Description

Vorrichtung zum Befestigen von Zeichenunterlagen mittels Selbstklebestreifen Die Erfindung verbessert die Halterung der Zeichenunterlage aus Polyvinylchlorid auf der Reißbrettflächemit zwischengelegten doppelseitigen Selbstklebestreifen nach Patent 1007 212.Device for attaching drawing supports by means of self-adhesive strips The invention improves the holding of the drawing support made of polyvinyl chloride on the drawing board surface with double-sided self-adhesive strips according to patent 1007 212 inserted between them.

Das wesentliche Merkmal der Zusatzerfindung besteht in der Verwendung eines doppelseitigen Selbstklebestreifens, der in der Längsrichtung an seinen freien Enden versetzt mit einer in an sich bekannten Weise die ganze Breite des Streifens erfassenden Klebschicht versehen ist, derart, daß zwischen den Klebschichten auf dem Streifen eine über die ganze Breite des Streifens laufende zweiseitige klebstoffreie Streifenstelle ist.The essential feature of the additional invention is the use of a double-sided self-adhesive strip, which is in the longitudinal direction on its free Ends offset in a manner known per se the entire width of the strip detecting adhesive layer is provided in such a way that between the adhesive layers on the strip a two-sided adhesive-free running over the entire width of the strip Strip spot is.

Bekannt ist ein, Selbstklebestreifen mit kleb urfreier Mittelzone, neben der sich die Klebschichten befinden, während die Rückseite des Streifens kleberfrei ist. Für den Erfindungszweck ist solcher Streifen untauglich.A self-adhesive strip with a tack-free central zone is known, next to which the adhesive layers are, while the back of the strip is adhesive-free is. Such a strip is unsuitable for the purpose of the invention.

Die Befestigung der PVC-Zeichenunterlage auf dem Reißbrett verursacht keine Nachteile, wenn das Zeichengerät in gleichmäßig temperiertem Raum untergebracht ist. Dann dürfen die doppelseitigen Klebstreifen dem Hauptpatent gemäß zwischen Brett und PVC-Unterlage liegen. Bei starken Temperaturschwankungen aber können wegen verschiedener Ausdehnung des Brettes und der PVC-Tafel Verwerfungen in Form von Wellen in der Tafel oder von Wölbung im Brett entstehen.The attachment of the PVC drawing pad to the drawing board caused no disadvantages if the drawing device is housed in a room with a uniform temperature is. Then the double-sided adhesive strips may according to the main patent between Board and PVC underlay lie. In the event of strong temperature fluctuations, however, different expansions of the board and the PVC panel warps in the form of Waves in the board or from curvature in the board arise.

Die Gefahren durch Dehnungsunterschiede können dadurch vermieden werden, daß die PVC-Unterlage mit ihrer Rückseite nicht auf die Vorderseite des Reißbrettes geklebt, sondern über die breiten Brettkanten hinweg an der Rückseite des Brettes aufgehängt wird. Die beiden Klebflächen kommen dadurch um mehrere Zentimeter auseinander zu liegen, derart, daß sie sich für den Dehnungsausgleich gegeneinander verschieben können. Den Zusammenhang wahrt der auf der Brettkante lose liegende beidseitig kleberfreie Streifenteil.The dangers of expansion differences can be avoided by that the back of the PVC underlay does not touch the front of the drawing board glued, but across the wide board edges on the back of the board is hung. As a result, the two adhesive surfaces come apart by several centimeters to lie in such a way that they move against each other for expansion compensation can. The adhesive-free layer on both sides of the board maintains the connection Strip part.

Es ist nicht erforderlich, den Aufhängestreifen so breit wie die Zeichenunterlage zu halten. Es genügen über die Brettbreite zweckgerecht verteilte Schmalstreifen.It is not necessary to make the hanging strip as wide as the drawing pad to keep. Purposefully distributed narrow strips across the board width are sufficient.

Der Klebestreifen, der unter der Zeichenunterlage teilweise versteckt ist, ist an der Brettrückseite leicht nachspannbar.The adhesive strip that is partially hidden under the drawing pad can be easily tightened on the back of the board.

Wichtig ist die Widerstandsfähigkeit des Klebstoffträgers gegen Zug. Bewährt hat sich ein Werkstoff, bei dem in Selbstklebeleim eingebettete Kunststoffäden nebeneinander liegen. Ausreichend unelastisch und dehnungsfest bei sehr geringer Materialstärke (0,05 mm) ist Polyterephthalat.The resistance of the adhesive carrier to tension is important. A material has proven itself in which plastic threads embedded in self-adhesive glue lying next to each other. Sufficiently inelastic and resistant to stretching with very little Material thickness (0.05 mm) is polyterephthalate.

Die Vorrichtung ist aus einseitig beschichtetem Selbstklebeband herstellbar. Dazu werden zwei Bandstücke mit einander zugekehrten Klebflächen in der Breite der Reißbrettkante überlappt. Wirtschaftlicher ist die versetzte beidseitige Beschichtung mit freibleibender Mittelzone eines einzigen entsprechend breiten Bandes.The device can be produced from self-adhesive tape coated on one side. For this purpose, two pieces of tape with facing adhesive surfaces in the width of the The edge of the drawing board overlaps. The offset coating on both sides is more economical with a free central zone of a single, correspondingly wide band.
