Abstract

An arrangement for laying out and tensioning flat workpieces (1), comprises a plastic film. The film reduces in length in at least one direction when it is heated and/or irradiated with UV light. The film (2) is self adhering.

Description

Flächige Materialien aus allen in der Technik eingesetzten Werkstoffen (Holz, Kunststoff, Metall, Glas, Verbundstoffe) neigen dazu, sich zu wölben, wenn chemische oder physikalische Einflüsse Vorder- und Rückseite dieser Flächen unterschiedlich beeinflussen. Dieses Phänomen ist größtenteils unerwünscht, es werden daher mechanische Ausrichtbeschläge verwendet, die - meist in die Fläche eingesetzt - die konvexe Fläche des Werkstückes spannen und so zur Begradigung des Flächenelements führen. Als Beispiel hierfür können Schrankschiebetüren herangezogen werden, die - oftmals hinter der Plattenebene - aufgehängt, zur Durchbiegung neigen und deshalb mit Ausrichtbeschlägen versehen werden.Flat materials from all used in technology Materials (wood, plastic, metal, glass, composite materials) tend to bulge when chemical or physical influences front and back of this Affect areas differently. This phenomenon is mostly undesirable, so it becomes mechanical Alignment fittings used, which - mostly in the area inserted - clamp the convex surface of the workpiece and thus lead to the straightening of the surface element. As An example of this is sliding cabinet doors are hung up, often behind the plate level, tend to bend and therefore with alignment fittings be provided.

In anderen Fällen - beispielsweise bei Bilderrückwänden - erweist sich eine Wölbung der Fläche als vorteilhaft, da ein Andruck der Bilderrückwand gegen Bild und Glas zunächst nur über Federn, die in den Rahmen des Bildes greifen, möglich ist. Um Druck auf die innere Fläche des Bildes auszuüben, werden daher mechanische Spanner eingesetzt, die die Rückwand nach vorn wölben sollen.In other cases - for example with picture back walls - a curvature of the surface proves to be advantageous since a First press the back wall against the picture and glass only about springs that reach into the frame of the picture, is possible. To print on the inner surface of the picture mechanical tensioners are used, which should arch the back wall forward.

In allen Fällen bedeutet die Anbringung der Ausrichtbeschläge - vor allem dann, wenn sie aus der Plattenebene nicht oder nur sehr wenig herausstehen dürfen und deshalb eingelassen werden müssen - großen Aufwand; sowohl was den Arbeitszeit- als auch den Materialaufwand betrifft.In all cases, the attachment of the Alignment fittings - especially if they come from the Do not protrude the plate level or only very little and therefore have to be admitted - great effort; both in terms of working time and material costs concerns.

Der im Patentanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, flächige Werkstoffe mit geringem Arbeits-- und Materialaufwand auszurichten.The invention specified in claim 1 is Underlying the problem, flat materials with little work-- and align material costs.

Dieses Problem wird durch die im Patentanspruch 1 aufgeführten Merkmale gelöst:This problem is solved by the in claim 1 listed features solved:

Durch Aufkleben der Kunststoff-Folie 2 auf die zu verkürzende Seite der auszurichtenden Platte 1 (ähnlich Klebeband) ist die Montagearbeit für einen Ausrichtbeschlag ersetzt - durch anschließende Erwärmung der Folie (Heißluftfön) wird die Platte ausgerichtet. By gluing the plastic film 2 onto the side of the plate 1 to be shortened (similar to adhesive tape), the assembly work for an alignment fitting is replaced - the plate is aligned by subsequent heating of the film (hot air dryer).

Weitere Ausführungsvarianten:Other versions:

Während sich die Molekülketten einiger Kunststoffe (zum Beispiel Polyolefine) unter Einwirkung von Wärme verkürzen, trifft dies für andere unter Einwirkung von UV-Licht zu. Analog zur oben stehenden Vorgehensweise werden Bänder aus diesen Materialien durch die Bestrahlung mit UV-Licht verkürzt.While the molecular chains of some plastics (e.g. Shorten polyolefins) when exposed to heat, this applies to others under the influence of UV light. Analogous to the procedure above, tapes from these materials by irradiation with UV light shortened.

Vorteilhaft auf den Wirkungsgrad des Mittels zeigte sich die partielle Verklebung 3 der Folienstreifen 2 (Fig. 2).The partial adhesion 3 of the film strips 2 ( FIG. 2) was found to be advantageous for the efficiency of the agent.

Anstelle der Verklebung der Folie können andere Halter (z. B. Klemmen), die auf dem Werkstück konventionell befestigt werden, zum Einsatz kommen.Instead of gluing the film, other holders (e.g. Clamps), which are conventionally attached to the workpiece will be used.
