Abstract
A glass forming system includes a first rotating device disposed in a first processing station defining a reception region, a first heating region, a first transfer region and a first cooling region, and a second rotating device disposed in a second processing station defining a second transfer region, a second heating region, a forming region and a second cooling region. The second rotating device holds at least one forming unit and is turnable to move the forming unit between the regions of the second processing station. The first rotating device holds at least one sleeve member which is movable between the first and second rotating devices and mountable on the forming unit. The first rotating device is turnable to move the sleeve member between the regions of the second processing station.
