ABSTRACT:
The conveying apparatus is formed by two conveying sections which are arranged one behind the other, and are in the form of spirals that wind around a center such that the windings of the two conveying sections are nested one inside the other. Each spiral conveying section has a stationary guide surface which supports the articles to be conveyed on a surface that faces outwardly away from the center. Each spiral conveying section also includes a conveying system, that has at least one endless, flexible conveying element which is driven such that it circulates around the conveying section. The conveying element acts on the outer side of the articles to be conveyed. There is also an endless flexible support member between the articles to be conveyed and the guide surface, that circulates around the spiral conveying section, and is in the form of a band that overlays the guide surface. The support member is carried along by the articles being conveyed.
