Apparatus for guiding a flexible member

A system for guiding a flexible member, the system comprising:

• a first apparatus further comprising:
• a first drum mounted for rotation about a first drum axis;
• and
• a first pulley mounted for rotation about a first pulley axis being spaced from and inclined relative to the first drum axis in an arrangement in which the shortest imaginary line extending between the first drum axis and the first pulley axis is perpendicular to each of the drum axis and the first pulley axis and lies substantially in a fixed first pulley diametric plane;
• wherein the first apparatus defines a first portion of a path for the flexible member, the first portion of the flexible member path including in sequence a first drum wrap portion around a first part of the first drum circumference on a first fixed drum diametric plane perpendicular to the first drum axis, a first connecting portion between the first drum and the first pulley, a pulley wrap portion around part of the first pulley circumference on the fixed first pulley diametric plane and perpendicular to the first pulley axis, a second connecting portion between the first pulley and the first drum, and a second drum wrap portion around a second part of the first drum circumference on a second fixed drum diametric plane perpendicular to the first drum axis and axially spaced from the first fixed drum diametric plane;
• a second apparatus further comprising:
• a second drum mounted for rotation about a second drum axis;
• and
• a second pulley mounted for rotation about a second pulley axis being spaced from and inclined relative to the second drum axis in an arrangement in which the shortest imaginary line extending between the second drum axis and the second pulley axis is perpendicular to each of the drum axis and the second pulley axis and lies substantially in a fixed second pulley diametric plane;
• wherein the second apparatus defines a second portion of the path for the flexible member, the second portion of the flexible member path including in sequence a first drum wrap portion around a first part of the second drum circumference on a first fixed drum diametric plane perpendicular to the first drum axis, a fourth connecting portion between the second drum and the second pulley, a pulley wrap portion around part of the second pulley circumference on the fixed second pulley diametric plane and perpendicular to the second pulley axis, a fifth connecting portion between the second pulley and the second drum, and a second drum wrap portion around a second part of the second drum circumference on a second fixed drum diametric plane perpendicular to the second drum axis and axially spaced from the first fixed drum diametric plane;
• and
• a third connecting portion between one of the first and second drum wrap portions of the first drum and one of the first and second drum wrap portions of the second drum.
