DEVICE FOR TREATING A BAND-SHAPED SUBSTRATE WITH A LIQUID

摘要

A device for treating a band-shaped substrate with a liquid, including: a conveying system including a winding system guiding the band-shaped substrate in a spiral path around the winding system with at least one winding; a first pulley rotatable about a first axis of rotation guiding the at least one winding of the band-shaped substrate through a first angle of deflection around part of the circumference of the first pulley, and a second pulley guiding the at least one winding of the band-shaped substrate through a second angle of deflection around part of the circumference of the second pulley, which is rotatable about a second axis of rotation, for each winding; and a bath of the liquid. The band-shaped substrate extends through the liquid over at least part of the length of the at least one winding. The second axis of rotation of each second pulley makes an angle alpha with the first axis of rotation.
