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.

Abstract: Apparatus for conveying articles along a path of travel, the articles being of the type having an upper portion for being supported by the apparatus, a lower portion for being suspended from the apparatus and a low-angle transition portion therebetween, the apparatus comprising in combination a conveyor defining a path of travel along its length with neck rails for receiving the upper portions of the article to be conveyed, a pressure source operatively coupled to the conveyor to move the received articles to be conveyed, and control brushes coupled with respect to the conveyor along at least a portion of the path of travel to contact the lower portions of the bottles while being moved for providing a rearwardly directed angle to the articles to thereby abate the forward and rearward swinging of the articles.
