Abstract: Machine for applying sealing material to a metal element comprises at least one electromagnetic mandrel provided with a main body to house at least one electromagnet and a support to hold the metal element in position on a work surface following the excitation of the electromagnet; the main body is connected to drive means configured to make the support rotate on the work surface; the delivery device of the sealing material is positioned at least in proximity to the periphery of the metal element and is able to deliver sealing material when the metal element is held in position and made to rotate on the work surface by means of the support of the electromagnetic mandrel.

Abstract: Dispenser (1) for adhesive Newtonian fluid, comprising: a syringe (5) containing the adhesive fluid; a plunger (23) for pushing the adhesive fluid out of the outlet spout of the syringe (5); an inlet (27) for a propellant gas; means (28) for mixing the adhesive fluid coming out from the syringe (5) and the propellant gas coming from said inlet (27) in order to obtain a mixture deliverable by atomization on a surface, said means (28) for mixing being shaped in such a way that the mixing of the adhesive fluid and the propellant gas takes place in proximity to an open end (14a) of a cannula or catheter (14) of the dispenser (1).
