 EMI1.1 
 zwei Schichten von Kunststoffolie, die durch Faltung aus demselben Stück gebildet sind und von denen die eine für die Befestigung, z. B. Festkleben, an einem Albumblatt   od. dgl.   bestimmt ist. 



   Versuche haben ergeben, dass eine durch Faltung einer Kunststoffolie von passender Dicke und aus geeignetem Material,   z. B. 0, 12 mm PVC-Mischpolymerisat   erhaltene Einstecktasche auf Grund ihrer elektrostatischen Eigenschaften im Stande ist, sich an einer eingelegten Briefmarke so festzusaugen, dass diese allein hiedurch sicher festgehalten wird. Eine absolute Bedingung   für'die Erzielung   dieser Wirkung besteht aber darin, dass die zwei Folienschichten über deren ganze Fläche ganz dicht ohne Luftspalt aneinander liegen. 



   Den Gegenstand der Erfindung bildet ein Gerät zur Herstellung solcher Einstecktaschen aus zwei Schichten thermoplastischer Kunststoffolie durch Faltung eines Folienstückes. Das Gerät besitzt in bekannter Weise zwei stationäre, um parallele Achsen drehbar gelagerte Rollen, von denen mindestens eine geheizt ist, wobei das Neue darin besteht, dass die Umfangsfläche der geheizten Rolle schwach konisch, die andere dagegen zylindrisch ausgebildet ist. Bei Anwendung dieses Gerätes verbleibt überhaupt kein Luftspalt an der Faltkante und können somit Einstecktaschen mit hervorragendem Festhaltevermögen in einfacher und billigster Weise hergestellt werden. Das Festhaltevermögen ist so gut, dass es möglich ist, die Einstecktaschen frei schwenkbar aufzukleben, so dass beide Seiten der Briefmarke wahlweise beobachtet werden können. 



   Die Erfindung wird nachstehend unter Hinweis auf die Zeichnung näher erläutert, die schematisch eine Seitenansicht eines Gerätes gemäss der Erfindung darstellt. 



   Eine schwach konische, geheizte   Metal1rolle --1-- ist   fest auf einer angetriebenen Welle-2-angeordnet. Eine darunter liegende   Rolle-3-aus   wärmeisolierendem Fibermaterial ist auf einer Welle - frei drehbar gelagert. 



   Ein Folienstreifen-5--, z. B. eine 0, 12 mm starke PVC-Mischpolymerisat-Folie, erhält beim Durchgang zwischen den beiden   Rollen--1   und   3-eine scharfe Falte-6-,   da das Material durch die Wärmezufuhr teilweise verschmolzen oder jedenfalls erweicht wird. Dadurch kommen die beiden Folienschichten so dicht aneinander zu liegen, dass sie sich gegenseitig oder bzw. und eine eingelegte Briefmarke ansaugen, wenn ein Folienmaterial mit entsprechenden elektrostatischen Eigenschaften ausgewählt wurde. 



   Die geheizte Rolle weist   z. B.   eine Temperatur in der Grössenordnung von 1200C auf, falls mit einer Folie von   0,   12 mm Dicke und mit passender Vorschubgeschwindigkeit gearbeitet wird. Die Folie kann aus   PVC-Mischpolymerisat   bestehen, wobei die gewünschten elektrostatischen Eigenschaften erreicht werden.

 EMI1.1
 two layers of plastic film formed by folding from the same piece, one of which is used for attachment, e.g. B. sticking, od on an album sheet. Like. Is determined.



   Tests have shown that by folding a plastic film of suitable thickness and made of suitable material, e.g. B. 0.12 mm PVC copolymer obtained insert pocket due to its electrostatic properties is able to suck on an inserted postage stamp so that it is securely held by this alone. However, an absolute condition for achieving this effect is that the two film layers lie very close to one another over their entire surface without an air gap.



   The subject matter of the invention is a device for producing such pockets from two layers of thermoplastic plastic film by folding a piece of film. The device has in a known manner two stationary rollers rotatably mounted about parallel axes, of which at least one is heated, the novelty being that the peripheral surface of the heated roller is slightly conical, while the other is cylindrical. When using this device, there is absolutely no air gap left on the folding edge and thus insert pockets with excellent retention properties can be produced in a simple and inexpensive manner. The retention is so good that it is possible to glue the insert pockets so that they can be swiveled freely so that both sides of the stamp can be observed as desired.



   The invention is explained in more detail below with reference to the drawing, which schematically shows a side view of a device according to the invention.



   A slightly conical, heated metal roller --1-- is fixed on a driven shaft-2-. An underlying roll-3-made of heat-insulating fiber material is mounted on a shaft so that it can rotate freely.



   A film strip-5--, e.g. B. a 0.12 mm thick PVC copolymer film, when passing between the two rollers - 1 and 3 - a sharp fold-6-, because the material is partially melted or at least softened by the heat. As a result, the two film layers come to lie so close to one another that they suck one another or or and an inserted postage stamp if a film material with corresponding electrostatic properties has been selected.



   The heated roller has e.g. B. a temperature of the order of magnitude of 1200C, if you are working with a film with a thickness of 0.12 mm and a suitable feed rate. The film can consist of a PVC copolymer, the desired electrostatic properties being achieved.
