摘要:
The bonding device (1) includes a base portion (2), the nozzle (10) discharging adhesive, an upper roller (12) and a lower roller (18) that clamp and feed an upper sheet (C2) and a lower sheet (C1), a lower feed arm (7) rotatably supporting the lower roller (18), a lower roller base (35) holding the lower feed arm (7), and an adjustment mechanism (700) that adjusts an attachment position of the lower roller base (35). The adjustment mechanism (700) includes a first shaft portion (71) extending from a fixing face of the base portion in a perpendicular direction, and a rotating member (73) having a first hole portion (738), into which the first shaft portion (71) is inserted, extending in parallel to the perpendicular direction, and being capable of rotating around a rotation axis that is eccentric with respect to the first shaft portion (71). The distance between the upper sheet (C2) and the nozzle (10) does not change as a result of the lower roller base (35) moving in the up-down direction.

Eine Vorrichtung (1) zum Verschweißen von mindestens zwei übereinander liegenden Bahnen (2), die zwei Presselemente (3, 4) aufweist, welche zwischen sich einen Pressspalt (5) bilden, durch den die Bahnen (2) geführt werden. Zusätzlich ist die Vorrichtung (1) mit einem Laser (7) versehen, der so angeordnet ist, dass er Laserstrahlung (8) unter Durchstrahlung des ersten Presselementes (3) und des Pressspalts (5) in Richtung des zweiten Presselementes (4) abgibt. Erfindungsgemäß wird das zweite Presselement (4) von einem elastisch gelagerten blechartigen Abstützelement (9) gebildet, welches die Bahnen (2) im Pressspalt (5) federnd in Richtung des ersten Presselementes (3) beaufschlagt.
摘要:
The invention is a rotatable cylindrical roll for heat sealing heat sealable materials (15) that includes a heating zone (17) for sealing the material and a cooling zone (19) for supporting the newly formed seal. The device (10) comprises a conductive zone (25) and a resistive zone (20) that are in electrical communication. The resistive zone (20) comprises a cylindrical member having a circumferential band (40) of resistive material disposed on its surface. The conductive zone (25) comprises a cylindrical member having a plurality of conductive strips (50) extending laterally across its surface that are in electrical communication with the resistive band (40). Current is applied via a brush to the conductive strips (50). Current flows from the conductive strips (50) into the resistive band (40) and exits through a conductive strip that is in contact (32) with a ground. Current path through the resistive band (40) defines the heating zone (17), and the cooling zone (19) is defined by area of the resistant band (40) outside the heating zone (17).

Die Erfindung betrifft eine Vorrichtung zum Siegeln einer, Näpfe (2) aufweisenden Formfolie (1) mit einer Deckfolie (3), mit einer mittels eines Walzenantriebes (4) antreibbaren, in ihrer Umfangsfläche Vertiefungen (6) für die Näpfe (2) aufweisenden Vorschubwalze (5) und einer darauf ablaufenden Siegelwalze (8), zwischen denen hindurch die Formfolie (1) und die Deckfolie (3) durchführbar sind. In der Vorschubwalze (5) ist eine Druckkammer (15) ausgebildet, die über eine Druckmittelleitung (16) mit einer Druckmittelquelle (17) verbunden ist, um über eine Änderung des Umfanges der Vorschubwalze (5) eine genaue Korrelation der Lage der Näpfe (2) und der Vertiefungen (6) zu erreichen.
摘要:
The device makes it possible to produce at least one scored line in at least one plastic outer layer of a film (10). It comprises a bearing surface for the film (10) and at least one projection (52a, 52b) for forming the scored line by penetration of the projection into the said plastic layer (12) when the film (10) is in position against the said bearing surface. The projections maybe arranged in the form of ribs on one or more coaxial rollers (51a, 51b). The projections may form the scored line by ultrasonic plastic flow, the film being compressed between a sonotrode and the rollers. The invention provides methods using these devices. It also provides films having scored lines, and packagings having scored lines.

The invention is a mounting system for a vibrational element. The vibrational element has a longitudinal axis, an outer surface and an axial displacement node. The mounting system includes an isolation member which has an isolation surface, an isolating body, and an engaging portion. The engaging portion is immovably secured to the isolation member and extends radially inward from the isolation body at a point radially opposite the isolation surface. The engaging portion is disposed so as to engage to the outer surface of the vibrational element. Radial displacements of the vibration element are substantially decoupled from the isolation surface through the engaging portion.

Eine Walzenvorrichtung (300) umfaßt eine Walze (10) mit einem zylindrischen, den arbeitenden Walzenumfang (2) bildenden Walzenkörper (1), der an den Enden drehbar gelagert ist, und mit dem Walzenkörper (1) zugeordneten, über die Länge des Walzenkörpers (1) sich erstreckenden und auf ihn wirkenden Temperiermitteln, die in einer Ausnehmung (6) des Walzenkörpers (1) angeordnet sind und mittels deren der Walzenkörper (1) bevorzugt in einem engen Umfangswinkelbereich um eine durch die Achse (A) des Walzenkörpers (1) gehende Ebene (E) herum temperierbar ist.
摘要:
A method for closing hermetically the housing (1) of a capacitor, particularly a capacitor provided with an overpressure device, the housing being composed of a cylindrical container (2) and a cover (3), both made of plastics, comprising the steps of : providing an annular shoulder (13) inside the container (2) at a distance from the edge of the container that is greater than the thickness of the peripheral region of the cover; placing the cover (3) inside the container (2) so that it rests on the annular shoulder (13), so that the edge of the container protrudes above the peripheral region of the cover with an annular portion; and bending, while applying heat, the annular portion over the peripheral region of the cover so as to provide a lip (15) that is adapted to retain hermetically the cover between the lip (15) and the shoulder (13).
