    摘要: A process for making a container (10), comprising:
    cutting a folded web (50) of thermoplastic material in a direction transverse to a first direction of travel of the folded web into a plurality of container templates, each container template having a first opposing wall (12) and a second opposing wall (14), a seam (20) defined by a junction of the first opposing wall (12) and the second opposing wall (14), opposing first and second upper ends (13, 15) of the first and second walls (12, 14), respectfully, defined opposite the seam (20), and a first side (24) and a second side (26) defined between the seam (20) and the opposing first and second upper ends (13, 15);
    rotating each container template to orient the first side (24) and the second side (26) along a second direction of travel; and
    sealing one or both of the first side (24) and the second side (26).

    摘要: The purpose of the present invention is to reduce unwelded portions of a web and a strip-shaped member. This welding device includes: a pair of pressing members 3 for pressing a web 1 and a strip-shaped member 2; a feed device 4 for continuously or intermittently feeding the web 1 and the strip-shaped member 2 so as to pass between the pair of pressing members 3; and a laser device 5 for directing a laser beam 50 at the web 1 or the strip-shaped member 2 at a position upstream of the pair of pressing members 3. The welding device may comprise a movement device 6 that, while the feeding is stopped, moves the pair of pressing members 3 upstream of the web 1 and the strip-shaped member 2. Alternatively, the feeding device 4 may stop the web 1 and the strip-shaped member 2 after returning the web 1 and the strip-shaped member 2 by a given length.

    摘要: Vorgestellt wird eine Vorrichtung (15) und ein Verfahren zum Aufbringen von Deckblättern (9) auf Kreuzböden von Schlauchabschnitten (2) aus Kunststoffmaterial. Die Vorrichtung (15) umfasst Fördereinrichtungen (4, 20) zum Transport der Schlauchabschnitte (2) und zum Ablegen der Deckblätter (9) auf die Kreuzböden in einem Ablegebereich (23). Weiterhin umfasst die Vorrichtung (15) eine Heißgaseinrichtung (24) mit einem Gaserhitzer (30) und einer an den Gaserhitzer (30) angeschlossenen, zum Ablegebereich (23) für die Deckblätter (9) gerichteten Düse (32), wobei bei Zufuhr von Gas zum Gaserhitzer (30) das Gas entlang eines Strömungspfads (33) von der Gaszufuhr durch den Gaserhitzer (30) und die Düse (32) in den Ablegebereich (23) strömt. Die Heißgaseinrichtung (24) besitzt ein Heißgasreservoir (31) mit einem Innenvolumen (36) zum temporären Speichern von Heißgas, wobei der Strömungspfad (33) durch das Heißgasreservoir (31) verläuft. Ein Gas-Massenstrom an zum Gaserhitzer (30) zugeführten Gas ist mittels einer Steuerung (34) regelbar.
