A transfer unit of hollow glass articles from a first conveyor having a first feeding direction (γ1) and a first feeding speed to a second conveyor having a second feeding direction (γ2) and a second feeding speed, wherein the first feeding direction (γ1) and the second feeding direction (γ2) are incident to one another, preferably orthogonal, and a second feeding speed is lower than the first feeding speed, the unit including: - a first diverter mechanism (3, C3) configured to receive a plurality of hollow glass articles from said first conveyor and to feed said hollow glass articles along a first curvilinear trajectory (γ3) that provides a first deviation of said hollow glass articles, said first diverter mechanism (3, C3) having, during use, a third feeding speed lower than said first feeding speed, - a second diverter mechanism (4, C4) configured to feed said plurality of hollow glass articles along a second curvilinear trajectory (γ4) that provides a second deviation of said hollow glass articles and to feed of said plurality of hollow glass articles to the inlet of said second conveyor, said second diverter mechanism having, during use, a fourth feeding speed higher than said second feeding speed, - a connection mechanism configured to feed a plurality of hollow glass articles from said first diverter mechanism to said second diverter mechanism along a connection trajectory (γ5) that connects said first curvilinear trajectory (γ3) to said second curvilinear trajectory (γ4) thereby enabling, during operation of the unit, a transfer of said plurality of hollow glass articles from said first diverter mechanism to said second diverter mechanism, said connection mechanism having, during use, a fifth feeding speed, wherein furthermore: - the fourth feeding speed is lower than the fifth feeding speed, - the fifth feeding speed is lower or equal to the third feeding speed. - a first diverter mechanism (3, C3) configured to receive a plurality of hollow glass articles from said first conveyor and to feed said hollow glass articles along a first curvilinear trajectory (γ3) that provides a first deviation of said hollow glass articles, said first diverter mechanism (3, C3) having, during use, a third feeding speed lower than said first feeding speed, - a second diverter mechanism (4, C4) configured to feed said plurality of hollow glass articles along a second curvilinear trajectory (γ4) that provides a second deviation of said hollow glass articles and to feed of said plurality of hollow glass articles to the inlet of said second conveyor, said second diverter mechanism having, during use, a fourth feeding speed higher than said second feeding speed, - a connection mechanism configured to feed a plurality of hollow glass articles from said first diverter mechanism to said second diverter mechanism along a connection trajectory (γ5) that connects said first curvilinear trajectory (γ3) to said second curvilinear trajectory (γ4) thereby enabling, during operation of the unit, a transfer of said plurality of hollow glass articles from said first diverter mechanism to said second diverter mechanism, said connection mechanism having, during use, a fifth feeding speed, - the fourth feeding speed is lower than the fifth feeding speed, - the fifth feeding speed is lower or equal to the third feeding speed.
