Abstract: Device for controlling and regulating the spacing of parcels, packages or similar objects and, more particularly, of postal parcels, mounted at the outlet of a separation apparatus that includes a truncated cone-shaped rotating drum with its axis inclined towards the horizontal and having internal helical fins designed to deliver the packages one by one to the outlet of the drum. The device further includes a conveyor belt driven at constant speed and onto which the packages are tipped at the outlet of the drum, a barrier of detection cells, the beam of which extends in perpendicular to the line of travel of the conveyor in order to identify the moment of each package's passage into this beam and to measure, between two successive interruptions of the cells, the relative spacing of two consecutive packages intersecting, each in turn, the beam of the cells.

Abstract: A rotary device performing the task of changing the direction of advancement of a plastics card or metal plate, suitable for being inserted in a punching machine, constituted by a bearing structure, a linear conveyor for the plastics card or metal plate and a drive motor, in which the bearing structure comprises a lower, fixed framework, inside which the drive motor is housed, above which a upper, rotary framework is rotatably supported, on which the linear conveyor is positioned. A first positive transmission connects the drive motor with the upper, rotary framework of the structure, causing the upper, rotary framework to rotate by a predetermined angualr rotation, and a second positive transmission connects the drive motor with the linear conveyor which conveys the plastics card or metal plate. Between the two positive transmissions and the drive motor two free-wheel mechanisms are interposed, which cause the two positive transmissions to be selectively actuated.
