Abstract: A thread of a fluid material for gasket manufacture is deposited onto a non-planar, non-adhesive support sheet (12) from a nozzle (22) that is displaced above the support along a path corresponding to the outline of the gasket, with subsequent curing of the fluid material. The support sheet is prepared by pressing sheet material into a tridimensional shape whereby its surface contains the non-planar outline of the gasket to be manufactured; the shaped support is positioned with respect to a nozzle carried by a manipulator (20) capable of being controlled to move the nozzle with respect to the support along three independent spatial coordinates; and the nozzle is fed with said fluid material while being displaced along said non-planar outline. Preferably, the support sheet is kept flattened by vacuum against an underlying, matching surface.

Abstract: The process provides for depositing, on a non-adhesive support, a thread of a fluid material for gasket manufacture from a nozzle that is displaced above the support along a path coinciding with the gasket layout, with subsequent curing of the fluid material. According to the invention, a stiff, wirelike reinforcement is placed on the support before deposition, the reinforcement corresponding in shape to the outline of the gasket that is to be manufactured, and having an adhesive surface with respect to the fluid material of the gasket, so that the subsequently deposited thread of fluid material incorporates the reinforcement and becomes bonded to it. The invention also relates to the product obtained by the process.
