摘要:
The invention relates to a novel method for bonding plastic capsules (2, 3) for inhalers, to the bonded capsules obtained thereby, and to a device for carrying out said method. The capsules obtained according to the inventive method are disposable capsules and preferably contain an individual dose of a pharmaceutical formulation which can be administered by inhalation, said formulation being in the form of powder or liquid. The shape and function of said capsules enables them to be used in powder inhalers or liquid sprays for the production of aerosols. Aerosols thus produced can be inhaled, for example, so that a pharmaceutical formulation can be administered via the pulmonary route.

Dargestellt und beschrieben ist eine Vorrichtung zum Verschließen des Bodens von aus Packungsmänteln aufgefalteten Verbundpackungen, insbesondere Getränkepackungen. Eine gleichmäßige Erhitzung des zu versiegelnden Bereichs des aufgefalteten Packungsbodens bei gleichzeitig konstruktiv einfachem Aufbau der verwendeten Heizdüse (1) wird dadurch erreicht, daß die Heizdüse (1) einen im wesentlichen der Form des Dornes entsprechenden rechteckigen Querschnitt und mehrere miteinander verbundene Kästen (2, 3, 4) sowie einen Deckel (5) aufweist.
摘要:
Heat sealing apparatus for packaging machinery and particularly suitable for form, fill and seal packaging machinery. The heat sealing apparatus is for forming a continuous lengthways extending seal (29) on a web (18) of packaging material to be fed past it. The apparatus comprises a nozzle (50) connectable to a hot gas producer (62) which produces a flow of hot gas having a substantially constant temperature. The nozzle is mounted on a carrier (52) which is connected with a servo motor drive (56). The servo motor is controlled by a control system (48) so that in use it moves the nozzle relative to the web in accordance with variations in web feed velocity such that the flow of hot gas from the nozzle can apply a substantially constant heat to the web to form the seal (29). The apparatus allows a hot air producer which outputs hot air at a constant temperature and volume flow rate to apply a constant heat along the seal area despite variations in the web feed speed.

Düse (4) zum Schweißen von Kunststoffbahnen oder ―folien mittels eines Heizgeräts (1) mit einer Oberseite (23) und einer Unterseite (24) zur Kontaktierung der oberen bzw. unteren miteinander zu verschweißenden Kunststoffbahn oder ―folie, sowie aus der Oberfläche der Ober- und Unterseite hervorstehende Schleifeinrichtungen, wobei aus den Oberflächen hervorstehende quer zur Schweißrichtung angeordnete Erhebungen (21) am Rand der Luftöffnungen (28) und in Schweißrichtung vor den Luftöffnungen (28) angeordnet sind. Eine derartige Düse (4) erlaubt insbesondere bei Handgeräten eine gute Aufrauung auf der Unterseite der oberen Kunststoffbahn oder ―folie und damit eine wirksame und sichere nachfolgende Verschweißung der Kunststoffbahnen bzw. ―folien in dem Überlappungsbereich.
摘要:
A heating device for heat-sealing bottom portions of containers (11) comprises a primary heater (41) and a secondary heater (42) arranged respectively at a first stop station and a second stop station of bottom forming radial mandrels, each of the mandrels (32) being adapted to carry a tubular blank (11) of rectangular to square cross section as fitted therearound with a bottom forming end portion thereof projecting outward from the mandrel. The primary heater (41) has a primary hot air nozzle. The secondary heater (42) has a secondary hot air nozzle. The primary hot air nozzle is fixedly provided on a phantom outward extension line of the mandrel as halted in the first stop station so as not to interfere with the end portion of the blank fitted around the halted mandrel and having orifices directed toward local parts h, i, j, k of the region of the end portion to be heated. The secondary hot air nozzle is movable on a phantom outward extension line of the mandrel as halted in the second stop station so as to advance into and retract from the end portion of the blank fitted around the mandrel as halted in the second stop station, and has orifices directed toward a plurality of portions uniformly distributed over the entire region a, b, c, d when the secondary hot air nozzle advances.

The invention provides an apparatus for use with containers (11) each in the form of a rectangular or square tube and having an open upper end and an outlet (25) in a top forming portion (12) of the container, for bonding a pour spout (31) on the container edge portion defining the outlet. The apparatus comprises a conveyor (41) for transporting the containers (11) so as to halt the containers successively at a bonding station, and a support (44) movable into contact with the outlet-defining edge portion of the container (11) as halted at the bonding station from inside the container for receiving the pressure of bonding. The support (44) is so disposed as to be movable into and out of the container (11) along an arc path and has a contact face (83) facing outwardly of the arc path.
摘要:
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung eines kontinuierlichen Folienschlauchs aus einer ebenen Folienbahn, die durch eine Formeinrichtung zu einem längsseitig offenen Folienschlauch mit sich überlappenden Folienrändern geformt wird, wobei der Folienschlauch kontinuierlich einer Siegeleinrichtung zugeführt wird, welche die sich überlappenden Folienränder längsseitig miteinander verschweißt. Die Erfindung zeichnet sich dadurch aus, daß das Verschweißen der Folienränder in der Siegeleinrichtung berührungslos durch Heißluft erfolgt.
摘要:
An apparatus and method is disclosed for bonding a fiber reinforced plastic automotive body member (44) to a reinforcement member (46). An adhesive (56) is located between mating surfaces of the body member and the reinforcement member. Pressurized heated and cool air is used to heat and facilitate the cooling of the adhesive. The apparatus includes a switchable heating and cooling system that first provides pressurized heated air about outer surfaces of the body member and the reinforcement member, and thereafter, the system provides pressurized cool air about the same outer surfaces.
摘要:
A hot gas heating device is disclosed which is used for heating an upper open end region of a tubular body (7) prior to it being heat-sealed. The device comprises a nozzle housing (1) including a casing (2) accommodating a heating nozzle (3) in a cavity (4). The nozzle (3) can adopt a predetermined position within the tubular body (7) so that a hot gas outlet (12) extending circumferentially around said nozzle can deliver hot gas to an upper inner wall region of said tubular body, thereby softening the material of the tubular body in that region. The nozzle housing (1) further comprises a cooling and centering ring (6) surrounding the outer side of said upper inner wall region of the tubular body. The heating device is also provided with means (18, 19, 20, 21) for exhausting the applied hot gas. In order to allow for more uniform heating of the intended weld site, the means for exhausting the applied hot gas are arranged so as to control the applied hot gas flow by creating a substantially uniform pressure drop around the upper wall region of the tubular body (7), thereby creating a uniform distribution of the hot gas on the inner wall region of the tubular body. Preferably, said means is in the form of a gas ejector.
