Abstract: A glass trimming cutter for working the edges of glass panes is disclosed. The cutter includes a horizontally arranged, motor-driven rotary table having releasable gripping devices for temporarily securing glass panes in position. One or more peripheral cutting wheels is movably supported at the periphery of the rotary table which wheel is controlled by a template guide. A feed conveyor horizontally supports glass panes to be worked and a discharge conveyor horizontally supports worked glass panes. A loading and unloading device operates automatically in dependence upon the movement of rotation of the table. The loading and unloading device has a support device which can be moved between a first position above the feed conveyor, a second position above the rotary table and a third position above the discharge conveyor. The rotary table has an axis of rotation arranged along longitudinal central planes of the feed conveyor and along longitudinal central planes of the discharge conveyor.
