Abstract
A cathode ray tube faceplate press having an indexing table rotatable around a column normal to the table and having circular array of female molds concentric with the column. Index speed of the table is optimized by a barrel cam drive cut to provide smooth acceleration and deceleration which can be tolerated by the molten glass in the molds. A cam dwell precisely registers the table work stations avoiding the need for register pins and the delays they introduce. Acceleration and deceleration peak at about the one-eighth and seven-eighths position of the drive cycle following a generally sinusodial form.
