Abstract
In a rolling machine for continuously manufacturing rolled plates of glass or glass ceramics, in which the two shaping rolls can be changed during operation without interrupting the flow of glass, the two shaping rolls together with at least one replacement roll are disposed in a respective change-over device rotatable around a shaft which is symmetrical relative to all the rolls. To enable both shaping rolls to be rapidly changed during operation, the change-over device for the top shaping roll has a device for rapidly raising and lowering the change-over device and thus raising or lowering the top shaping rolls.
