The apparatus for unscrambling and aligning preforms comprises two substantially parallel alignment rollers (121) and rotary pushing means (122) mounted above the said alignment rollers for pushing back incorrectly oriented preforms or nested preforms, and is characterized by at least one of the following characteristics (i) or (ii):
(i) it comprises stopping means (30,31) mounted above the alignment rollers (121) for stopping correctly oriented nested preforms (P2/P3) or an incorrectly oriented preform or incorrectly oriented nested preforms (P4/P5) underneath the rotary pushing means (122) until the rotary pushing means push back the stopped preform(s), said stopping means (30,31) being adapted for letting a correctly oriented preform slide onto the alignment rollers,
(ii) it comprises guiding means (34) for lifting an incorrectly oriented preform or incorrectly oriented nested preforms (P4/P5) into contact with the rotary pushing means (122) said guiding means (34) being adapted for letting a correctly oriented preform slide onto the alignment rollers.
