  • Known unwinding machines generally allow the unwinding of coils of large width, mounted by means of their mandrel on the centering heads of spool-holder arms pivotally mounted on rotary supports and lockable in the service position on said supports. rotary, and are therefore almost not suitable for unwinding narrow coils and, in particular, not for unwinding at least two narrow coils, simultaneously.
  • Such an embodiment allows the simultaneous unwinding of two strips from two separate reels and the lateral retraction of the intermediate support arm, in its rest position.
  • the intermediate spool holder arm is rigid and therefore does not allow its centering heads to move away from the central shaft, so that the spools cannot be gripped on the ground .
  • the coils must be brought with their mandrel in front of the centering heads of the lateral reel arms and of the arm intermediate by means of a lifting handling device to be able to be gripped by introducing said heads into the mandrels.

  • This means 13 allows, in its operating position, an application of a strip of large width on a single coil for the connection operation.
  • the means 26 and 31, respectively for pivoting actuation of each cylinder 22 individually and for pivoting actuation of the single cylinder 27, are advantageously in the form of jacks, the piston rod of which is articulated on the corresponding lever 23 or 28, eccentrically with respect to the corresponding pivoting guide shaft 25 or 29, and the yoke of which is mounted on a cross member 15 "of the rotary support 15.
