Abstract

Laminated plate consists of a polyolefin layer and a cover layer of magnetic materials, bonded by an adhesive layer. It is used for registering terms, as board for reading purposes and an aid for constructional designs. The magnetic layer holds signs of suitable material. The plastic layer is more resistant to moisture and other influences than wood. Large plates can be easily produced.

Description

Verbundpl rotte Die Erfindung bezieht sich auf eine Verbundplatte mit einer Polyolefinschicht und mit mindestens einer Deckschicht, die mittels einer Klebeschicht miteinander verbunden sind.Composite panel The invention relates to a composite panel with a polyolefin layer and with at least one cover layer, which by means of a Adhesive layer are connected to each other.

Gegenstand des Patentes .... (Patentanmeldung P 21 48 176.5) der Anmelderin ist eine fUr Termintafeln und ähnliche Organisationsbehelfe sowie fUr didaktische und andere Darstellungszwecke geeignete Verbundplatte, bei der mindestens eine Deckschicht aus einem magnetisch wirksamen Werkstoff besteht, so daß auf der magnetischen Deckschicht mittels Magneten Zeichnungen, Bilder, selbst magnetische Signaturen, Symbole und dgl. Figuren angebracht werden können, die öfters geändert, verschoben oder ausgewechselt werden müssen. Subject of the patent .... (patent application P 21 48 176.5) of The registrant is for appointment boards and similar organizational aids as well as for composite panel suitable for didactic and other display purposes, with at least a cover layer consists of a magnetically effective material, so that on the magnetic cover layer by means of magnets drawings, pictures, even magnetic ones Signatures, symbols and the like. Figures can be attached, which are often changed, need to be moved or replaced.

Oft genügen aber solche Darstellunsmöglichkeiten allein nicht, sondern die Signaturen müssen z. B. bei der Darstellung von Schaltschemata, durch zeichnerische Mittel und Beschriftungen ergänzt werden. Die zeichnerischen Darstellungen mUssen jedoch ebenso leicht und schnell geändert werden können, wie die magnetisch-haftenden Signaturen. Often, however, such possibilities of representation are not enough, they are the signatures must e.g. B. in the representation of circuit diagrams, through graphic Means and labels are added. The graphic representations must however, they can be changed just as easily and quickly as the magnetically adhering ones Signatures.

Es ist also notwendig, daß die die magnetische Deckschicht trogende Seite der Verbundplatte beschriftet werden kann, und doB diese Darstellungen leicht entfemt d.h. weggewischt werden können.It is therefore necessary that the magnetic cover layer defy Side of the composite panel can be labeled, and doB these representations easily removed i.e. wiped away.

Die Verbundplatte gemäß der Erfindung ermöglicht dies. Sie ist dadurch geZ kennzeichnet, daß die magnetische Deckschicht mit einer beschrift- und abwaschbaren Kunststoff-Folie Uberzogen ist.The composite panel according to the invention makes this possible. She is through it geZ indicates that the magnetic cover layer with a writable and washable Plastic film is covered.

Die Kunststoff-Folie ist vorzugsweise eine Polyvinylchlorid (PVC)-Folie, die höchstens 200 µm dick sein soll, damit die Wirkung der magnetischen Deckschicht nicht beeintrachtigt wird.The plastic film is preferably a polyvinyl chloride (PVC) film, which should be at most 200 µm thick, so that the effect of the magnetic cover layer is not affected.

Die beiliegende Zeichnung zeigt im Sinne eines Beispiels eine aus der erfindungsgemößen Verbundplatte hergestellte Tafel im Querschnitt.The accompanying drawing shows an example as an example the panel made of the composite panel according to the invention in cross section.

Die Tafel umfaßt die Polyolefinschicht 1 als Kern und die magnetische Deckschicht 2. Es kann notwendig oder wünschenswert sein, auch die andere Seite der Polyolefinschicht mit einer Deckschicht 3 zu versehen. Diese kann auch magnetisch sein damit die Tafel beidseitig verwendbar ist. Die magnetische Deckschicht 2 ist mit einer beschrift- und abwaschbaren PVC-Folie4überzogen, auf welcher Signaturen magnetisch haften können.The board comprises the polyolefin layer 1 as a core and the magnetic one Top layer 2. It may be necessary or desirable to use the other side as well to provide the polyolefin layer with a cover layer 3. This can also be magnetic so that the board can be used on both sides. The magnetic cover layer 2 is Covered with a writable and washable PVC film4, on which signatures can adhere magnetically.

Zum Zeichnen und Beschriften können die üblichen Mittel verwendet werden.The usual means can be used for drawing and labeling will.

Die Beschriftungen können normalerweise mit Wasser entfernt werden. Bei Beschriftung mit Filzstiften kann es in hartnäckigen Fällen nötig sein, ein Aethanol-Wasser-Gemisch (1:1), Aethanol vergällt oder Spiritus zu verwenden.The writing can usually be removed with water. When writing with felt-tip pens, it may be necessary in stubborn cases to enter a Ethanol-water mixture (1: 1), denatured ethanol or spirit should be used.

Die erfindungsgemäße Verbundplatte ist besonders geeignet fUr Plongalerien, Wand- und Schultafeln, Termin-, Produktions- und Auftragsübersichten, zum Anbringen von Schoubildern, fUr Flip-Chart-Systeme und dgl.The composite panel according to the invention is particularly suitable for plong galleries, Wall and school boards, schedule, production and order overviews to attach of pictures, for flip-chart systems and the like.
