Title
(EN) METHOD AND APPARATUS FOR THE MANUFACTURE OF DUCKBILL VALVES
(FR) PROCEDE ET APPAREIL DE FABRICATION DE VALVES A BEC DE CANARD
Abstract
(EN)
A method and apparatus for manufacture of duckbill valves (1) in which the opposed lips of the valve (1) are split by applying a high fluid pressure inside the valve (1). This pressure causes the valve to balloon and burst. Preferably, the valve (1) is supported over all of its outer surface except the end (6) to be split by a die (5, 10). The system is particularly suited to duckbill valves made of thermoplastic elastomer.
(FR)
Procédé et appareil de fabrication de valves (1) à bec de canard dans lesquelles les lèvres opposées de la valve (1) sont séparées par l'application d'une forte pression de fluide à l'intérieur de la valve (1). Cette pression fait gonfler et éclater la valve. De préférence, ladite valve (1) est supportée sur toute sa surface extérieure à l'exception de l'extrémité (6) qui doit être divisée par un dé (5, 10). Ce système est tout particulièrement adapté à des valves à bec de canard réalisées en élastomère thermoplastique.
