The shoe is used as a glass plate pressing or backing-up member attached on a conveyor of a glass plate edge bevelling machine. The shoe comprises an elongate body. On one face thereof the elongate body is provided with blocks adapted for abutment engagement with large plate glass workpieces to be processed. A small supporting plate member movably connected to the elongate body is positionable at a first position, whereat the small plate member defines an extension of the elongate body, adapted for engagement with and for pressing or backing-up small size plate glass workpieces to be processed. The small plate member is further positionable at a second idle position, whereat it is accommodated within the elongate body in association with the blocks, without interfering with larger glass workpieces to be supported by the elongate body.
