A method for producing packages of folded or interfolded laminar products made of paper, in particular packages of napkins, tissues, towels, or similar products, said method comprising the steps of:

• folding or interfolding, by a folding or interfolding group, equipped with a first and a second folding or interfolding roll a plurality of sheets to form a stack of folded or interfolded sheets according to a predetermined folding or interfolding configuration arranged to grow in height along a vertical forming direction;
• separating a completed stack of folded or interfolded sheets once that a predetermined height of said stack being formed is reached, from a following stack being formed positioned upstream of said completed stack along said vertical forming direction, said separating step being carried out by a first and a second separator member arranged to enter into said stack being formed from opposite sides to separate said completed stack from said following stack being formed, said first and second separator members being arranged to support together said stack being formed;
• transferring by a transfer group said completed stack on a discharge device configured to discharge said completed stack from said machine;
• discharging by a discharge device said completed stack from said machine;
• and
• moving by a displacement device said discharge device along a displacement direction towards/from said transfer group.
