Abstract

Un metodo para producir una hoja-correa plastica incluye las etapas de proporcionar primero y segundo rodillos de trabajo de manera que los rodillos de trabajo giran en direcciones opuestas y a diferentes velocidades de superficie lineal. Los rodillos de trabajo estan separados uno con respecto al otro para definir asi una linea de contacto de rodillo de trabajo entre ellos. Esta provisto en rodillo de presion que esta asociado de manera operativa con el primer rodillo de trabajo. El rodillo de presion y el primer rodillo de trabajo que definen una linea de contacto de desaereacion entre ellos. Una hoja solida de material que tiene un espesor es alimentada dentro de la linea de contacto de desaereacion. El material es sujetado con pasadores contra el primer rodillo de trabajo y se mueve con la rotacion del primer rodillo de trabajo hacia la linea de contacto de rodillo de trabajo entre el primero y segundo rodillos de trabajo. El material es molido y estirado de manera simultanea sustancialmente en la linea de contacto durante una sola pasada del material de hoja solida a traves de la linea de contacto a medida que los rodillos giran en direcciones opuestas y a diferentes velocidades de superficie lineal para formar una hoja orientada, molida y estirada. El segundo rodillo de trabajo tiene un perfil concavo para procesar los bordes de la hoja mas que una region central de la hoja. Un rodillo de enfriamiento esta colocado corriente abajo del segundo rodillo de trabajo para enfriar la hoja orientada molida y estirada.
