Abstract
Procedimiento y dispositivo de extrusión hidrostática continuade un primer objeto denominado esbozode longitud indefinida en un segundo objetode longitud igualmente indefinidapero de sección diferenteel procedimiento caracterizado porque el esbozoacompañado de una cantidad sustancial de un fluido viscosose introduce en una entallarealizada en un motor de accionamiento y en la que el esbozo delimita dos zonas concéntricas separadasla primeradel lado externofrente a un estator que forma tapa aplicado sobre el rotorque engendra una presión progresivamente creciente del punto de entradaa la presión ambiente hasta la cámara donde reina la presión de extrusión yde un modo generalmás elevada que la que reina en la segunda zonadel lado internoen el fondo de la entallaejerciendo esta diferencia de presión sobre el esbozo una fuerza que tiende a aplicarlo en la entalla y que engendra una adherencia suficiente para que el movimiento del rotor arrastre el esbozo sin deslizamientode la parte anteriora la presión ambientehasta la posterior a la entrada de una cámara a elevada presión de donde se escapa por extrusión a través de al menos un orificio de extrusionadora.
