Abstract (en)
[origin: ES8308739A1] A process and apparatus for the control of the path of the grinding tool of an all-around edge grinding machine supporting a glass pane for movement about a rotational axis. The grinding tool is positively guided into contact with the edge of the glass pane as controlled by the contour of the glass pane. A scanning roller, also guided into contact with the edge of the glass panel provides the control heretofore described. Both the grinding head and scanning roller are movable in a direction toward the rotational axis of the glass pane. Path signals determined by the scanning roller are stored in a sliding register, and delayed at its output for a period of time required for movement of the glass pane through an angle which corresponds to the rotational angle ( alpha , beta ) between the point of contact of the scanning roller and the point of contact of the grinding tool on the edge of the glass pane. The path signals from the sliding register are used in position controlling the grinding tool. The scanning roller and the grinding tool each may be disposed on a sled for movement in directions colinear with a radius from the axis of rotation of the glass pane. The scanning roller and the grinding tool each may be disposed at the end of a rocker arm for movement along a circular path.
