| 摘要 |
An apparatus is disclosed comprising a first color glass feeder having a first valve device, and a second color glass feeder having a second valve device, each connected by communications links to a controller. The controller controls the first valve device and second valve device in order to provide molten glass of a first color and a second color, at a first and a second flow rate, respectively. The controller may be a computer. The controller may include an interactive device into which a first and a second flow rate value can be entered for controlling the first and second flow rates, respectively. The first and second color molten glasses may be incompletely mixed in a channel so that discrete portions of the molten glass of the first color and of the second color can be seen. The controller may also control a robotic mixing device.
