Definitions

  • the present invention relates to a device allowing the manipulation by unwinding of various products presented in rolls and more particularly films of stretchable plastics intended for the packaging of the most diverse products.
  • rolls are very generally in the form of a cardboard sleeve on which is wound a very long length of a thin film of variable width, but generally of the order of 0.25 microns.
  • the operator fixes the free end of the film at a point on the product, and must then wrap this film all around the product, unrolling it as the roll, until the packaging is completed, as a result of which the product is enclosed in a volume of film adhering to itself.
  • the invention eliminates these drawbacks, thanks to specially designed end caps which can easily be fitted inside the cardboard sleeve, and then allow the roller to be manipulated around the product by unrolling and stretching the film with ease and precision.
  • the end piece according to the invention preferably comes from molding in a single piece of material, plastic, and has an internal portion and an external portion, the first intended to be introduced elastically inside the cardboard sleeve and to it. serve as a pivot, the other intended to be taken in each hand by the operator.
  • the internal portion is in the form of a “tulip”, and is in the form of two truncated cones joined by their large base, their junction having a diameter slightly greater than that of the sleeve, and hollowed out along several generatrices so as to be able be compressed elastically inward.
  • the external portion consists of a circular crown delimiting the most tapered of said truncated cones and having a diameter slightly greater than that of the sleeve, this crown being connected to a handling disc by a hollow zone flared outwards.
  • the device according to the invention consists of a so-called internal portion 1, having the shape of the two truncated cones 1 and 2 joined by their large bases along a line 3, and cut by slots 4. At rest, the diameter D of the device is slightly greater than the internal diameter D 2 of the sleeve 5 on which the plastic film 6 is wound.
  • the small base of the most tapered truncated cone is closed by a circular crown 7 whose diameter is greater than the external diameter D 3 of the sleeve 5.
  • a handling disc 8 is connected to the crown 7 by a flare 9.
  • the tulip formed by the petals defined in the trunks of cones 1 and 2 by the slots 4 can compress slightly inwards when the device is pressed into the sleeve 5. Its introduction is further facilitated by the fact that the small base of the cone 2 has a diameter less than D ,.
  • the sleeve slides easily along line 3, which allows, using a device at each end of the sleeve, to rotate the sleeve around the axis XX 'in now by the 8-8 'discs which remain fixed in rotation.
  • Said discs 8-8 ' allowing, moreover, a good grip, the operator can easily handle the roll of film, unrolling it by simple displacement around the product to be packaged, the roller rotating itself around the axis XX' .
  • a condition for the proper functioning of this device is the sufficient degree of penetration into the sleeve to ensure sufficient support around the line 3.
  • a depression of the line 3 therefore a distance from line 3 to crown 7 of about 5 cm is satisfactory.
