摘要

Process for portioning a continuously flowing low viscous glass strand (1) into uniform large glass gobs (2) comprises using a rotating tool (3) with blades (4) which shear gobs from the glass strand. Preferably the viscosity of the glass strand is 1-1,000 dPa.s. The tool is a cutter with at least one cutting edge (5) in the region of one blade. The surface of the rotating tool and the tool base body is cooled using water. The sheared glass bog is placed in a cooling bath.
