Abstract
The invention relates to a process and an apparatus for spreading a moving web of textile material during a treatment by means of fluid streams directed from the middle to the edges of the web. The side edges of the web are probed by sensors which control the fluid streams directed onto the associated edges of the web. In this way, reliable spreading is obtained with minimal outlay, even with different webs of textile material and under varying working conditions.
