1. Interfolding machine having a frame comprising:

  • a feeding section where at least one web of paper is fed at a first speed,a cutting section comprising;

    at least one cutting roller on which at least one blade acts adapted to divide the web of paper into sheets of determined length;

    at least one transfer roller adapted to convey forward at said first speed the sheets cut in turn by the cutting roller;

    an interfolding section at which the sheets of paper coming from the cutting section travel at a second speed less than the first speed, said interfolding section comprising;

    means for partially overlapping the sheets suitable to form an overlapped portion between two consecutive sheets exploiting the difference between the first and the second speed,folding means comprising folding rollers, said folding means being adapted to arrange said partially overlapped sheets in a determined interfolded configuration causing the sheets to form underneath a stack of product;

    a separating section where a stack of interfolded sheets is separated from a next stack and is withdrawn from the area of process through separating means;

    characterised in that said cutting section comprises a portion having a modular structure removable integrally from said frame for being replaced with an equivalent portion that is adapted to work with different cut-off.
