Abstract
A guide chain for carrying lines that supply all types of expendable material from a fixed connection to a movable consuming device. In order to provide the guide chain with a periphery that is as completely closed as possible and has as smooth a surface as possible, and in order to be able to assemble the individual parts in a straightforward manner, two basic variants are proposed. In one variant, recesses are provided in the side pieces and are respectively concentric to a pivot axis between that side piece and an adjacent side piece, with externally circular cylindrical cover elements being inserted in the recesses to cover horizontal gaps between adjacent chain links. Caps are provided to connect adjacent side pieces, with each cap having a concentric rim that extends into the recesses and grooves that interconnect the latter. Each cap also has projecting members that are disposed between stops of adjacent chain links. These projecting members limit the maximum pivot angle of adjacent chain links.
