Cathode-ray tube glass parts (cones and face-plates) are turned out at the rate of one every six seconds by a new automatic plant put into operation by Pilkington Brothers at St. Helens this year. The firm came into the business at the Governments request in I948 and now, with the new equipment, are able to produce at least two million components a year. In this machine, large blobs of molten glass from a furnace are fed into moulds on a rotating table, and this passes under a plunger which descends and presses out the glass to the required shape. Annealing follows, then inspection, and grinding and polishing where necessary.
