<p>Described herein is a method for producing reels (2) of film material having a first thickness (3b) starting from a film material having a second thickness (3a) greater than the first thickness, comprising the steps of : stretching the film material having the second thickness (3a) so as to obtain the film material having the first thickness (3b); forming a reel (2) of material having the first thickness (3b); and executing an operation of cutting on the film material having the first thickness (3b) so as to separate the reel (2) from the remaining part of the film material having the first thickness (3b); the step of forming the reel (2) comprises the steps of winding a first end portion (Pl) of the film material having the first thickness (3b) on a first spindle (21; 26) and displacing, during the winding step, the first spindle (21; 26) into a first position (Q); the step of executing the cutting operation comprises the steps of supporting a second portion (P2) of the film material having the first thickness (3b) on a second spindle (26; 21) set in a second position (R) and cutting a section (S) of the film material having the first thickness (3b) set between the first and second portions (Pl, P2)</p> |
