Description
Nach dem Lochen eines Schriftstückes, Zeichnung, Urkunde, Plänen usw. (zwecks Einheftung in Ordner u. Schnellhefter) werden die Einheftlöcher zur Verstärkung mittels Lochverstärker beklebt. Es gibt daher schon etliche Lochverstärker, die jedoch für öfteres Ein- und Ausheften nicht so sehr geeignet sind, und meistens an der Lochung ausreißen. Um diesem Nachteil abzuhelfen habe ich einen auf einer Rolle gewickelten, an der perforierten Stelle abzureißende Lochverstärkerrolle entwickelt. Dieser aufzuklebende Lochverstärker besteht im Gegensatz zu anderen aus einer zäh-elastischen, durchsichtig und unlöslich selbstklebender Kunststoffolie, welche bereits gelocht ist. Auf der Kleberseite ist ein Öl- oder Wachspapierstreifen etc. wegen der hohen Klebefestigkeit, zum Abziehen von der Folie angebracht. Der von mir in kleinem Außenmaß entwickelte Lochverstärker (als Abreißfolie-Rolle fungierend) hält einer Zerreißprobe von immerhin 13,9 Kp stand, dann zerreißt das zu den Versuchen verwendete normale Schreibmaschinenpapier entzwei und nicht wie üblich, die Löcher.After punching a document, drawing, certificate, plans, etc. (for the purpose of being stapled in folders and loose-leaf binders), the holes are pasted for reinforcement using a hole reinforcement. There are therefore already a number of hole reinforcements, but they are not very suitable for frequent stitching in and out and usually tear at the holes. To remedy this disadvantage I have developed a hole reinforcement roll that is wound on a roll and tears off at the perforated point. This stick-on hole reinforcement, in contrast to others, consists of a tough, elastic, transparent and insoluble self-adhesive plastic film, which is already perforated. On the adhesive side there is an oil or wax paper strip, etc. because of the high adhesive strength, so that it can be peeled off the film. The hole reinforcement I developed with a small external dimension (acting as a tear-off foil roll) withstands a tensile test of at least 13.9 Kp, then the normal typewriter paper used for the tests tears in two and not the holes as usual.
