Abstract

DISPOSITIVO PARA FORRAR UN ANIMA (CONDUCTORES ELECTRICOS) CON UN REVESTIMIENTO PRESENTANDO DOS CAPAS O TIRAS DIFERENTES MATERIALES MONOCROMATICOS. EL MECANISMO PRESENTA DOS CANALES DE ALIMENTACION PARA EL MATERIAL PLASTIFICADO SEPARADO ENTRE SI Y DOS SALIDAS TRANSVERSALES DE MATERIAL PLASTIFICADO ASENTABLES EN EL ANIMA A REVESTIR. LAS SALIDAS TRANSVERSALES SE COMUNICAN CON LOS CANALES DE ALIMENTACION POR DISTRIBUIDORES. PARA NO TENER QUE REALIZAR UNA LIMPIEZA DEL CANAL DEL MECANISMO DE DISTRIBUCION EN UN PROCESO DE CAMBIO DE COLOR O DE MATERIA, EL MECANISMO DE DISTRIBUCION PRESENTA FORMA DE CARTUCHO (8), DISPONE DE UNA CARCASA (1) QUE GIRA ENTRE DOS POSICIONES FINALES Y TIENE CANALES EXTERIORES A LOS CANALES DE ALIMENTACION (2, 3) PARA EL MATERIAL PLASTIFICADO. CADA CANAL DE GUIA (2, 3) DEBE COMUNICARSE CON LAS SALIDAS (15, 20) TRANSVERSALES DE MATERIA PLASTIFICADA PARA ALTERNAR Y ORIENTAR LOS ANGULOS SIMILARES EN EL LADO EXTERIOR DEL CARTUCHO (8).
