ABSTRACT:
To reduce the polygonal effect, the chain-turning system described in the present disclosure has at least one transition curve (UK11, UK12) that joins up with the circular turning arc (B.11) and the radius of curvature of the transition curve varies continually. This transition curve may join up with a straight portion of the chain's track (G.11, G.12) or with another turning arc. The transition curve may, for example, be a portion of a clothoid, whose radius of curvature at its junction (A.11, A.12) with the turning arc (B.11) is the same as the turning radius and at its junction (C.11, C.12) with the straight portion of the chain's track (G.11, G.12) is infinitely large.
