Abstract

resumo patente de invenção: "método e dispositivo para limpar cabeça de extrusão". a presente invenção refere-se a um método e a um dispositivo para limpar cabeças de extrusão (10) na extrusão de materiais plásticos termoplásticos que são ejetados ou extrusados como pré-forma tubular (12) de um bico de extrusão (14). para remover depósitos e aglutinações interferentes (20) no bico de descarga (14), de acordo com a presente invenção a pré-forma tubular (12) é defletida e perturbada por pouco tempo, em que os depósitos (20) grudados em uma região próxima do bico de descarga (14) são removidos pela pré-forma tubular (12) e transportados para longe. vantajosamente, a pré-forma tubular (12) propriamente dita durante sua deflexão é usada como elemento de limpeza, em que a limpeza acontece automaticamente durante a operação contínua da extrusão contínua sem interromper o processo de produção. 19933175v1
