Abstract
A guide chain with supporting link chains including chain links which are connected by crosspieces. To limit the mutual pivot angle, each chain link is provided with slots which extend about a common pivot axis, with engaging studs of an adjacent chain link extending into the slots. In order to facilitate assembly and improve the support capability of the guide chain, each chain link is made as one piece, is provided at one end, on one side, with a disc-shaped plate in which are disposed the slots, and is provided at the other end, on the opposite side, with a cup, on the bottom of which are formed the engaging studs. The diameter of the plate is less than the diameter of the cup, so that the plate of one chain link can be placed into the cup of another chain link.
