Adhesive-free bonding of continuously moving webs to form laminate web and products cut therefrom

ADHESIVE-FREE BONDING OF CONTINUOUSLY MOVING WEBS TO FORM LAMINATE WEB AND PRODUCTS CUT THEREFROM ABSTRACT Method and apparatus for ultrasonically bonding continuously moving webs to one another using a stationary vibrating horn and a relatively slick, non-thermally softenable moving slip layer interposed between the webs to be bonded and the horn to prevent web damage. Interposing the slip layer between the webs to be bonded and the ultrasonic horn improves both the quality and efficiency of web bonding. It reduces friction between the travelling webs and the substantially stationary ultrasonic horn not only due to its relatively slick surface, but also due to the compressive force which the slip layer exerts upon the webs to be bonded. This in turn minimizes jamming and hangups in the very limited clearance existing between the rotating anvil roll and the substantially stationary vibrating ultrasonic horn. In addition, the slip layer maximizes retention of heat either generated in the laminate web by the ultrasonic horn or transferred to the laminate web structure by preheating one or more of the webs. If desired, the slip layer may be comprised of a continuous belt which rotates about the ultrasonic horn. In addition, a secondary slip layer may be provided intermediate the webs to be bonded and the rotating anvil roll to minimize heat transfer from the webs to the anvil roil and to prevent sticking of the webs to the anvil roll. In a particularly preferred embodiment the peripheral edges of the raised anvil bosses are relieved slightly to minimize web tearing and to enhance bond strength. In still another preferred embodiment the anvil roll is heated to a temperature approximating the maximum temperature achieved by the webs being banished to minimize heat transfer from the webs to the anvil roll during the bonding operation. Novel laminate products bonded on-the-fly without the use of an ancillary adhesive may also be produced.

Process and device for positioning a sealing jaw

A first welding plate(1) moves either around a closed track(4) or a linear path and in the welding position lies opposite a support or a second welding plate(6). Two films forming a tubular film are pressed together between the sealing faces(30) of the welding plates by a drive mechanism. The gap(a) between the sealing faces is set by a control unit for the drive mechanism. Gap dimensions are always less than or equal to total thickness of the two film layers lying on each other. When welding plates(1,6) move along a linear path the gap is set by the control unit with the tubular film stationary and welding plates in contact with the film. When the welding plates move around closed tracks(4) the plates move along a straight section(5) with the film during the welding stage and the gap(a) is set by the control unit. The gap may remain constant or vary during the welding stage. Prior to welding the distance(a) can be set to a value equal to or greater than the thickness of both film layers to permit preheating. The gap can then be reduced to exert sealing force. An independent claim is included for a packaging machine, in particular a vertical tubular bag production machine with an electromagnetic linear drive. The drive works on the principle of a suspended railway and comprises a first part and a second part moving relative to the first to vary the gap, which is determined by each position of the moving second part relative to the first part.

Heat sealing apparatus

Un dispositif de scellement thermique comprend un rouleau (3) monté de manière à pouvoir tourner autour de son axe longitudinal (A-A), un organe de scellement thermique (14) monté de manière rotative et définissant lors de l'utilisation un chemin circulaire de mouvement, excentrique par rapport au chemin de mouvement de la périphérie du rouleau (3), et des organes (2, 4) servant à déplacer une bande (6) d'un matériau plastique. Lors de l'utilisation, l'organe de scellement thermique (14) exécute un mouvement périodique interposé entre le rouleau (3) et la bande (6) et ne présente aucune vitesse relative sensible ni par rapport à la bande (6) ni par rapport au rouleau (3) de manière à sceller la bande (6). A thermal sealing device comprises a roller (3) mounted so as to be able to rotate about its longitudinal axis (AA), a thermal sealing member (14) rotatably mounted and defining in use a circular path of movement , eccentric with respect to the path of movement of the periphery of the roller (3), and members (2, 4) serving to move a strip (6) of a plastic material. In use, the heat sealing member (14) performs a periodic movement interposed between the roller (3) and the strip (6) and exhibits no significant relative speed either with respect to the strip (6) or by relative to the roller (3) so as to seal the strip (6).

Welding of thermoplastic materials

The process serves for welding thermoplastic materials according to the hot-melt welding process. In the process, a welding auxiliary material, which is, for example, wound on a drum in the form of strips, is preheated separately from the welding point in a heating device intended for this purpose. The preliminary temperature in this arrangement should be below the welding point or melting point of the material, so that the material still retains sufficient inherent strength. The process has the advantage that, for fusing the materials, that is to say, the materials to be joined and the welding auxiliary material, only a slight temperature increase at the welding point itself is additionally necessary. For welding, the welding auxiliary material (1) is drawn off from the drum (2) by means of an apparatus (7) and pressed onto the materials (3a, 3b) to be welded. The device (7) has a plurality of rolls (16) over which a travelling belt (15) is guided. This apparatus has the advantage that not only is the necessary pressing force achieved, but the weld zone is cooled. <IMAGE>
