Hot glass panes are displaced without sagging through a treatment station, such as an oven, on a roller grate which is linearly reciprocated while the rollers of the grate receive a translatory angular velocity component and an angular oscillation so that the velocity at a glass pane relative to the traveling grate is Rx omega osc+Rx omega trans, where R is the radius of the rollers at a point of contact with the pane, omega osc is the angular oscillation velocity component of the roller displacement and omega trans is the angular translatory component. |
