ABSTRACT:
A method and apparatus for powder sewing two plies of cloth or fabric material by spraying an adhesive powder onto one side of one ply of cloth or fabric from a powder spray gun having a corona discharge electrode mounted thereon. A second pin electrode is provided on the opposite side of the one ply of cloth or fabric. Electrical charges of differing polarity are applied to the electrodes while the cloth or fabric material is moved between the two and powder is sprayed thereon. In the course of migrating through the electrostatic field created between the two electrodes, the powder is caused to follow the force lines created within that field and to migrate onto one side of fabric in the form of a long, narrow band of powder. A second ply of cloth or fabric is then positioned over the first ply and over the band of powder. Pressure and heat applied to the powder activates the powder and causes it to become tacky so that when subsequently cooled, it adheres the two plies together along the narrow powder band.
