摘要:
A method of producing a package comprising: forming a hollow body having at least one vertex from sheet material; forming at least one join 413a, 413b by attaching together edges of the sheet material, the at least one join adjacent to the at least one vertex; and attaching the sheet material together in a region 415a adjacent the join and the vertex to form a grasping area; said forming the join and said attaching being carried out in a single operation by applying heat, applying pressure, or applying both heat and pressure, to the sheet material using seal jaws.

A packaging apparatus including a cutting device, the cutting device comprising an elongate holder (121), an elongate knife (112) having an elongate cutting edge, and a heat seal device, the heat seal device comprising a pair of elongate pressure strips (126, 128) located on the elongate holder on opposed sides of the knife (112) and projecting outwardly from the elongate holder (121), each pressure strip (126, 128) extending along a respective side of the knife (112), wherein each pressure strip (126, 128) comprises an elongate bar (126, 128) mounted for sliding movement in a respective slot (127, 129) in the elongate holder (121), the sliding movement varying the distance an outer edge (131) of the elongate bar projects from the elongate holder, and a biasing element (133, 135) within the respective slot, the biasing element engaging an inner edge (137, 139) of the elongate bar and arranged to bias the elongate bar (126, 128) outwardly of the slot. A packaging method is also disclosed.

Um mittels einer vertikalen Schlauchbeutelmaschine (1) Stapel (137) aufeinandergelegter Gegenstandsgruppen (23), insbesondere aus Kaffeepads in Schlauchbeutel (16) abpacken zu können, wird vorgeschlagen, ein Füllrohr (6) entweder an die horizontalen Abmessungen der Gegenstandsgruppen (23) anzupassen oder mit einem Einsatz (125) zu versehen, um den Stapel während seiner Fallbewegung im Füllrohr (6) zu stabilisieren. Der Einsatz (125) ist ebenso der Geometrie der Gegenstände angepasst, um diese während ihres Falls im Füllrohr (6) zu stabilisieren.
摘要:
An expandable plastic film gusseted bag in which each front panel gusset (64, 66) is connected to a rear panel gusset and each of the panel gussets is foldable between the front panel (63) and the rear panel to provide a continuous bag periphery. A bottom joins the bottom of the front panel, rear panel, two rear panel gussets and two front panel gussets at substantial right angles to the side edges of the front panel, rear panel, and gussets to close the bottom of the bag and leave only the top (62) open. The improvement provides the plastic bag with eight first linear folding axes adjacent the bottom. A linear folding axis is located within the front panel, each front panel gusset, the rear panel, and each rear panel gussets. Each folding axis extends from the joinder of a gusset at the bottom to a side edge of the front panel or the rear panel and the front panel gusset or the rear panel gusset at an approximate 45° angle. The folding axes are made by a process restricted to a group consisting of a cold seal and a hinge in the plastic film while the film is planar. On opening of the expandable gusseted bag, the bottom seal of the bag disposed adjacent the gussets forms a generally triangular shaped overlay relative to the gussets to form a flat bottom bag.
摘要:
Die Erfindung betrifft ein Verfahren zum kontinuierlichen Herstellen von Aufgußbeuteln, insbesondere für Tee, durch Ablegen einzelner Substanzquanten (3) auf einer Filterpapierbahn (2) und Bildung eines Schlauches sowie durch Ausbildung einzelner allseitig geschlossener, jeweils mindestens ein Substanzquantum (3) enthaltender Kammern (6), die an einem Trägermaterial (12) befestigt werden. Erfindungsgemäß werden die Kammern (6) durch eine Quernaht (9) gebildet, die zugleich die hintere Naht (9a) des einen und die vordere Naht (9b) des folgenden Aufgußbeutels und eine zwischen den beiden Nähten (9a und 9b) liegende Perforation (9c) umfaßt, an der die Aufgußbeutel im Verlauf des Verfahrens getrennt werden.
摘要:
Procédé et appareil de formation d'épissures diagonales dans une matière souple fusible (12, 16) et matière ainsi épissée. On forme l'épissure par chevauchement de la matière, tension (30, 32) de ladite matière au niveau de la zone à épisser, et par chauffage d'une bande de la matière sous tension jusqu'à sa température de fusion, ce qui permet de fusionner et de séparer (24) la matière au niveau de la bande. L'épissure (51) est presque indétectable à l'oeil non entraîné.
