Abstract
The application of liquid to a moving fabric is effected by delivering same to a rotatable spinning disc which centrifugally impels the liquid against the fabric. This action overcomes surface tension causing the liquid droplets to break up into a fine mist so that a large area of fabric is wetted with an amount of liquid which is substantially less than the fabric weight. Also, the velocity imparted to the liquid droplets in mist forms enhances absorption of the liquid by the fabric.
Claims9
An apparatus for applying liquid to a moving fabric, comprising:
- a fabric treatment chamber;
- roller means within the treatment chamber for guiding the fabric passing through the chamber so that the fabric follows at least one vertical path;
- a plurality of adjacent side-by-side liquid delivery spinning discs rotatable about vertical axes, the discs being arranged across a width of the fabric adjacent the at least one vertical path;
- a delivery pipe mounted directly above a center of each spinning disc for supplying liquid to each disc, the spinning discs centrifugally impelling the liquid in the form of a fine mist-like spray uniformly across the fabric width with each spinning disc forming a pattern on the fabric;
- a baffle located at each side of each spinning disc and being between adjacent spinning discs to control a degree of overlap between the spray patterns created by adjacent spinning discs, the baffles of each spinning disc being diametrically opposed and longitudinally displaced relative to one another in the direction of the fabric width;
- and
- means for adjustably mounting each baffle relative to its spinning disc to permit the baffle to be adjusted so that each baffle can be moved closer to or further away from its disc and can also be moved lateral to its disc in the widthwise direction of the fabric to permit variation of spray pattern overlap control.
