Claims (11)

For providing unfastened guidance of a reclosed bag with fastened elements fastened therein and positioned between the pair of opposing plies of the folded web of the back film for providing unfastened guidance of the back film through the forming reservoir. In the guide mechanism, the guide mechanism includes a first guide coupled to an inner surface of the back film, a second guide coupled to a pair of fastening fastener elements on opposite plies or more of the back film, and the fastening fastener as the back film advances. 9. A guide mechanism for a back film having fastener elements, comprising separating means located along a path of travel of the back plume for separating elements, and first and second guides, support arms for supporting the separating means. The guide mechanism of claim 1, comprising a bracket member connected to the support arm, wherein the first and second guides include first and second guide wheels rotatably mounted on the bracket. . 3. The method of claim 2, wherein the first guide wheel engages the inner surface of the back film, the second guide wheel has a sloped surface for engaging the fastener elements fastened on opposite plies of the back film, and having a rotation axis. The first and second guide wheels are usually perpendicular to the surface of the back film. The forming, filling and sealing packaging device has a tubular shape with fasteners capable of fastening and reclosing at each opposite ply of the film to provide a means for applying a continuous plastic back film and to apply a predetermined amount of product to the back film. Means for applying the film through the fill reservoir and a guide mechanism positioned within the back film and directly transporting the fill reservoir to provide unobstructed guidance of the film through the fill reservoir, wherein the guide mechanism includes a fastener element. Bag assembly with separating means for separating, a support arm for supporting the printing mechanism and the separating means, means downstream of the filling reservoir for pressing the fastener elements together in a fastening relationship, and first and second side seams Means for sealing the back film laterally to form an assembly from the back film; It means to form, fill, and seal packaging apparatus comprising the for. 5. An apparatus according to claim 4, wherein the guide mechanism comprises first edge means for engaging the inner surface of the back film opposite the fastener element and second edge means for engaging the fastener element. 6. The apparatus of claim 5, wherein the first and second edge means comprise first and second stop edge means each having a tapered front portion. 6. The method of claim 5, wherein the first edge means comprises a first guide wheel having an axis substantially perpendicular to the plane of the back film and the second edge means having a second guide wheel having an axis substantially perpendicular to the plane of the film. Apparatus comprising a. 7. The apparatus of claim 6, wherein the first guide wheel engages the inner surface of the back film, the second guide wheel engages the fastener element and the second guide wheel has an inclined fastener element engagement surface. . 9. An apparatus according to claim 8, wherein the support arm comprises a separating means that directly follows the guide wheel and extends between the fastener elements and the bracket member is connected to a support arm for rotatably supporting the guide wheel. 8. The apparatus of claim 7, wherein the first and second guide wheels comprise sloped surfaces having axes substantially perpendicular to the plane of the back film. 2. The separating means of claim 1, wherein the separating means comprises a separating edge disposed on the support arm and the first and second guide wheels are positioned to directly advance the separating edge, the separating means being disposed on the supporting arm. Characterized in that the device. ※ Note: The disclosure is based on the initial application.
