A machine for packaging piles of paper products, such as serviettes, handkerchiefs and the like, comprising:

• a feed assembly for feeding a sheet of packaging material, comprising means designed to hold a sheet of packaging material in a substantially vertical plane;
• a station for feeding products to be packaged, comprising a pusher designed to push the products to be packaged in a longitudinal direction orthogonal to the aforesaid sheet of packaging material;
• a drawer device comprising a bottom plate and a top plate, in which the top plate is cylindrically mobile with respect to the bottom plate by a given dimension;
• a first control device designed to control displacement of the drawer device in a longitudinal direction between a receiving position and a position of release of the products,
• a second control device, independent of the aforesaid first control device, for controlling displacement of the top plate in a vertical direction with respect to the bottom plate by the aforesaid given dimension, said control device being designed to vary the aforesaid given dimension with the machine moving, and wherein
• a control unit of the machine controls said variation in the given dimension as a function of a signal indicating a torque of a motor which controls compression of the pile of products to be packaged.
