Abstract
In the continuous treatment of webs of material with a treatment medium to be applied to the web of material, especially for dying, wherein foam containing the treatment medium is applied to the web material and is subsequently worked into the web of material, the foam is applied to the circumference of a revolving cylinder, by wiping it off to a defined layer height and the web of material caused to run freely onto the cylinder and the web is looped around the cylinder freely through a given angle.
Claims13
Apparatus for the continuous treatment of webs of materials comprising:
- (a) a revolving cylinder, the length of which corresponds at least to the width of the web of material;
- (b) means for directing the web of material onto the circumference of said cylinder at an entry point and freely looping said material around said cylinder through a loop angle;
- (c) foam feeding means for transferring foam, in a transfer zone, over the length of the cylinder, directly against the circumference of the cylinder;
- (d) a wiper disposed parallel to the cylinder axis following said transfer zone and spaced from the circumference of said cylinder to form a foam layer of predetermined thickness on said cylinder, said wiper being followed in the direction of rotation by said entry point;
- and
- (e) said mean for directing including, as the last guide of the web of material before reaching said entry point, a guide roll, the circumference of which is spaced from the circumference of said cylinder a distance which exceeds the total thickness of the foam layer and the web of material.
