Abstract

Aparato y método para producir una tabla de yeso que consiste en un aparato para revestir una hoja 14 de cubierta con pasta de yeso de densidad relativamente alta, los aparatos 39, 57, 58 para formar el borde realzado sobre las hojas con pasta de yeso de densidad relativamente alta, y los aparatos 36, 59 para formar un nucleo sobre el revestimiento entre los bordes realzados, consistiendo el nucleo en yeso de densidad relativamente baja. El aparato para revestir la hoja 14 consiste en un rodillo 23 de presion relativamente suave y un rodillo 22 de revestimiento relativamente duro, presionándose normalmente los dos rodillos uno con otro para formar una hendidura de presion entre ellos y una hoja 14 al ser revestida que es pasada a través de la hendidura de presion. El rodillo 23 de presion está debajo de la hoja 14 y el rodillo 22 de revestimiento, y el eje del rodillo 23 de presion está desalineado con el eje de rodillo 22 de revestimiento en direccion del flujo ascendente del movimiento de la hoja 14. El rodillo 23 de presion tiene un área superficial que hace contacto y se mueve en la misma direccion de la hoja 14, y el rodillo 22 de revestimiento tiene una área superficial que hace contacto y se mueve en direccion opuesta de la hoja 14. Se forma una depresion 51 entre el lado superior de la hoja 14 y el rodillo 22 de revestimiento, y se vacía yeso de densidad relativamente alta en la depresion 51. El rodillo rotatorio de revestimiento recoge una cantidad de pasta de la depresion y lo unta sobre la hoja para formar un revestimiento de yeso de alta densidad.
