PRODUCTION OF ONE-PIECE STEMWARE FROM GLASS, ETC.

摘要

Glass or like stemware is manufactured in one piece by part-forming an article having a glob of material in the position where the stem is required, placing the glob between rollers which have a shape defining the required shape of the stem, and rotating the glob between the rollers while advancing the rollers inwardly. Subsequently a foot forming member is axially advanced towards the glob to apply pressure against the glob to form a radially-extending foot.
