摘要

Rope pulley (6) comprises base rollers rotating about the pulley axis and an intermediate piece (8) held centrally on one of the base rollers. The intermediate piece has a rope pulley on a peripheral surface concentrically surrounding the roller axis. An independent claim is also included for a method for producing a roper pulley. Preferred Features: An intermediate piece is formed by one length of a tubular or hollow cylindrical profile. The base rollers each have a rope pulley. The intermediate piece has centering surfaces (11) on both ends and lie with the centering surfaces on a counter surface (12) of one base roller in relation to the roller axis.
