Claims13
A device for applying foam to textiles, comprising:
- a source of foam;
- an applicator joined to said source for receiving foam therefrom, said applicator comprising first and second portions separated by an apertured plate, said first portion being joined to the source for receiving foam therefrom, said foam being spread across the applicator by the plate and passing through the apertures therein to said second portion, said second portion containing porous material and having a configuration which converges towards an elongated discharge orifice whereby said foam is uniformly distributed across the orifice.
A device for applying foam to textiles, comprising:
- means for mixing liquid and air to develop a jet of the mixture;
- a foamer joined to the mixing means for receiving said jet, said foamer including porous material through which the mixture passes to produce a foam having a desired bubble size;
- an applicator joined to said foamer, said applicator comprising first and second portions separated by an apertured plate, said first portion being joined to the foamer for receiving foam therefrom, said foam being spread across the applicator by the plate and passing through the apertures therein to said second portion, said second portion containing porous material and having a configuration which converges towards an elongated discharge orifice whereby said foam is uniformly distributed across the orifice.
