Description

Aktenhülle aus Kunststoffolie mit Randschweißnaht.File cover made of plastic film with edge weld seam.

Bei Aktenhüllen aus Kunststoffolie, deren Grund-und Deckblattrand an Rücken und Boden der Hülle durch eine Schweißnaht verbunden sind, beobachtet man den Mangel, daß die Schweißnahtenden bei längerer Spreizbeanspruchung aufreißen.For file covers made of plastic film, their base and cover edge are connected by a weld seam on the back and bottom of the shell one the defect that the weld ends tear open with prolonged spreading stress.

Durch die Neuerung wird hier Abhilfe geschaffen, indem die am äußeren Hüllenrande glatte Schweißnaht nach innen zu Vorsprünge aufweist, zwischen denen Luftkissen eingebettet sind. Durch diese Schweißnahtgestaltung wird ihre durch die Spreizung beanspruchte innere Schweißkante um ein Mehrfaches verlängert. Es ergibt sich eine hohe Reißfestigkeit des Hüllenrandes ; gleichzeitig wird dieser aber auch trotz einer verhältnismäßig breiten Gestaltung der Schweißnaht t biegsam gehalten. Die unverschweißten Luftkissen zwischen den Schweißvorsprüngen wirken wie eine Reihe elastischer Glieder, so daß als Hüllenstoff auch steifere und stärkere Folie als bisher herangezogen werden kann.The innovation provides a remedy here in that the weld seam, which is smooth on the outer edge of the envelope, has projections inward, between which air cushions are embedded. This weld seam design extends its inner weld edge, which is stressed by the expansion, many times over. The envelope edge has a high tear strength; but at the same time this will also be despite a relatively wide design of the weld seam t held flexible. The unwelded air cushions between the welding projections act like a series of elastic Links, so that stiffer and stronger film than before can be used as the cover material.

Die peißfestigteit der Schweißnahtenden wird noch erhöht, wenn das entlang des Einfügeschlitzes gegenüber dem Grundblatt etwas zurückversetzte Hüllendeckblatt bogenförmig nach außen zum Schweißnahtende ausmündet. Die Scherwirkung des einzufügenden papiers wird durch diese Anordnung wesentlich herabgesetzt.The piss strength of the weld ends is increased if that cover sheet slightly set back along the insertion slot compared to the base sheet opens out in an arc shape to the end of the weld seam. The shear of the insert paper is significantly reduced by this arrangement.
