Derartige Vorrichtungen befinden sich in verschiedenen Ausführungsformen auf dem Markte und haben sich im allgemeinen für den erwähnten Verwendungszweck, d.h. insbesondere die Herstellung endloser Kunststofftreibriemen, gut bewährt. Sämtlichen bekannten Konstruktionen dieser Art haftet jedoch der Nachteil an, dass die Belastung der Verbindungsfläche der beiden Bandabschnitte auf rein mechanischem Wege, beispielsweise durch Stahlfedern, Spindeln oder Kniehebel, erfolgt und ' dadurch zwangsläufig ungleichmässig ist. Ferner lassen diese mechanisch betätigten Pressvorrichtungen lediglich die Anwendung eines sehr begrenzten Druckes zu, was für zahlreiche Fälle nicht ausreicht. Die bekannten Konstruktionen haben ferner den Nachteil, dass die Presskraft nur an einem Punkt angreift, was eine Deformation der Pressplatten zur Folge hat und sich ungünstig auf das Pressgut auswirkt.Such devices are in various embodiments on the market and have in general for the mentioned purpose, i.e. in particular the production of endless plastic drive belts, well proven. All known constructions However, this type has the disadvantage that the load on the connecting surface of the two band sections takes place in a purely mechanical way, for example by means of steel springs, spindles or toggle levers, and 'is inevitably uneven as a result. Furthermore, these mechanically operated pressing devices only allow the application of a very limited pressure, which is insufficient for many cases. The known constructions furthermore have the disadvantage that the pressing force only acts at one point, which causes deformation of the pressing plates and has an unfavorable effect on the material to be pressed.

Dank der vorliegenden Erfindung werden diese Nachteile dadurch behoben, dass eine der beiden Metallplatten ortsfest.montiert und die zweite Metallplatte bezüglich ihres Abstandes von der erstgenannten Metallplatte beweglich gelagert ist, wobei an der der erstgenannten Metallplatte gegenüberliegenden Seite der zweiten Metallplatte ein Balg angeordnet ist, der mittels eines pneumatischen oder hydraulischen Mediums gefüllt werden kann und dann die beiden Metallplatten in ihrer Ar.belts'steilung mit einem einstellbarenThanks to the present invention, these disadvantages are eliminated in that one of the two metal plates ortsfest.montiert and the second metal plate with regard to its distance from the first-mentioned metal plate is movably mounted, on the opposite side of the first-mentioned metal plate of the second metal plate, a bellows is arranged, which means a pneumatic or hydraulic medium can be filled and then the two metal plates in their work division with an adjustable

gleichmässigen Druck gegen die zu verbindenden Endabschnitte des Materialstreifens presst.presses even pressure against the end sections of the material strip to be connected.

Bei dieser Anordnung kann die Presskraft über das pneumatische bzw. hydraulische Medium beliebig gewählt werden und es ist ausserdem gewährleistet, dass sich die Presskraft auf alle Teile der dem Balg benachbarten Metallplatte gleichmässig überträgt, so dass auch die Verbindungsfläche der beiden Endabschnitte des Ma-• terialstreifens gleichmässig belastet wird.With this arrangement, the pressing force can be selected as desired via the pneumatic or hydraulic medium and it is also guaranteed that the pressing force is applied to all parts of the bellows adjacent Metal plate transfers evenly, so that the connecting surface of the two end sections of the material strip is evenly loaded.

Eine bevorzugte Ausführungsform dieser Vorrichtung kennzeichnet sich dadurch, dass die erstgenannte Metallplatte in einem unteren Rahmen montiert, die zweite Metallplatte in einem kastenförmigen, einseitig offenen Gehäuse elastisch verschiebbar aufgehängt, das Gehäuse an dem genannten Rahmen schwenkbar angelenktA preferred embodiment of this device is characterized in that the first-mentioned metal plate is mounted in a lower frame, the second metal plate suspended elastically displaceably in a box-shaped housing open on one side, the Housing hinged to said frame

