Abstract
A gob trough for guiding a gob of molten glass is provided. The trough may be formed from trough segments that have a stepped configuration that reduces the amount of contact time between the gob and the trough. The trough may include surface formations that additionally reduce the contact time between the gob and the trough.
Claims27
A trough for guiding glass gobs comprising:
- an upward facing first trough segment defining an internal gob guide surface, the first trough segment having a first end and a second end;
- an upward facing second trough segment defining an internal gob guide surface, the second trough segment having a first end and a second end, the first trough segment being connected to the second trough segment with the second end of the first trough adjacent the first end of the second trough;
- and
- the internal gob guide surface of the first trough at the second end of the first trough segment being vertically offset above the internal gob guide surface of the second trough at the first end of the second trough segment forming a vertical step when transitioning from the internal gob guide surface of the first trough to the internal gob guide surface of the second trough;
- wherein the internal gob guide surface of at least one of the first and second trough segment includes a plurality of surface formations formed between the first and second ends of the corresponding trough segment, the plurality of surface formations includes:
- a first row of surface formations that are spaced apart along a first axis extending between the first and second ends, the surface formations of the first row of surface formations having a first dimension parallel to the first axis;
- a second row of surface formations that are spaced apart along a second axis parallel to and offset from the first axis, the surface formations of the second row of surface formations having a second dimension parallel to the second axis, the second dimension being less than the first dimension.

A trough comprising:
- an upward facing trough segment defining an internal gob guide surface, the trough segment having a first end and a second end;
- and
- a plurality of surface formations located along the internal gob guide surface and located axially between the first end and second end;
- wherein the plurality of surface formations includes:
- a first row of surface formations that are spaced apart along a first axis, the first row of surface formations extending a first length between a first surface formation in the first row and a last surface formation in the first row, the surface formations of the first row of surface formations having a first dimension parallel to the first axis;
- and
- a second row of surface formations that are spaced apart along a second axis, the second row of surface formations extending a second length between a first surface formation in the second row and a last surface formation in the second row, the second length being less than the first length, the surface formations of the second row of surface formations having a second dimension parallel to the second axis, the second dimension being less than the first dimension.
