Abstract

APARELHO E MéTODO PARA FORMAR UMA TIRA DE FILME. Aparelho para a formação de uma tira, formável em uma maior temperatura, em particular, de uma tira que consiste em termoplástico, em percurso contínuo na superfície de um tambor rotativo (1) que deve ser aquecido e/ou resfriado em regiões estacionárias predeterminadas (10, 11). A fim de reduzir as perdas de energia devido à alternação de aquecimento e resfriamento, o tambor de parede fina é montado em um corpo transportador (5) que pode ser aquecido ou resfriado nas respectivas regiões, sendo feita a troca de calor com a superfície do tambor pelo menos nestas regiões.
