FIELD: glass industry.
SUBSTANCE: invention relates to a lifting device for lifting a heated glass sheet in a glass bending system and comprises an array of lifting jets, containing peripheral outlets of lifting jets and internal outlets of lifting jets located inside relative to peripheral outlets of lifting jets. Each outlet of lifting jet is designed so that to enable gas flow in direction of glass sheet. Lifting device also comprises lifting jets release operation control unit, which makes it possible to start operation of at least one of inner outlets of lifting jets before operation of at least one of peripheral outlets of lifting jets. Lifting device is arranged under conveyor rollers.
EFFECT: technical result of invention is exclusion of gas flow between glass sheet and molding tool.