und der genannte Balg zwischen der zweiten Metallplatte und dem Boden des genannten Gehäuses angeordnet ist. Die Aufhängung des Gehäuses an der zweiten Metallplatte erfolgt zweckrnässigerweise mittels mindestens zweier am Gehäuse befestigter Metallstifte, die in entsprechende, an den Längsseiten der Metallplatte angeordnete Schlitze hineinragen, deren Höhe den Durchmesser der Metallstifte übersteigt.and said bellows is disposed between the second metal plate and the bottom of said housing. The suspension of the housing on the second metal plate is expediently carried out by means of at least two metal pins attached to the housing, which are inserted into corresponding ones on the long sides of the metal plate arranged slots protrude, the height of which exceeds the diameter of the metal pins.

Die in Fig. 1 dargestellte Vorrichtung weist einen Rahmen 1 auf, der mittels einer Schwenkachse 2 mit einem kastenförmigen Gehäuse "5 verbunden ist. Eine untere Heizplatte 4 ist am Oberteil des Rahmens 1 starr befestigt. Sie kann am Rahmen 1 entweder angeschraubt oder mit diesem verschwelsst oder auf andere, herkömmliche Weise mit dem Rahmen verbunden sein. An zwei einander gegenüberliegenden Randpartien der Platte 4 sind Spannschienen [5 und 6 angeordnet, welche mittels Schrauben 7 und 8 in der Heizplatte 4 verankert sind und zum Einspannen der beiden Endabschnitte 9a und 9b eines in seiner Gesamtheit mit 9 bezeichneten Transmissionsriemens dienen. Wie Insbesondere Fig. 4 zeigt, sind die einander überlappenden Endabschnitte 9a und 9b des Transmissionsriemens 9 unter einem relativ spitzen Winkel abgeschrägt und werden in ihrer Ueberlappungslage durch die Spannschienen 5 und β gehalten.The device shown in FIG. 1 has a frame 1 which is connected by means of a pivot axis 2 to a box-shaped housing 5. A lower heating plate 4 is rigidly attached to the upper part of the frame 1. It can either be screwed to the frame 1 or with it At two opposite edge parts of the plate 4, tensioning rails 5 and 6 are arranged which are anchored in the heating plate 4 by means of screws 7 and 8 and for clamping the two end sections 9a and 9b a power transmission belt designated in its entirety with 9 serve. As particular, Fig. 4, the overlapping end portions 9 are bevelled of the transmission belt at a relatively acute angle 9a and 9b and are held β un d in their Ueberlappungslage by the clamping rails 5.

zugewandte offene Seite zur Aufnahme einer oberen Heizplatte 10 dient.facing open side to accommodate an upper heating plate 10 serves.

Wie die Sohnittdarstellung nach Fig. 3 zeigt, weist die obere Heizplatte 10 an ihren beiden Längsselten je einen Längsschlitz lla/llb auf, in welchen jeweils ein von aussen in die Gehäusewandung eingeschraubter Gewindestift 12a/12b hineinragt. Da die Höhe der Schlitze lla/llb grosser ist, als der Durchmesser der Gewinde-' stifte 12a/12b, ist die Heizplatte 10 somit innerhalb des Gehäuses in Richtung des in Fig. 3 mit 13 bezeichneten Doppelpfeiles verschiebbar. Vorzugsweise werden an jeder Plattenseite, wie Fig. 1 zeigt, zwei Gewindestifte angeordnet. Beim Schliessen der Vorrichtung nach dem Einlegen der zu verbindenden Bandenden befinden sich die inneren Abschnitte der Gewindestifte 12a/l2b im unteren Bereich der reichlich bemessenen Schlitze lla/llb, so dass die Heizplatte 10 beim Oeffnen der Druckluftzufuhr zum Balg 16 nach unten gepresst werden kann.As the child representation of Fig. 3 shows, the upper heating plate 10 has a longitudinal slot 11a / 11b on each of its two longitudinal sides, in each of which a threaded pin 12a / 12b screwed into the housing wall from the outside protrudes. As the height of the slots lla / llb is larger than the diameter of the thread- ' pins 12a / 12b, the heating plate 10 is thus inside the housing in the direction of the designated 13 in FIG The double arrow can be moved. Preferably, as shown in FIG. 1, there are two threaded pins on each side of the plate arranged. When closing the device after inserting the tape ends to be connected are the inner sections of the threaded pins 12a / l2b in the lower area of the amply dimensioned slots lla / llb, so that the heating plate 10 can be pressed down when the compressed air supply to the bellows 16 is opened.

