摘要:
A V-grooved composite insulation is provided with an adhesive coating and a protective jacketing material bonded to the adhesive. The protective jacketing material extends beyond the perimeter of the grooved insulation board and comprises at least one intact release layer at a location in which the protective jacketing is clear of contact with the bottom surface of the insulation member and a pressure sensitive adhesive between the portion of the protective jacketing material and the at least one release layer. The method also comprises preshaping the grooved insulation board around a pipe by bending the grooved insulation board, removing the release layer of the protective jacketing material, thereby exposing the pressure sensitive adhesive and securing the pressure sensitive adhesive to the protective jacketing to thereby surround the pipe in a vapor free manner. Grooved insulation boards with protective jacketing so constructed are also provided.

A method for producing a clad duct from a laminate comprising a rigid foam insulation panel (12) bonded to a sheet of thermoplastic material (14), said method comprising the steps of heating a portion of the sheet of thermoplastic material (14) in the vicinity of a first V-shaped groove (20) produced in the foam insulation panel until that portion of the sheet (14) becomes pliable, bending the sheet (14) where the sides of the first V-shaped groove (20) intersect until the V-shaped groove (20) closes, cooling the sheet (14) to or below a temperature at which the sheet retains its bent shape, repeating the heating, bending and cooling steps for a second V-shaped groove (20), and any additional V-shaped groove (20), and sealing a first edge (22) and a second edge (22) of the laminate. A special heat brake serves to heat the sheet of thermoplastic material.

An object of the present invention is to provide a method for producing a pressure-sensitive adhesive tape package suitable for mass production. The production method according to the present invention aims at producing a pressure-sensitive adhesive tape package which is a pressure-sensitive adhesive tape package 10 accommodating a pressure-sensitive adhesive tape 14 having a support 18 and an adhesive agent layer 12 provided on one surface of the support 18, the pressure-sensitive adhesive tape package comprising a release sheet 16 to which the adhesive agent layer of the adhesive tape is releasably attached. In this method, the adhesive tape 14 is bonded to the release sheet base material 116, and folded in two. Subsequently, a plurality of adhesive tapes 14 is heat sealed and temporarily attached to one release sheet base material 116, and the release sheet base material 116 is cut.

Ein Auskleidungsschlauch (1) zur Auskleidung von Rohrleitungen, der einen Innenfolienschlauch (2) und eine auf dem Innenfolienschlauch (2) angeordnete Lage aus Fasermaterial (4) umfasst, welches mit einem durch UV-Licht härtbaren Reaktionsharz getränkt ist, wobei der Innenfolienschlauch (2) ein styroldichtes, thermisch verschweißbares Trägermaterial (6, 6a, 6b, 6c) enthält, das auf seiner dem Fasermaterial (4) zugewandten Außenseite eine aufkaschierte Vliesschicht (8) aufweist und das einen sich entlang des Innenfolienschlauchs (12) erstreckenden Überlappungsbereich (12) umfasst, in welchem die Randabschnitte (10a, 10b) des Trägermaterials (6, 6a, 6b, 6c) thermisch miteinander verschweißt sind, zeichnet sich dadurch aus, dass die Vliesschicht (8) auf der Außenseite des radial innen liegenden unteren Randabschnitts (10a) im Überlappungsbereich (12) thermisch mit dem Trägermaterial (6a) an der Unterseite des radial außen liegenden oberen Randabschnitts (10b) verschweißt ist, und dass der radial außen liegende obere Randabschnitt (10b) im Überlappungsbereich auf seiner Außenseite eine Struktur (22) aufweist, welche ein dauerhaftes Anhaften von Reaktionsharz ermöglicht. Die Erfindung betrifft weiterhin ein Verfahren zur Herstellung eines solchen Auskleidungsschlauchs.
摘要:
The present invention relates to a moist, layered bioadhesive patch comprising one or more polymers. Moreover, the invention relates to a method of producing a monolayered film and a method of drying said film. Additionally, the invention relates to methods of producing bioadhesive, layered patches by combining layers of the monolayered film to obtain a desired thickness of the patch. Patches according to the invention may be used as such, or for delivering pharmaceutically active compounds, such as in a drug delivery system.
