Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA LA REALIZACION POR EXTRUSION DE ELEMENTOS LONGILINEOS DE ESTRUCTURA LAGUNAR Y ELEMENTOS ASI OBTENIDOS. EN DICHO PROCEDIMIENTO UN MATERIAL SINTETICO TERMOPLASTICO ES INTRODUCIDO EN ESTADO VISCOSO O PLASTICO EN UNA CABEZA DE EXTRUSION PROVISTA DE UNA RANURA DE EXTRUSION ASOCIADA A UNOS MEDIOS DE OBTURACION DESPLAZABLES, APTOS PARA INTERRUMPIR LOCALMENTE Y DE FORMA INTERMITENTE EL FLUJO DE MATERIAL VISCOSO, MANDANDO ASI LOS MEDIOS DE OBTURACION DE MANERA QUE CREEN EN CONTINUO, EN EL SENTIDO LONGITUDINAL DE DICHO ELEMENTO, UNA PARTE SENSIBLEMENTE MACIZA Y UNA PARTE SENSIBLEMENTE LAGUNAR, AMBAS CONTIGUAS. LA INVENCION SE APLICA A LA EXTRUSION DE VAINAS DE PROTECCION PARA ARBUSTOS Y PLANTAS.
