Abstract
On shearing a melted glass stream flowing along a first direction at a first speed into a melted glass lump flowing along the first direction at a second speed faster than the first speed by a cutter section, the cutter section is closed and opened along the first direction and is also moved in a second direction substantially perpendicular to the first direction. While the cutter section is moved in the second direction, the motion of the cutter section is controlled at a third speed between the first speed and the second speed.
