Abstract
A continuous glass forming system includes a forming room and at least one forming unit which is advanced successively through a first loading/unloading station, a first heating station, a first forming station, and a first cooling station which are provided within the forming room. The forming unit includes lower and upper mold units, and a sleeve member removably assembled between the lower and upper mold units. The lower and upper mold units have respective first and second forming faces to form a glass blank into a lens. The sleeve member has support faces to support respectively the glass blank and lens. A transfer device moves into or out of the forming room to load or unload the sleeve member into or from the forming unit.
Claims13
A continuous glass forming system, comprising:
- a forming room having a first port;
- a first loading/unloading station disposed within said forming room proximate to said first port;
- at least one first heating station disposed proximate to said first loading/unloading station;
- at least one first forming station disposed proximate to said first heating station;
- a first cooling station disposed proximate to said first forming station;
- and
- a forming device which is advanced successively through said first loading/unloading, first heating, first forming, and first cooling stations, said forming device including at least one forming unit, said forming unit including a lower mold unit, an upper mold unit, and a sleeve member removably assembled between said lower and upper mold units, said sleeve member including a sleeve wall which defines a slot, said sleeve wall having a first shoulder face disposed around said slot and adapted to support a glass blank, and a second shoulder face disposed around said slot and adapted to support a lens formed from the glass blank, said lower and upper mold units respectively having first and second forming faces which are adapted to form the glass blank into the lens within said slot.
A continuous glass forming system, comprising:
- a forming room having a first port;
- a first loading/unloading station disposed within said forming room proximate to said first port;
- at least one first heating station disposed proximate to said first loading/unloading station;
- at least one first forming station disposed proximate to said first heating station;
- a first cooling station disposed proximate to said first forming station;
- and
- a forming device which is advanced successively through said first loading/unloading, first heating, first forming, and first cooling stations, said forming device including at least one forming unit, said forming unit including a lower mold unit, an upper mold unit, and a sleeve member removably assembled between said lower and upper mold units, said lower and upper mold units respectively having first and second forming faces adapted to form a glass blank into a lens, said sleeve member having support faces adapted to support respectively the glass blank and the lens.
A continuous glass forming system, comprising:
- a forming room having a first port;
- a first loading/unloading station disposed within said forming room proximate to said first port;
- at least one first heating station disposed proximate to said first loading/unloading station;
- at least one first forming station disposed proximate to said first heating station;
- a first cooling station disposed proximate to said first forming station;
- and
- a forming device which is advanced successively through said first loading/unloading, first heating, first forming, and first cooling stations, said forming device including at least one forming unit;
- and
- a first transfer device disposed proximate to said first port and being movable into and out of said forming room to load a glass blank into said forming device and to unload from said forming device a lens formed from the glass blank.
