Abstract

A roller conveyor has an aligning device for glazing panes. The conveyor includes a plurality of aligned rollers forming a roller bed and driven for advancing glass panes in a conveying direction. The aligning device includes a rail disposed above the rollers and mounted such that it extends at a small horizontal angle to the conveying direction. The rail is disposed relative to the rollers such that an edge of a pane being conveyed on the rollers engages the rails so as to align the pane. The aligning device also includes a ring disposed in the roller bed downstream of the rail in the conveying direction. The ring has an external diameter larger than that of the rollers and is positioned relative to the rail such that the ring can engage a lower surface of a pane conveyed on the rollers at a position spaced from the center of gravity of the pane, and so rotate the pane.
