A seal system includes a male body and a female body that are slidable in relation to one another in an axial direction and between which an interstice is arranged. Plastics in pasty state pass through the interstice to a chamber partially defined by at least one of the aforementioned bodies. An elastic strip is arranged in the interstice to prevent leakage of the plastics.

A method and an apparatus for forming annular doses provides a flow of plasticised material supplied by an extruder which passes through a channel that is first cylindrical and then annular. The material exits from an annular outlet in front of which a cutting element passes that separates an annular dose of material. The dose is deposited on a surface of a capsule having a capacity to adhere to the dose that is greater than the cutting element. The surface and the cutting element are distanced from one another in such a manner that the annular dose remaining adhering to the capsule is detached from the element. Detachment can be promoted by a flow of air.

An apparatus is disclosed for forming annular doses of synthetic plasticised material supplied from an extruder, in which the doses are applied to a surface of a capsule and the seals of the capsules are then compression-formed. The apparatus includes one tubular wall that has a longitudinal axis and is axially movable for closing an annular outlet from which the synthetic plasticised material exits with a component that is normal to the longitudinal axis. The tubular wall has a cutting edge that shears the plasticised material during the closing movement in order to separate the annular dose, formed outside the outlet, from the material that remains inside the outlet.
