摘要:
A lightweight vacuum pickup is constructed using a honeycomb platen as the sheet engaging member of the pickup. The cells of the honeycomb platen are selectively sealed to control the amount of vacuum drawn through the platen. When used to transfer heat softened glass sheets, the lower sheet engaging surface of the platen is sealed with a dense material cloth which restricts airflow therethrough. The cloth includes holes positioned within the periphery of the glass sheet to be engaged by the pickup.
