Abstract
An air-conveying apparatus for moving articles along a path of travel at varying speeds comprises in combination a pneumatic conveyor for supporting the articles, a fan operatively coupled to the conveyor to provide air under pressure to the pneumatic conveyor to convey the articles there along, a damper to restrict the flow of air through the fan, and a controller responsive to a signal to vary the positioning of the damper and thereby vary the flow of air through the fan and consequently vary the speed of the articles being conveyed.
