Abstract

A guide rail, and method of making same, for the guiding and/or tightening of chains that are used in internal-combustion engines, for example, for driving camshafts, auxiliaries or the like is disclosed. For reasons concerning weight and manufacturing, the guide rail consists of a plastic material and is formed by a slideway lining body and a carrier. Both the carrier and the slideway lining body are produced in a progressive manufacturing cycle and are interconnected via one or several dovetailed connections.
