Abstract

Beschrieben wird ein Verfahren zur Bearbeitung eines ein Trockenmittel enthaltenden Bandes (4a) aus Kunststoff im Verlauf der Herstellung eines rahmenförmigen Abstandhalters (4) für eine Isolierglasscheibe (1), mit folgenden Schritten: das Band wird auf seiner der Außenseite (6) abgewandten Seite, welche nachfolgend als seine Innenseite (5) bezeichnet wird, an zumindest einer für das Bilden einer Ecke des rahmenförmigen Abstandhalters (4) vorgesehenen Stelle mit einer Ausklinkung (14) versehen; eine dem Umfang der Isolierglasscheibe (1) angepasste Länge des Bandes (4a) wird von einem Vorrat des Bandes (4a) abgeschnitten. Erfindungsgemäß ist vorgesehen, dass beim Abschneiden des Bandes (4a) eine Schneide (28; 29) in einer solchen Richtung durch die Folie hindurch bewegt wird, dass die von der Schneide (28; 29) auf die Folie ausgeübte Kraft von der Außenseite (6) des Bandes (4a) aus schräg zur Außenseite (6) des Bandes (4a) in Richtung seiner Innenseite (5) gerichtet ist und die Schneide (28; 29) einen Schnitt erzeugt, der auf der Außenseite (6) des Bandes (4a) im rechten Winkel zu dessen Längsrichtung (13) fortschreitet.

Figure imgaf001
A process is described for processing a strip (4a) of plastic containing a desiccant in the course of producing a frame-shaped spacer (4) for an insulating glass pane (1), comprising the following steps: the strip is turned on its side facing away from the outside (6), which is hereinafter referred to as its inner side (5), provided with a notch (14) at at least one point provided for forming a corner of the frame-shaped spacer (4); a length of the strip (4a) adapted to the circumference of the insulating glass pane (1) is cut off from a supply of the strip (4a). According to the invention, when cutting off the strip (4a), a cutting edge (28; 29) is moved in such a direction through the film that the force exerted by the cutting edge (28; 29) on the film is prevented from the outside (6) ) of the belt (4a) is directed obliquely towards the outside (6) of the belt (4a) in the direction of its inside (5) and the blade (28; 29) produces a cut which is made on the outside (6) of the belt (4a ) at right angles to its longitudinal direction (13).
