Profilkette

Profilkette is a German term that translates to “profile chain” and is used in several technical domains to denote a linked sequence of profiles or profile-like elements. The exact meaning varies with the field, and the term is mainly found in specialized texts.

In mechanical engineering and manufacturing, a Profilkette can describe a chain or belt where the individual links or segments include profiled surfaces. Such profiles improve engagement with guides, rollers, or sprockets and can enable precise guidance, higher load capacity, or compatibility with non-standard geometries. Design considerations for a Profilkette in this sense include the geometry of the profile, choice of material, lubrication, wear resistance, and tensioning.

In surveying, civil engineering, and geomatics, Profilkette refers to a sequence of cross-sectional profiles along a linear alignment, such as a road, railway, or river valley. Each profile records horizontal position and vertical elevation; the series forms a profile chain used for route design, earthwork estimation, and 3D visualization. The concept is often implemented in CAD or GIS workflows, where profiles are interpolated and analyzed to derive cut-and-fill volumes and longitudinal profiles.

In data and software contexts, the term may appear informally to describe a linked set of user or device profiles used for analysis or personalization, but this usage is not standardized.
