Abstract: An actuator (1) comprising: an actuating element (2); a first mounting (3) and a second mounting (4), configured for allowing the actuating element (2) to be positioned on a reference plane (P); characterized in that: the first mounting (3) is operable to allow the actuating element (2) to move in a direction (X) substantially parallel to the reference plane (P) and to allow a portion of a first end of the actuating element (2) to rotate about a first axis of rotation (T) substantially perpendicular to (X), thereby minimising wear between the actuating element (2) and the first mounting (3) during actuation.

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.

Abstract: An actuator (1), for a printhead, wherein the actuator (1) comprises: an actuating element (2) an obturator assembly (3), engageable with the actuator element (2); wherein the actuating element (2) is operable to assume, depending on a drive signal applied thereto: a rest configuration, in which the obturator assembly (3) is at a first distance (X0) from a reference plane (A); a first deformed configuration, in which the obturator assembly (3) is at a second distance (X1) from the reference plane (A) greater than the first distance (X0), and a second deformed configuration, in which the obturator assembly (3) is in contact with the reference plane (A), wherein: a control module (4) is configured for regulating a drive signal to the actuating element (2) to cause the obturator assembly (3) to move between the rest configuration and the first deformed configuration during a first operating cycle, to reduce the effects of impact on the obturator assembly.

Abstract: An obturator device (1) for a printhead comprising: an obturator assembly (3) having a valve surface (6) movable along at least one direction of displacement (X) between a first position in which the valve surface (6) is at a distance from a reference surface (A) and a second position in which the valve surface (6) is in contact with the reference surface (A); an actuator (2), secured to the obturator assembly (3) and operable to displace the obturator assembly (3) between the first position and second position; characterized in that the obturator assembly (3) comprises: an adjustable coupling (11) configured to allow the valve surface (6) to align its orientation relative to the reference surface (A) thereby ensuring improved engagement between the surfaces.

Abstract: Described is a mould, comprising a pair of mould parts (110, 111), stably couplable to each other during an operating cycle of the mould (100) and between them defining a space (120) for forming an object to be made, and at least one pair of inserts (1, 1?; 2, 2?) made of a material with a high degree of hardness, each of which is removably connected to a respective mould part (110, 111) and mutually engageable in a closed configuration of the mould (100).
