Abstract
The invention concerns a machine for unwinding and rewinding rolls of sheet material. The machine is of the type comprising, on a mounting frame, means for guiding the sheet material unrolled from a reel and a shaft for rewinding it. The shaft is formed from a pin and a counterpin, at least one of which is motor-driven, each carrying a self- expanding spindle that can be inserted into a tubular rewinding core. The machine is characterised by the fact that the pin and the counterpin are mounted at right angles by respective arms that are constrained to slide and rotate along an axis parallel to the preceding one, the rotary constraint being such as to maintain the pin and the counterpin in alignment, the said tubular core, due to the constraint of the said arms and its own weight, resting at the bottom on a sliding support device. <IMAGE>
