Abstract: A self-centring device for supporting and guiding bars to be fed to a machine tool, including:
a guide body having a through opening, supported rotatably and rotating in a controlled manner around an axis perpendicular to an advancement direction of the bars to be guided, so as to vary the angular orientation thereof around the axis; the guide body is configured to receive and maintain in position the rotating and advancing bars,
a return member configured to oppose a suitable preselectable resistance to the rotation of the guide body around the axis so as to maintain a firm coupling and contact of the guide body with the advancing bar,
a manual selector member configured to adjust a position and control the angular movement of the guide body. The manual selector member includes a screw arrangement cooperating with an oscillation limiting element to set an angular rest position of the guide body in function of the geometry of the bar to be received and guided to said machine tool.-

Abstract: A propulsion device for a two-wheeled vehicle includes
a mechanism for providing traction to a rear wheel for manual advancement of the vehicle
and a first epicyclic gear reducer coupled with the mechanism and drivable by a first control device configured for varying the geometric configuration of the first epicyclic gear reducer and thus the gear ratio.
A motor for assisting pedalling is interposed between the mechanism for the bottom bracket and the rear wheel and is coupled with
a second epicyclic gear reducer, drivable by a second control device configured for varying the geometric configuration of the second epicyclic gear reducer and thus the corresponding gear ratio. The second epicyclic gear reducer is coupled and directly in contact with the rear wheel in order to transmit the movement from the propulsion device thereto.-

Abstract: A device and method for recovering and unloading bar crop ends is suitable for use with a loading apparatus for supplying bars to a machine tool. The devices includes a grasping element suitable for engaging a bar-pushing unit of the loading apparatus and a bar crop-end to be taken and unloaded. A slide element receives and conveys the bar crop ends to a collecting zone. A supporting and transferring unit transfers the grasping element from an upper position, in which it is axially aligned on the advancement trajectory of the bar-pushing unit, to a lower position in which it is near the slide element. The device further includes an ejecting unit that is drivable for penetrating the grasping element in the lower position to eject the crop end and sending the crop end, by the slide element, to the collecting zone.A method is also disclosed for recovering and unloading bar crop ends from a machine tool.
