Patent Images
1. A spiral steamer for fabric webs, comprising:
- a housing that is sealed except for an intake and an outlet;
means for producing and maintaining a steam atmosphere in the housing;
deflecting rollers mounted to rotate in the housing, transversely to the fabric web, the deflecting rollers being arranged in such a way that the fabric web can be guided around the outside of the deflecting rollers in a spiral that has several windings; and
a turning device arranged in the center of the spiral, by which the fabric web can be guided laterally out of the spiral, to the outlet, wherein the contact locations of the fabric web on the deflecting rollers for the bottom segments of a winding of the spiral, in each instance, lie at least approximately on chain lines having suspension points in the region of the apices of the winding in question.
