Abstract
A rail element conveys suspended objects, such as bottles or preforms. The rail element includes two guide rails which are separated by a pre-defined distance and which form lateral support surfaces for the objects being conveyed along a conveyor passageway, such as preform sub-neck guides. A helically-curved conveyor section consists of a frame on which the guide rails are helically arranged. At least one guide rail includes a flat band that can be removed from the frame.
