Abstract
A change system for changing an orifice plate that is registered with an orifice ring is provided. The orifice plate change system includes a guide arrangement, a plurality of orifice plates, and an actuator. The guide arrangement has a charging plate region and an operating plate region. Each orifice plate is configured to be slidably carried by the guide arrangement between the charging plate region and the operating plate region in which the orifice thereof is registered with the orifice ring orifice. A first orifice plate has a first orifice and a second orifice plate has a second orifice that is different than the first orifice such that a stream of molten glass that passes through the second is different than a stream of molten glass passing through the first orifice. The actuator translates the orifice plates from the charging plate region to the operating plate region.
