Abstract
Abstract A glass grinding machine for dressing the edges of glass windowpanes is provided comprising a motor-driven turntable having releasable clamping means automatically coordinated with the movement of the turntable for holding said windowpanes during grinding thereof; a working station provided at the periphery of the turntable and having a rotating grinding wheel movably mounted and controlled by a templet guiding means corresponding to a predetermined contour; a feed station provided at the turntable periphery and having feed means automatically coordinated with the turntable movement for depositing the windowpanes continuously fed for the grinding operation into one of said clamping means; a removal station provided at the turntable periphery and having removal means operating automatically in coordination with the turntable movement for the removal of the ground windowpanes from one of the clamping means, the feed and removal means having a swinging arm driven in coordination with the turntable and provided with means for holding one windowpane each; a swinging arm mounted for rotation about the axis of rotation of the turntable and having on its free end extending beyond the radius of the turntable a rotatably mounted beam having both of its ends positioned at a feed station and at a removal station, respectively, when the beam is oriented radially with regard to the turntable, said beam being equipped with glass pane holding means, a driver connected with the turntable shaft to produce a temporary synchronization of said swinging arm and turntable; a drive for rotating the beam by 180* about its axis of rotation on the swinging arm; and a rotatory drive for rotating the swinging arm independently of the synchronization of the turntable and swinging arm at a velocity exceeding the speed of rotation of the turntable.
