The invention relates to a device for making a sealing connection between two material layers containing plastic, especially in a product packing pouch (2), having at least one sealing station (3), comprising at least two sealing jaws (4a, 4b) situated opposite each other and movable between an open position and a sealing position, having respectively a sealing surface (5a, 5b) on their inner side facing toward the other respective sealing jaw (4b, 4a), wherein the sealing station (3) is configured such that in the open position at least two material layers (6, 7, 8) to be joined together by sealing can be arranged between the sealing jaws (4a, 4b) and in the sealing position the material layers (6, 7, 8) can be pressed together. It is proposed that at least one of the sealing jaws (4a, 4b) comprises at least one lubricant channel (9) and the device (1) comprises a lubricant delivery device (10), which is configured to direct a lubricant through the lubricant channel (9) toward the sealing surface (5a, 5b) of the sealing jaw (4a, 4b) and/or toward the sealing surface (5b, 5a) of the oppositely situated sealing jaw (4b, 4a).

A frangible laminate includes first, second and third webs, and the second web is positioned between the first and third webs. The forming of the frangible laminate includes adhesively bonding a first plurality of sections of the second web to the first web, applying release material in order to inhibit at least some of any bonding between the first plurality of sections of the second web and the third web, and adhesively bonding a second plurality of sections of the second web to the third web. The frangible laminate is separated into a first laminate and a second laminate, so that the first laminate includes the first web and the first plurality of sections of the second web, and the second laminate includes the third web and the second plurality of sections of the second web.

Plate packs are produced from a sheet-like starting product (1), which is cut to form plates, which are stacked to form a plate pack. The plates within the plate stack are joined to one another by a bonding agent. The bonding agent used is a cyanoacrylate adhesive with a high temperature stability rating. It is applied to a wetting layer (14) for the adhesive. The wetting layer (14) is formulated to a pH in a region >7. The cyanoacrylate adhesive with a high temperature stability rating is able to spread on the wetting layer (14) such that effective wetting takes place, thus achieving quick and secure joining of the plates to one another.

The present invention is a method for manufacturing inflatable articles, or bladders for inflatable articles, that is time-efficient, simple, inexpensive and permits the uninterrupted manufacture of numerous and even customized article or bladder configurations and sizes, without expensive configuration-specific, metal tooling. The method includes the steps of applying a barrier material to a side of a first film, providing a second film with the first film so that the barrier material is disposed between the first and second films, adhering the first film to the second film so that the films are sealed together in areas except where the barrier material has been applied to form at least one inflatable compartment and sealed peripheral edge, and cutting along the sealed peripheral edge to form an inflatable article or bladder for use in an article of manufacture. The barrier material may be a paint, ink, paper or surface treatment that effectively prevents the first film from adhering to the second. The inflatable article or bladder of the present invention may be used as or in athletic equipment, for example, including footwear.

The method includes applying a fluorinated fluid to at least one of a surface of an object or an adhesive surface on an adhesive article, positioning the adhesive surface to face the surface of the object such that the fluorinated fluid is between the surface of the object and the adhesive surface; and removing at least some of the fluorinated fluid to permit bonding between the surface of the object and the adhesive surface. The fluorinated fluid generally facilitates the repositioning of the adhesive surface on the surface of the object before removing the fluorinated fluid. A kit comprising an adhesive article and a container including a fluorinated fluid is also described.
