Title (DE) VERFAHREN ZUR HERSTELLUNG VON ABGEWINKELTEN HOHLPROFIL-LEISTEN
(EN) METHOD FOR PRODUCING BENT HOLLOW PROFILE STRIPS
(FR) PROCEDE DE PRODUCTION DE BARRES PROFILEES CREUSES COUDEES
Abstract:
(DE) Beim Verfahren zur Herstellung von abgebogenen Hohlprofil-Leisten aus Kunststoff wird beim Biegen beidseits der Biegestelle in den Hohlraum Kunststoff eingefüllt, um diesen Bereich zu verstärken. Dabei werden folgende Schritte durchgeführt: Einspannen einer Kunststoff-Leiste (1) in eine Biegevorrichtung; Erwärmen der Biegestelle; Biegen der Leiste, und Einbringen von Kunststoff (7) in den gebogenen Bereich beidseitig dieses Bereiches. Ein solches Verfahren erlaubt die Herstellung stabiler Kunststoff-Rahmen mit verstärkten Ecken zur Verwendung als Abstandhalter bei Mehrscheiben-Isolierverglasungen.
(EN) The invention relates to a method for producing plastic, bent, hollow profile strips. According to said method, the hollow section is filled with plastic on both sides of the bend point during bending, in order to reinforce this area. The process comprises the following steps: fixing a plastic strip (1) in a bending device; heating the bend point; bending the strip, and inserting plastic (7) into the bent area on both sides of this area. The invention hereby provides a means of producing stable plastic frames with reinforced corners for use as separators in multi-pane insulating glazing.
(FR) L'invention concerne un procédé de production de barres profilées creuses coudées en plastique, selon lequel du plastique est introduit, lors du pliage, dans la cavité, de part et d'autre du point de pliage, afin de renforcer cette zone. Ce procédé comporte les étapes suivantes: fixation d'une barre en plastique (1) dans un appareil à plier, chauffage du point de pliage, pliage de la barre et introduction de plastique (7) dans la zone coudée, de part et d'autre de cette zone. Un tel procédé permet de produire des cadres en plastique stables à angles renforcés, utilisés comme écarteurs dans les vitrages isolants à plusieurs vitres.
