A transfer device, particularly for flexible laminar products, includes a belt (2) of preset length, the ends (3, 4) whereof are anchored and partially wound around two oppositely arranged main rollers (5, 6); a motor (9) which acts on the main rollers (5, 6) to wind and respectively unwind, with controlled torques, the ends of the belt, keeping it constantly stretched, as well as a ramp (12) for depositing one or more products (P) onto the surface of the belt (7) which is directed toward the takeup roller, so as to convey the products toward this roller and retain them between this roller and the wound belt portion. The main rollers (5, 6) have identical tangential peripheral speeds with continuously opposite rotation directions. The motor (9) includes, for each of the main rollers (5, 6), a servomotor with torque control which is controlled by an intelligent controller (11) which is programmed so that at all times the torque which acts on the takeup roller is greater than the torque which acts on the unwinding roller. |
