Abstract: An apparatus and methods for producing at extremely high production speeds small pouches filled with tobacco or other granular, powdered or solid content. An endless web substrate, with or without flavor film thereon, is formed into a tubular shape with a longitudinal seam. The tube is cut to individual lengths, and a procession of tubes is crimp-closed at one end, filled and crimp-closed at the other end to complete pouch production. During production, the seams formed at the crimped ends of the pouch are parallel to one another and the longitudinal seam of the pouch is midway between the sides of the pouch and orthogonal to the seams formed at the crimped ends of the pouch.