In jeder Heizplatte 4 bzw. 10 ist mindestens ein Heizkörper angeordnet, welcher als bekannt vorausgesetzt werden darf und daher der Uebersichtlichkeit halber nicht dargestellt ist. Die Heizkörper können über Anschlüsse 14 und 15 an ein elektrisches Netz angeschlossen werden. Auch auf die Darstellung der zur Steuerung des Heizvorganges erforderlichen Schalter und Thermostate wurde der Einfachheit halber verzichtet.In each heating plate 4 or 10, at least one heating element is arranged, which is assumed to be known may be and therefore for the sake of clarity is not shown. The radiators can be connected to an electrical network via connections 14 and 15 will. Also on the representation of the switches and thermostats required to control the heating process was omitted for the sake of simplicity.

zwischen der Heizplatte 10 und dem Oehäuseboden, ein Balg 3,6 angeordnet, der sieh über den gesamten Quersohnitt der Heizplatte 10 erstreckt. Dieser gasdichte Balg kann über eine Leitung 17 und ein Ventil 18 mit einer Druokluftquelle, beispielsweise einem Druckluftbehälter,, in Verbindung gebracht werden.between the heating plate 10 and the housing bottom Bellows 3,6 arranged, which look over the entire cross-son the heating plate 10 extends. This gas-tight bellows can via a line 17 and a valve 18 with a source of compressed air, for example a compressed air tank.

Das Gehäuse 3 weist an seiner Frontseite eine V Arretierklaue 19 auf, welche mit einem Griff 20 versehen und um eine Achse 21 schwenkbar gelagert ist. In der in Flg. 2 gezeigten geschlossenen Stellung der Vorrichtung untergreift die Klaue 19 eine am Vorderteil des Rahmens 1 befestigte Arretierschiene 22, so dass der Arretierzahn 19a der Klaue 19 in die unterhalb der Arretierschiene 22 befindliche Ausnehmung 23 hineinragt. Die Arretierklaue ist mittels einer nicht dargestellten Feder belastet, welche ständig danach trachtet, die Klaue in ihrer in Fig. 2 gezeigten Schliessstellung zu halten. Bewegt man dagegen den Griff 20 in Richtung des Pfeiles 24, dann löst sich die Arretierklaue 19 von der Arretierschiene 22 und das Gehäuse 3 lässt sich " um die Achse 2 verschwenken und damit vom Rahmen 1 abheben. The housing 3 has a V locking claw 19 on its front side, which is provided with a handle 20 and is mounted pivotably about an axis 21. In the in Flg. 2 shown closed position of the device the claw 19 engages under a locking rail 22 attached to the front part of the frame 1, so that the locking tooth 19a of the claw 19 protrudes into the recess 23 located below the locking rail 22. the Locking pawl is loaded by means of a spring, not shown, which constantly seeks the To hold the claw in its closed position shown in FIG. On the other hand, if you move the handle 20 in the direction of arrow 24, then the locking claw 19 is released from the locking rail 22 and the housing 3 can be "pivot about axis 2 and thus lift off frame 1.

Das beschriebene Ausführungsbeispiel lässt sich vom Fachmann in mannigfacher Weise abwandeln, ohne dass dadurch der im Patentanspruch umrissene Rahmen überschritten würde. So ist es beispielsweise ohne weiteres möglich, die elastisch verschiebbare Heizplatte 10 innerhalb des festen Rahmens 1 und die ortsfeste Heizplatte 4 am schwenkbaren Gehäuse 3 anzubringen. Auch die Befestigung der beiden Riemenab-The embodiment described can be modified in many ways by the person skilled in the art, without thereby exceeding the scope outlined in the patent claim.
