Abstract

Apparatus and method for forming seals, such as composite seals in rubber/metal or other materials, includes supplying a raw elastomeric mixture in the form of a suitably shaped extrusion, and optionally a metal or other material insert, to respective loading and a possibly metal or other material insert are supplied to respective loading stations of a transfer machine; the machine is provided with a plurality of carriers each composed of at least two pivoted leaves joined in book-like fashion and each carrying a respective mould half, respective spring presses movable on the machine together with the said carriers, and cam means for holding the said carriers open at the loading stations; after cleaning of the mould halves and spraying of the upper mould half with a release agent a said insert is deposited between the mould halves by means of manipulators able to self-center themselves with respect to each carrier and then a blank of raw mixture obtained by slicing the extrusion is deposited between the mould halves; finally each carrier is closed in such a way as to bring the mould halves together, disposed clamped under the corresponding spring press and fed into a polymerization tunnel.
