Abstract

La presente invención se refiere a en un proceso para extruir una tira contínua de un extruído elastomérico producido por una o más extrusoras, haciéndola pasar sobre varios dispositivos transportadores en un tren de equipo, pasar dicho extruído en un dispositivo de balanza o báscula de pesado rodante y contraer el extruído; sin tomar en consideración la secuencia de los pasos anteriores, la mejora que comprende: (a) medir solamente el paso por unidad de longitud de dicho extruído en la balanza de pesado rodante para generar un valor medido. (b) comparar dicho valor medido con un peso de objetivo para obtener una señal de control, y (c) ajustar la velocidad de solamente un dispositivo transportador de velocidad variable entre dichos varios dispositivos transportadores en respuesta a dicha señal de control, de manera de que el peso por unidad de longitud de dicho extruído se controle dentro de límites especificados de peso de + 5 por ciento, sin tomar en consideración ningún cambio en dimensión de dicho extruído y sin variar la operación de dicha extrusora, ni la velocidad de ningún transportador que no sea dicho transportador de velocidad variable; en donde dicho extruído es de material de banda y dicho tren de equipo es una línea de banda.
