Apparatus and method for stacking a separator strip and sheets of foil, preferably for an electrochemical cell intended for producing batteries

A stacking apparatus for stacking a separator strip and sheets of foil, said apparatus comprising:

• a stacking unit comprising:
• A stacking surface, configured to receive said separator strip and said sheets of foil,
• a feeding unit configured to feed said separator strip along a feed path, wherein:
• said feeding unit comprises an outgoing orientation control device placed directly upstream of said stacking unit,
• said outgoing orientation control device is designed to define an outgoing reference direction of said separator strip,
• a handling unit comprising a first and/or a second handling device configured to respectively move said outgoing orientation control device and/or said stacking surface so as to maintain a first distance between said outgoing orientation control device and said stacking surface, measured according to said outgoing reference direction, comprised between 0 and 30 mm, more preferably between 0 and 15 mm, even more preferably substantially equal to 0 mm.
