Abstract: Apparatus to neutralize static electricity present on the surface of containers (100; 10?) and/or of nests (200; 300) comprising a plurality of seatings (212; 312) according to a positioning matrix (M1) and able to receive, resting on them, an ordered group of said containers (100; 100), wherein the apparatus comprises an extraction member (15) configured to engage at least one part of said ordered group of containers (100; 100?), in order to perform at least one relative lifting movement with respect to the nest (200; 300) so as to at least partly extract the containers (100; 100?) engaged from the respective seatings (212; 312), and at least one ionizing device (19) configured to be relatively mobile with respect to the extracted containers and/or with respect to the nest (200; 300), while said group of containers (100; 100?) extracted is in said raised condition, along a path that develops in the proximity of the containers (100; 100?) extracted and/or in the proximity of said nest (200; 300), so as to ion

Abstract: A weighing device to weigh at least one container suitable to contain one or more substances, including weighing means and a body connected to the weighing means and in which a compartment is defined, configured to temporarily house the container and provided with an aperture defining a passage gap for the introduction of the container inside the compartment along an axis of introduction, in which the body also includes a plurality of holding levers to hold the container inside the compartment.

Abstract: The ultrasound welding device, for welding flexible packages is disclosed. The device includes: a power generator to generate a sinusoidal electric signal at a predetermined frequency; a transducer operatively associated with the power generator to transform the electric signal generated by the latter into mechanical vibrations having the same frequency as the electric signal; a sonotrode associated with the transducer and structured to amplify and transmit the mechanical vibrations generated by the transducer to a welding surface defined on the same; and a contrast element provided with a contrast surface arranged to engage the welding surface of the sonotrode during the welding operations. The transducer and sonotrode are engaged so as to amplify and transmit the vibrations generated by the transducer to the welding surface of the sonotrode without an amplifier or similar device.
