Abstract
EN DISPOSITIVOS PARA LA ALIMENTACION DE UNIDADES DE EXTRUSION Y DE FUNDICION DE INYECCION CON UN EMBUDO DE RELLENO GIRATORIO Y UN TORNILLO SINFIN DE TRANSPORTE, QUE SE GUIA A LO LARGO DE LA SUPERFICIE INTERIOR DE LA CUBIERTA EXISTE EL PROBLEMA DE QUE EL MATERIAL APLICADO EN BASE AL ROZAMIENTO DE ADHERENCIA NO SUFICIENTE DE LA SUPERFICIE INTERIOR DE RECUBIERTA SE PRODUCE UN RESBALAMIENTO Y NO SE REALIZA EL TRANSPORTE POSTERIOR PREVISTO. PARA CONSEGUIR UNA DISPOSICION AUXILIAR SE PROPONE, QUE LA SUPERFICIE INTERIOR DE CUBIERTA DEL EMBUDO DE RELLENO ESTE PREVISTA EN LA ZONA DE LA MARCHA DEL TORNILLO SINFIN DE TRANSPORTE CON ELEVACIONES Y/O PROFUNDIDADES Y EL TORNILLO SINFIN DE TRANSPORTE TENGA DISPOSICION DE AHORRO PARA EL PASO LIBRE DE LAS ELEVACIONES. ESPECIALMENTE DE FORMA VENTAJOSA POR ESTE MOTIVO SE DISPONEN DE PASADORES AJUSTABLES EN ALTURA.
