Vorrichtung zum Herstellen &ugr;&ogr;&pgr; Verbindungsnähten zwischen sich überlappenden TeilenDevice for producing &ugr;&ogr;&pgr; connecting seams between overlapping parts

Die Erfindung betrifft eine Vorrichtung zum Herstellen &ugr;&ogr;&pgr; Verbindungsnähten zwischen sich überlappenden Teilen aus elastomerem oder thermoplastischem Werkstoff, insbesondere bei Dach- oder Dichtungsbahnen, wobei die zu verbindenden Teile im Bereich der herzustellenden Naht erhitzt und zwischen zwei miteinander vorzugsweise nicht mechanisch verbundenen Vorrichtungsteilen eingespannt werden, und im Bereich eines der Vorrichtungsteile ein Heizlineal und im Bereich des anderen Teils ein Widerlager vorgesehen ist.The invention relates to a device for producing μγια connecting seams between overlapping parts made of elastomer or thermoplastic material, in particular in roofing or sealing membranes, whereby the parts to be connected are heated in the area of the seam to be produced and clamped between two device parts that are preferably not mechanically connected to one another, and a heating ruler is provided in the area of one of the device parts and an abutment is provided in the area of the other part.

Eine derartige Vorrichtung ist bereits der DE - OS 34 27 215 als bekannt zu entnehmen« Es ist jedoch technisch aufwendig, über die dort vorgesehenen Vakuumkammern den zur Herstellung einwandfreier Nähte erforderlich hohen DruckSuch a device is already known from DE - OS 34 27 215. However, it is technically complex to use the vacuum chambers provided there to generate the high pressure required to produce perfect seams.

Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, eine solche Vorrichtung derart ueiterzuentuickeln, daß sie bei einfachem Aufbau und großer Zuverlässigkeit im Betrieb die Herstellung einwandfreier Nähte sicherstellt.The present invention was therefore based on the task of developing such a device in such a way that it ensures the production of perfect seams with a simple structure and great reliability in operation.

Diese Aufgabe kann bei einer gattungsgemäßen l/orrichtung erfindungsgemäß dadurch gelöst uüidaß die Vorrichtung als erstes Teil mindestens einen Anker aus zuei vertikalen Säulen und einen diese verbindenden QuerträgCx- aufweist, die aus massivem Eisen bestehen, daß die Säulen von an Gleichstrom anschließbaren Spulen umgeben sind, daß das Heizlineal im Bereich dieses ersten Vorrichtungsteils angeordnet und von mindestens einer thermisch und elektrisch uirksamen Isolierschicht und einem Kühlblock gegen die Säulen und den Querträger abgeschottet ist, und daß das zweite Vorrichtungsteil von einem etu/a U-förmigen Joch aus massivem Eisen und dem darin angeordneten Widerlager gebildet ist*This object can be achieved in accordance with the invention in a device of the type in question in that the device has as a first part at least one armature made of vertical columns and a crossbeam connecting them, which are made of solid iron, that the columns are surrounded by coils that can be connected to direct current, that the heating ruler is arranged in the area of this first device part and is sealed off from the columns and the crossbeam by at least one thermally and electrically effective insulating layer and a cooling block, and that the second device part is formed by a U-shaped yoke made of solid iron and the abutment arranged therein.

Die Losung dieser Aufgabe ist jedoch dadurch möglich, daß die Vorrichtung beidseits der zu bildenden Naht jeweils einen Anker aus zuei vertikalen Säulen und einen diese verbindenden Längsträger aus massivem Eisen aufweist, daß die Längsträger oder die Säulen von an Gleichstrom anschließbaren Spulen umgeben sind, daß das Heizlineal im Bereich dieses ersten VorrichtungsteilsHowever, the solution to this problem is possible in that the device has an anchor made of two vertical columns on both sides of the seam to be formed and a longitudinal beam made of solid iron connecting them, that the longitudinal beams or the columns are surrounded by coils that can be connected to direct current, that the heating ruler in the area of this first part of the device

angeordnet Und durch eine thermische Und elektrische Isolierung Und gegebehenfalls einen Kühibiöck gegenüber den durch eitle Quertraverse verbundenen Säulen abgeschottet ist, Und daß das zweite Vorfichtungsteil von einem etua U-förmigen Joch aus massivem Eisän, dessen freie U-Schenkel mit den Unterseiten der Säulen korrespondieren, gebildet wird, und daQ dazwischen das Widerlager angeordnet ist«arranged and is separated from the columns connected by a thermal and electrical insulation and, if necessary, a cooling block, and that the second prefabricated part is formed by a U-shaped yoke made of solid iron, the free U-legs of which correspond to the undersides of the columns, and that the abutment is arranged between them.

Vorzugsweise kann dabei der Kühlbiock yon einer Luft- oder Flüssigkeitskühlung beaufschlagbar sein*Preferably, the cooling block can be supplied with air or liquid cooling *

Bei einer Vorrichtung der zueitgenannten Art uird eine besonders schmale Bauweise dadurch erreicht, daß die Längsträger jeweils an der Innenseite der Säulen angeordnet sind.In a device of the type mentioned above, a particularly narrow design is achieved by arranging the longitudinal supports on the inside of the columns.

Eine besonders leichte Austauschbarkeit der Spulen wird in weiterer Ausgestaltung der Erfindung dadurch erreicht, daß die Quer- bzw. Längsträger jeweils lösbar mit den Säulen verbunden sind.A particularly easy exchangeability of the coils is achieved in a further embodiment of the invention by the fact that the cross and longitudinal supports are each detachably connected to the columns.

Ein Lufteinschluß in der Naht ( VulkanisatiDnsfehier ) kann vorteilhaft dadurch verhindert werden, daß das Uiderlager im Bereich seiner Längsmittelebene gegenüber seinen seitlichen Randbereichen erhöht, und zwar vorzugsweise ballig ausgebildet ist.An air inclusion in the seam (vulcanization defect) can be advantageously prevented by raising the bearing in the area of its longitudinal center plane compared to its lateral edge areas, and preferably by making it crowned.

Durch beidseitige Anordnung eines Uiderlagers kann eine schüsseiartige Nahtverformung, die bei einseitigem Uiderlager auftreten kann, weitgehend vermieden werden.By arranging a gusset bearing on both sides, a shot-egg-like seam deformation, which can occur with a gusset bearing on one side, can be largely avoided.
