A ring machine, for wrapping with stretch film palletized, comprises:
- a ring (5), which is made to rotate by drive means (9) mounted on a frame (2) which rotatably supports the said ring by means of support rollers (3) and containing rollers (4);
- means for supporting the reel (24) of stretch film and means for unwinding from it the film and for statically supplying it to:
- conveying means situated on the said rotating ring (5) and controlled by drive means, for collecting the film supplied from the said static supplying means, so as to accumulate it in the form of annular turns superimposed on each other in an amount greater than that with which the innermost turn of this winding is supplied to the load to be wrapped (C), by supplying means situated on the said rotating ring (5);
- means (27) for temporarily retaining on the load to be wrapped the front end of the film unwound from the said last supplying means.
