Device for treating a band-shaped substrate with a liquid

A device for treating a band-shaped substrate with a liquid, said device comprising:

• a conveying system for conveying the band-shaped substrate, which conveying system comprises a winding system for guiding the band-shaped substrate in a spiral path around the winding system with at least one winding, which winding system comprises first pulley means being rotatable about a first axis of rotation for guiding said at least one winding of the band-shaped substrate through a first angle of deflection around part of the circumference of the first pulley means, and second pulley means for guiding said at least one winding of the band-shaped substrate through a second angle of deflection around part of the circumference of the second pulley means, which second pulley means comprises a second pulley, which is rotatable about a second axis of rotation, for each winding;
• and
• a bath of the liquid, wherein the band-shaped substrate extends through the liquid in the bath over at least part of the length of said at least one winding,
• wherein the second axis of rotation of each second pulley makes an angle α with the first axis of rotation.
