Abstract: The present invention relates to a filling device for heterogeneous products or products which have solid or semi-solid suspended elements with variable dimensions and compactness. The valve of the invention can be used in net weight filling machines. In particular, the invention relates to a filling device (1) for filling machines, comprising a hollow body (2) in which a shutter member (3) is movably fitted and acts in cooperation with a dispensing member (4), which is coaxial to said shutter member (3), to close or open a dispensing opening (5) for a product (P) to be dispensed into a container (C), characterized in that said dispensing member (4) comprises a rotatable shaft (10) comprising a screw portion (14) adapted to impart a dispensing pressure and a mixing to the product (P).

Abstract: A labelling machine (1) for labelling containers moving on a transport system (2), includes a labelling unit (8) having a supplying roll (19) of a pre-printed label web and a cutting drum (20) providing for both cutting a label from the label web and applying it onto a container. The cutting drum (20) is located at the release point of a label to the container to be labeled.

Abstract: A pressure adjustment device applicable in particular, but not exclusively, to stretch blow molding machines. More particularly, the invention relates to a pressure adjustment device for stretch blow molding machines of containers made of plastic material. The device includes an opening for dispensing a blowing fluid, a hollow body having a first inlet opening for a high pressure fluid and a second inlet opening for a piloting fluid. A shutter is slidably arranged within the hollow body, the shutter being held in a closed position by elastic means, wherein the adjustable opening of the shutter occurs, in contrast with the elastic means, by introducing—through said second inlet opening—the piloting fluid into a piloting chamber arranged between the hollow body the shutter, and wherein the piloting fluid has a controlled and adjustable pressure.

Abstract: The invention is generally applicable to labeling apparatus, and relates to a device (10) for rotating Container plates in a labeling apparatus; such device (10) being engaged by at least two wheels (1) with a cam (5) for guiding and rotating it, so that the plate connected therewith is also rotated; each wheel (1) consisting of at least one rigid element (2) and at least one elastic disk (3) coupled thereto, having a greater outside diameter, so that the cam (5) is first contacted by said elastic disk (3). As the load between the elastic disk (3) and the cam (5) is increased, and such disk (3) is elastically deformed, the cam (5) is contacted by the rigid element (2).

Abstract: The present invention relates to a hydraulic pressurization system, in particular for application to pressurization devices operating in accordance with the high hydrostatic pressure principle. In particular, the present invention provides a pressurization system for modifying the pressure in a pressurization device. The system comprising a first hydraulic circuit in which one or more primary pressure accumulators are connected to the pressurization device in controlled manner in order to permit a substantially incompressible fluid to be admitted to and removed from the pressurization device at a first pressure, the primary pressure accumulators being precompressed-gas pressure accumulators.
