Described herein is a shuttle device for producing wrappers of sheet material (F) containing a product (P) with at least one fantail-twisted end obtained by twisting said sheet material (F). The shuttle (10) comprises a first part (112a, 112b) for receiving the product (P) located in the precursor of wrapper and at least one second part (212a, 212b; 312a, 312b) that grips on a respective part of precursor of wrapper (F). The first part (112a, 112b) and the second part (212a, 212b; 312a, 312b) of the shuttle (10) are able to turn with respect to one another about a given axis (X10) so as to produce at least one fantail-twisted end as a result of the twisting action imparted on the precursor of wrapper (F) following upon the relative movement of rotation about the aforesaid given axis (X10).
