摘要

The partial unit of a positioning drive comprises a partially curved guidance rail (1) in which chain links (2) move in both directions. The chain links have projections (2a) and matching recesses (2b) into which the projections extend. The chain links also have holes (2') passing through them that pass through projections (2asterisk) on the inner radius side of the guide rail and form a continuous path.
