Device for treating the edge zones of plate-shaped elements

In a device for the treatment of the edge zones of surfaces of plate-shaped elements, comprising an upright lateral supporting wall (1) for the elements, which lateral are arranged substantially upright, conveying means (3) for the elements at the bottom edge of the supporting wall (1), a treatment tool (17) guided to be displaceable upward and downward along a substantially vertical guide rail (19) connected to a stand (20) of the device;

• there being a substantially vertical slot (14) in the supporting wall (1) opposite the treatment tool (17), and a bracing roll (15) rotatable about a substantially vertical axis (16) and at least partly penetrating said slot (14) in the supporting wall (1);
• said wall extending on both sides of said slot, and the bracing roll being opposite the treatment tool so that the pressure exerted by the treatment tool on a said element is absorbed by the bracing roll;
• the improvement comprising a carrier unit (8) for the plate-shaped element (2), said carrier unit being disposed between the lower end of the supporting wall (1) and the conveying means (3) and on the side of the plate-shaped element which is opposite the treatment tool (17), the carrier unit (8) being guided in parallel overlapping relationship to the conveying means (3), whereby said plate shaped element (2) is supported by both said carrier unit (8) and said conveying means (3), and means for at least intermittently moving the carrier unit in synchronism with the conveying means (3).
