Abstract: Apparatus for controlling and adjusting the weight of doses of a loose product in a rotating metering head having telescoping volumetric members distributed therearound. The apparatus includes a rotating control head having a set of sample telescoping volumetric members. A main duct feeds the product to the metering head. A secondary duct is branched off the main duct to feed the control head. A scale is operative to receive individual sample doses as provided by the telescoping members of the control head and to discharge them, after the weighing thereof has been completed, to the metering head. A control assembly adjusts in a concurrent proportional mode the volume of the telescoping members of the metering and control heads according to the weight variations of the weighed product versus the scale reference value.

Abstract: An apparatus for transferring at a predetermined spacing on to a reception conveyor objects fed at an irregular spacing from a continuously moving delivery conveyor. The apparatus consists of a transfer conveyor which moves continuously and at a speed different from that of the delivery conveyor from the delivery conveyor to the reception conveyor, object take-up suckers for transferring the objects from the delivery conveyor and for depositing them at regular distances on the reception conveyor and at least one sensor sensing the position of the objects on the delivery conveyor. The apparatus comprises, moreover, a valve associated with each sucker, at least two control devices adapted to assume a position of engagement with the sucker valves to move them to an activation position and a further control device able to engage with the sucker valves to move them into a deactivation position.
