The present invention relates to a method of manufacturing bags including complementary closure strips, the method comprising the steps consisting in: separately feeding a film and closure strips having sequential thin zones at the same pitch as the bags; and fixing the strips to the film; the method further comprising the steps consisting in: detecting loss of synchronization between the closure strips and means acting in the assembly station; and in the event of loss of synchronization being detected, modifying the size of the sequential thin zones provided in the strips so as to reestablish synchronization. The present invention also relates to a machine for implementing the method, and to the bags obtained thereby.
