Abstract

The belts are made of plastic, or plastic-coated fabric, and in particularly of glass-fibre coated with PTFE. One end of the belt is slit along the band-length, and the resultant laps are joined to the other end of the belt, with one lap uppermost and another under the end to be joined, and so on, in alternating succession. The laps are finally welded to the other end of the belt.

Description

Stoßverbindung für Endlosbänder Die vorliegende Erdindung bezieht sich auS ein flexibles Sadlosband, welches aus Kunststoff oder kunststoffbeschichtetem Gewebe, insbeaondere aus mit PTFE beschichtetem Glasgewebe besteht0 Derartige Bänder werden zum Beispiel in der Sußwaren- oder Lebensmittelindustrie eingesetzt und zwar da, wo unverpackte oder verpackte Waren mit Klebstoffresten an der Verpackung transportiert werden und das beförderte Gut am Transportband anhaften kann.Butt joint for endless belts The present earth connection relates consists of a flexible Sadlosband, which is made of plastic or plastic-coated Fabric, in particular made of glass fabric coated with PTFE, consists of such tapes are used, for example, in the confectionery or food industry wherever unpackaged or packaged goods with adhesive residues on the packaging are transported and the transported goods can adhere to the conveyor belt.

Die besagten Bänder werden weiterhin an Folienschweißmaschinen zur Abdeckung der Schweißbacken benutzt, um zu verhindern, daß die zu Sacken, Schläuchen oder dergleichen zu verschweißenden folien an den Schweißbacken anhaften. Die obigen Bänder werden also überall dort eingesetzt, wo Güter benutzt oder gefördert werden, die zum Anhaften neigen.The said tapes are still used on film sealing machines Cover of the welding jaws used to prevent the sagging, hoses or similar foils to be welded adhere to the welding jaws. The above Belts are used wherever goods are used or conveyed, that tend to cling.

Eine Schwierigkeit bei der Herstellung dieser Bänder betrifft die Verbindung der beiden freien Bandenden, um so ein Endlosband zu erzeugens Bisher war es üblich, die beiden freien Bandenden stumpf oder überlappt aneinander zu schweißen. Die Haltbarkeit stumpf geschweißter Bandenden läßt jedoch zu wünschen übrig0 Die Aufgabe der vorliegenden Erfindung besteht nun darin, die bisher übliche Verbindung der Bandenden zu verbessern.One difficulty in making these tapes relates to Connection of the two free ends of the belt in order to create an endless belt it was common practice to butt or overlap weld the two free ends of the tape to one another. The durability of butt welded However, tape ends leave something to be desired Remainder0 The object of the present invention is now the customary To improve the connection of the belt ends.

Dies geschieht bei einem Band aus Kunststoff oder kunststoffbeschichtetem Gewebe, insbesondere aus mit PTFE beschichtetem Glasgewebe, dessen freie Sonden zu einem Endlosband miteinwander verbunden sind dadurch, daß in wenigstens eines der vorzugsweise rechtwinkligen Bandenden im wesentlichen in Bandlängsrichtung verlaufende Schlitze eingestanzt und die dadurch geb iideten len am gegenüberliegenden Bandende wechselseitig oben und unten anliegend mit diesem v-erschweiXt werden.This happens with a tape made of plastic or plastic-coated Fabric, in particular made of glass fabric coated with PTFE, its free probes are connected with one another to form an endless belt in that at least one the preferably right-angled tape ends extending essentially in the longitudinal direction of the tape Punched slots and the resulting lines at the opposite end of the tape be welded alternately at the top and bottom with this.

Ein erfindungsgemäßes Ausführungsbeispiel ist in der beigefügten Zeichnung dargestellt.An exemplary embodiment according to the invention is shown in the accompanying drawing shown.

Darin zeigt: Fig. 1 zwei Bandenden, deren eines mit Längsschlitzen versehen ist, Fig. 2 die Bandenden gemäß Fig. 1 nach dem Ver-Schweißen miteinander, und Fig. 3 eine andere Verbindung, bei welcher beide Bandenden mit schrägen Schlitzen versehen sind.1 shows two tape ends, one with longitudinal slits Fig. 2 shows the strip ends according to Fig. 1 after being welded together, and FIG. 3 shows another connection in which both ends of the tape have inclined slits are provided.

Nach Fig. 1 sind in das Bandende 1 zweier miteinander zu verbindender, reohtwinklig geschnittener Bandenden, die mit 1 und 2 bezeichnet sind, Schlitze 3 eingestanzt0 Die Schlitze 3 verlaufen in Bandlängsrichtung und die dadurch gebildeten Lappen 4 sind abwechselnd nach oben und nach unten abgewinkelt.According to Fig. 1 are in the tape end 1 of two to be connected, cut at right angles Tape ends, denoted by 1 and 2 are punched, slots 3 The slots 3 run in the longitudinal direction of the tape and the tabs 4 thus formed are angled alternately upwards and downwards.

Fig. 2 veranschaulicht, in welcher Weise die Bandenden zusammengesteckt und miteinander verschweißt sind. Die Dicke der Oberlappung beträgt nach dem Verschweißen nicht mehr, als das Anderthalbfache der Bandstärke.Fig. 2 illustrates the manner in which the tape ends are plugged together and welded together. The thickness of the overlap is after welding no more than one and a half times the tape thickness.

Gemäß Fig. 3 verlaufen die Schlitze.3 leicht schräg zur Bandlängsrichtung derart, daß die dadurch gebildeten Lappen Schwalbenschwanzform besitzen. Außerdem sind die Schlitze in beiden Bandenden vorgesehene Selbstverständlich können auch bei in Bandlängsrichtung verlaufenden Schlitzen beide Bandenden geschlitzt sein.According to FIG. 3, the slots.3 run slightly obliquely to the longitudinal direction of the belt such that the lobes thereby formed have a dovetail shape. aside from that the slots are provided in both ends of the tape in the case of slits running in the longitudinal direction of the belt, both ends of the belt should be slotted.
