as a result of the passage of an electrical current.
  • such filiform elements 22, 24 are armoured resistors capable of generating heat over substantially their entire longitudinal extent.
  • the generation of heat thereby is controlled by connecting to an electrical supply the resistors disposed inside them, so as to cause melting of the two circular sections of the covering 12 respectively facing the filiform elements 22, 24.
  • the filiform element 22 disposed on the outside of the outer cylindrical wall 14 is urged to tighten round the latter, while the filiform element 24 disposed on the inside of the inner cylindrical wall 16 is urged to expand against the latter.
  • These stresses may be exerted for example by acting on the free ends 26 of the filiform elements 22, 24.
  • the filiform elements 22, 24 could also be normal electric cables. These, however, once the melting of the facing sections of the covering 12 was completed, would come into contact with the metallic surface of the roll 10, where a dispersion of electrical charges would be created. Therefore, in order to avoid such a phenomenon, it is preferable for the electrical conductors to be conveniently insulated and, in particular, for the filiform elements 22, 24 to be produced in the form of armoured resistors.
