Abstract

The invention relates to a vacuum bell carrier wherein negative pressure in an operating aperture (42) is provided by passing compressed air through a Venturi channel arrangement (22, 32). By expansion of the air between two jet bodies (18, 30), the flow rate is increased to create a vacuum.
