Patent ID: 8739731

Claim:
A delivery assembly for depositing a gasket made of polymeric material within a seat having a predefined shape provided within a product, the delivery assembly comprising: at least one working head provided with a nozzle for dispensing in the seat of the product polymeric material, that is substantially in the liquid state and is suitable to form the gasket, said nozzle being provided with a support thereof, wherein the polymeric material is such that an increase in volume is associated therewith at the phase transition from liquid to solid so as to provide the gasket expanded, due to the increase in volume, defining by interference a stable coupling with the seat; an automatic and reprogrammable movement apparatus for said at least one working head, which is adapted to define for said nozzle a trajectory that replicates a profile of the seat; and at least two joints that connect said automatic and reprogrammable movement apparatus to said support of said nozzle, wherein said support is substantially constituted by a first plate, which supports said at least one working head and said nozzle, and by a second plate jointly connected to said movement apparatus, said first plate being connected to said second plate by means of said at least two joints that are provided so as to act elastically between said first and second plates, respectively along two mutually perpendicular directions, to allow relative movements of said nozzle with respect to said automatic and reprogrammable movement apparatus along said two mutually perpendicular directions.
