Abstract: The apparatus for melting off a glass top part from a hollow glass blank has individual burner sections (3) each containing at least one burner nozzle. The individual burner sections (3) are held in a cutting plane and movably connected with each other. A control device (4a, 4b, 5) controls the respective positions of the burner sections (3) so that they fit any arbitrary outer contour of the hollow glass blank (1). The control device (4a, 4b, 5) holds and maintains the burner sections (3) at a constant distance from the exterior surface of the hollow glass blank (1). The burner device with the burner sections (3) is mounted on two half frames pivotally connected with each other for better access to the glass object (1). This apparatus separates the glass top part from oval or triangular glass objects, which should be cut at an inclined orientation, in a single step.

Abstract: A machine for processing hollow glass objects (8) is described. The machine includes a sequence of like processing units (1) to (15) and (A, B) on which a small number of processing steps can be carried out on the workpiece (8). The workpieces (8) are brought to the processing unit on a clock-driven loading belt (4) and taken therefrom. A workpiece, which is being processed in a unit, is held during the entire sequence by one and the same workpiece holder. Each processing unit includes two separate handling units with which two workpieces run through the workstations time displaced. The machine arrangement permits processing units to be taken out or switched into the line without a production standstill.

Abstract: The apparatus for melting off a glass top part from a hollow glass blank has individual burner sections (3) each containing at least one burner nozzle. The individual burner sections (3) are held in a cutting plane and movably connected with each other. A control device (4a,4b,5) controls the respective positions of the burner sections (3) so that they fit any arbitrary circumference of the hollow glass blank (1). The control device (4a,4b,5) holds and maintains the burner sections (3) at a constant distance from the exterior surface of the hollow glass blank (1). This apparatus separates the glass top part from oval or triangular glass blanks, or also from glass objects with a circular cross-section, but which should be cut at an inclined orientation, in a single step.
