Abstract

In order to connect fasteners, such as, for example, nails, screws, pins etc., to form strips or rolls, connecting belts made of plastic are used, the plastic being composed of two plastic components to obtain the desired properties. If the granules of these plastic components are mechanically mixed with one another prior to melting, the connecting belt then has the desired properties even at very high and very low temperatures.

Description

Es ist bekannt, Befestiger, wie z. B. Nägel, Schrauben, Stifte usw., durch Verbindungsgurte aus Kunststoff zu Streifen oder Rollen zur Verwendung in einem Eintreibgerät miteinander zu verbinden.It is known to use fasteners such. B. nails, screws, pins, etc., by connecting straps made of plastic to strips or rolls Use in a tacker to connect.

Als Kunststoffe dienen Polyäthylen, Polypropylen oder Co-Polymerisate aus Polyäthylen und Polypropylen.Polyethylene, polypropylene or copolymers are used as plastics made of polyethylene and polypropylene.

In der Praxis hat es sich gezeigt, daß solche Verbindungsgurte besonders bei Kälte eine hohe Spannungsrißempfindlichkeit aufweisen, was beim Bruch des Verbindungsgurtes zu unangenehmen Störungen beim Einschlag­ vorgang führt.In practice, it has been shown that such connecting straps are special have a high sensitivity to stress cracking in the cold, which is the case with Breaking of the connecting belt leads to unpleasant disturbances during the impact operation leads.

Dieselben Nachteile ergeben sich bei Polyäthylen, das bei sehr hohen Temperaturen zu weich wird und bei Polypropylen, das bei Kälte ver­ sprödet.The same disadvantages arise with polyethylene, that with very high ones Temperatures become too soft and with polypropylene, which ver brittle.

Aufgabe der vorliegenden Erfindung ist daher die Schaffung eines Verbindungsgurtes der eingangs genannten Art und eines Verfahrens zur Herstellung desselben, dessen Eigenschaften einen ungestörten Betrieb unter allen in der Praxis vorkommenden Bedingungen erlaubt.The object of the present invention is therefore to create a Connecting belt of the type mentioned and a method to produce the same, the properties of which are undisturbed Operation permitted under all conditions occurring in practice.

Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil der Ansprüche 1 und 2 angegebenen Merkmale gelöst.This object is achieved by the in the characterizing part of claims 1 and 2 specified features.

Das Granulat der Kunststoffe Polyäthylen und Polypropylen kann vor dem Einfüllen in einen Extruder in einem Mischgerät mechanisch mit­ einander vermischt werden. Im Extruder wird dieses Mischgranulat geschmolzen und als Verbindungsgurt auf die Schäfte der Befestiger aufgetragen. The granules of the plastics polyethylene and polypropylene can be used mechanically with the filling in an extruder in a mixer to be mixed up. This mixed granulate is in the extruder melted and used as a connecting strap on the shafts of the fasteners applied.  

In der Praxis hat es sich nun überraschenderweise gezeigt, daß dieser Verbindungsgurt alle Eigenschaften aufweist, die zum Verarbeiten des Befestigungsstreifens bei sehr hohen und sehr tiefen Temperaturen notwendig sind.In practice, it has now surprisingly been found that this connecting belt has all the properties required for Processing the fastening strip at very high and very high low temperatures are necessary.

Neben einer sehr guten Spannungsrißbeständigkeit weist der Verbindungsgurt gemäß Erfindung folgende Merkmale auf:In addition to very good stress crack resistance, the Connection belt according to the invention has the following features:

  • a) Kerbschlagzähigkeit nach DIN 53 453 bei minus 10°C, mind. 10.a) Notched impact strength according to DIN 53 453 at minus 10 ° C, at least 10.
  • b) Vicat-UST/B/50-Erweichungstemperatur nach DIN 53 460, mind. 70.b) Vicat-UST / B / 50 softening temperature according to DIN 53 460, at least 70.
  • c) Reißdehnung nach DIN 53 455 Geschw. VI, Prüfstab 3, mind. 500%.c) Elongation at break according to DIN 53 455 speed VI, test rod 3, at least 500%.
  • d) E-Modul nach ISO 178, mind. 1200.d) Modulus of elasticity according to ISO 178, at least 1200.

Beim erfindungsgemäßen Verfahren ergibt sich der Vorteil, daß beim mechanischen Mischen der Komponenten diese in beliebigen Verhältnissen gewählt werden können, um die günstigsten Eigen­ schaften je nach Anwendungsfall zu erhalten.The advantage of the method according to the invention is that when mechanically mixing the components in any Ratios can be chosen to be the cheapest own depending on the application.

Der Benutzer kann auch handelsübliche, überall erhältliche Mengen der gewünschten Kunststoffkomponenten erwerben, wogegen bei einer chemischen Mischung große Abnahmemengen und Wartezeiten notwendig sind.The user can also purchase commercially available, ubiquitous quantities acquire the desired plastic components, whereas at one chemical mix large purchase quantities and waiting times necessary are.
