ABSTRACT:
An improved vacuum absorption device for use in a glass sheet edge chamfering apparatus is disclosed which is characterized in that rubber plates are installed on the tops of the absorption devices to absorption-secure glass sheets, thereby assuring that the introduction of foreign materials into the absorption device can be prevented, and the horizontal posture of the glass can be maintained through the adjustments of the heights of the absorption devices.
