Abstract

A ring-like member for use in lifting a glass sheet from a given path to the vicinity of a vacuum holder at a shaping station has its movement coordinated mechanically with stop means that engages the leading edge of a glass sheet at an edge locating position when said ring-like member is below said given path and mechanically retracts from said edge locating position in unison with said ring-like member when said ring-like member moves in the direction of the thickness of said glass sheet to engage and lift said glass sheet. This mechanical coordination of movements avoids rubbing the glass sheet edge in the direction of the glass sheet thickness during its lifting without requiring complicated and expensive coordinating equipment.
