Method and apparatus (100) for applying a cap (230, 430, 440, 450, 460) to a container (200), comprising arranging a first cap (230, 430, 440, 450) in relation to the neck portion (220) of a first container (200), such that a threaded portion (240) of the first cap (230, 430, 440, 450) faces a complementary threaded neck portion (228) of the first container (200) and such that a symmetry axis of the first cap (230, 430, 440, 450) and a symmetry axis of the neck portion (220) of the first container (200) are aligned, rotating the first cap (230, 430, 440, 450) around its symmetry axis to a pre-recorded initial angular position, applying the first cap (230, 430, 440, 450) to the neck portion (2250) by moving the cap (230, 430, 440, 450) towards the threaded neck portion (228) or vice versa along their symmetry axes and by rotating the first cap (230, 430, 440, 450) in a direction of engagement with the threaded neck part (228) and recording a path length of the first cap (230, 430, 440, 450) in relation to its initial angular position after which it has completely engaged the complementary threaded neck portion (228) and reached a bottom part of the neck portion (220). If the recorded path length for the first cap (230, 430, 440, 450) deviates from a predefined value the initial angular position of a second cap is adjusted to a new initial angular position. |
