Abstract
An improved assembly for forming a plurality of individual packages, containing articles, such as crackers or the like therein. The assembly includes a first roller member and a second roller member which is mounted in cooperative relationship with the first roller member. Each of the roller members includes cooperating members for simultaneously heat sealing, crimping and transversely severing a tubular strip containing the crackers in order to form the individual packages containing the crackers. The improvement includes a slitter member mounted on each of the sealing, crimping and severing members carried by the first roller member. The slitter members slit the film along the end portions. A cooperating element is provided in the sealing and severing member carried by the second roller member for holding the film in place while the slitter member cuts the sealed end portions of each of the packages to provide slits in the packages which penetrate through the outer edges of each of the packages, but not the package interior, in order to provide for easy opening thereof.
