Abstract

Patente de Invenção: <D>"PROCESSO PARA A ALIMENTAçãO DE GRANULADO DE MATERIAL SINTéTICO NA ABERTURA DE ENTRADA DE UM EXTRUSOR DE MATERIAL SINTéTICO"<D>. A invenção refere-se a um processo para a alimentação de granulado de material sintético na abertura de entrada de um extrusor de material sintético, com um reservatório, e com um reservatório intermediário apoiado sobre um dispositivo de pesagem, sendo que no cabo do processo a quantidade de material determinada de acordo com o peso, processada para a respectiva ordem, é determinada por meio de rotações do fuso do extrusor. Para indicar um processo, no qual os tempos alternados de receita e de ordem se encurtam consideravelmente, e o granulado de material sintético seja economizado, está previsto que o reservatório intermediário seja enchido por meio da abertura da saída do reservatório, com uma quantidade determinada de granulado de material sintético, determinada de acordo com o peso, e o reservatório seja enchido depois do novo fechamento de sua saída com sua quantidade de enchimento constante, se a soma do peso dos enchimentos dos dois recipientes corresponder à quantidade residual que permanece, determinada de acordo com o peso a ser processado pelo extrusor, pelo fato de que o transporte de material sintético para o reservatório é interrompido e esse reservatório é aberto uma vez ou várias vezes, até que a quantidade armazenada por ele tenha entrado no reservatório intermediário.
