Abstract

ESTA BARRA DE METAL DURO O DE CERAMICA MUESTRA AL MENOS UNA PERFORACION INTERIOR (16) EN FORMA DE TORNILLO Y TIENE UNA SUPERFICIE EXTERIOR LISA. LA MASA DEL PRENSADO DE EXTRUSION SE PRENSA A TRAVES DE UNA TOBERA (2) CON UN CANAL (4) LISO. DENTRO DE LA TOBERA (2) SE DISPONE UN DISPOSITIVO DE PASO EN ESPIRAL (8) QUE SOMETE A LA MASA DE PRENSADO DE EXTRUSION A UN MOVIMIENTO DE TORSION, O BIEN ES SOMETIDO A GIRAMIENTO POR LA MASA DE PRENSADO DE EXTRUSION. AL CAUDAL DE LA MASA SE ASOMA MATERIAL EN FORMA DE FIBRAS, P. EJ. FIBRAS ELASTICAS, O BIEN SE INSERTA A PRESION EL MATERIAL EN FORMA DE FIBRAS AL CAUDAL DE LA MASA MEDIANTE LOS CANALES (11, 12, 15). ESTE MATERIAL SIGUE LOS MOVIMIENTOS DE TORSION Y/O DE GIRO Y PRODUCE LA PERFORACION INTERIOR (16) EN FORMA DE TORNILLO. EL UTIL PARA EL PRENSADO DE EXTRUSION TIENE UNA ESPIGA (6) INTERIOR EN LA CUAL SE DISPONE EL DISPOSITIVO DE TORSION (8), CONFORMADO COMO TORNILLO SINFIN, TANTO GIRABLE COMO NO GIRABLE. LA BOQUILLA DE LA TOBERA (3) TAMBIEN PUEDE SER GIRATORIA.
