Abstract
Plant for manufacturing latex foam layer of unlimited length and having lower and upper recesses. A plurality of laying planes provided with lower protuberances proceeds between an injection station and a layer removing station. Foam provided with lower recesses is directed towards a vulcanizer between the injecting station and the removing station. A plurality of upper plates, each provided with protuberances, is lowered, one by one, on the foam layer to impress upper recesses before the foam layer enters the vulcanizer. The plates, placed on the foam layer, have their ends shaped to avoid any penetration of steam condensation drops. Upper plates release their weight to fixed supports of the planes to which they are bound until they leave the vulcanizer. The return of the plates from the extraction station towards the new cycle of moulding is independent of the operating system of the planes.
