Abstract

The application relates to a device for producing connecting seams between overlapping parts made of elastomeric or thermoplastic material, in particular in the case of roofing sheets or sealing sheets, the parts to be joined being heated in the region of the seam to be produced and being clamped between two device parts joined preferably not mechanically to one another, and a heating bar being provided in the region of one of the device parts and an abutment in the region of the other part. To achieve, in this arrangement, a high pressing force with high operational reliability in a simple manner, according to the invention measures are proposed for generating the pressing force by means of magnetic fields and for dissipating or insulating the heat produced during the operation of the device.

Description

Die Erfindung betrifft eine Vorrichtung zum Her­ stellen von Verbindungsnähten zwischen sich über­ lappenden Teilen aus elastomerem oder thermoplasti­ schem 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 einge­ spannt werden, und im Bereich eines der Vorrich­ tungsteile ein Heizlineal und im Bereich des anderen Teils ein Widerlager vorgesehen ist.The invention relates to a device for the manufacture put connecting seams between them lapping parts made of elastomer or thermoplastic cal material, especially in roof or Sealing membranes, the parts to be connected heated in the area of the seam to be produced and preferably not between two mechanically connected parts of the device be stretched, and in the area of one of the Vorrich parts a heating ruler and in the area of the other part an abutment is provided.

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 Druck aufzubringen.Such a device is already the DE-OS 34 27 215 as known. However, it is technically complex over there provided vacuum chambers for manufacturing flawless seams require high pressure to apply.

Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, eine solche Vorrichtung derart weiter­ zuentwickeln, daß sie bei einfachem Aufbau und großer Zuverlässigkeit im Betrieb die Herstellung einwandfreier Nähte sicherstellt.The object of the present invention was therefore based on such a device further develop that with a simple structure and manufacturing reliability ensures perfect seams.

Diese Aufgabe kann bei einer gattungsgemäßen Vorrichtung erfindungsgemäß dadurch gelöst werden, daß die Vorrichtung als erstes Teil mindestens einen Anker aus zwei vertikalen Säulen und einen diese verbindenden Querträger aufweist, die aus massivem Eisen bestehen, daß die Säulen von an Gleichstrom anschließbaren Spulen umgeben sind, daß das Heizlineal im Bereich dieses ersten Vor­ richtungsteils angeordnet und von mindestens einer thermisch und elektrisch wirksamen Isolierschicht und einem Kühlblock gegen die Säulen und den Querträger abgeschottet ist, und daß das zweite Vorrichtungsteil von einem etwa U-förmigen Joch aus massivem Eisen und dem darin angeordneten Widerlager gebildet ist.This task can be done with a generic Device can be solved according to the invention that the device as the first part at least an anchor consisting of two vertical columns and one has these connecting crossbeams made of solid iron exist that the pillars of at DC coils are surrounded, that the heating ruler in the area of this first pre arranged in a directional direction and by at least one thermally and electrically effective insulating layer and a cooling block against the columns and the Cross member is sealed off, and that the second Device part of an approximately U-shaped yoke made of solid iron and what is arranged in it Abutment is formed.

Die Lösung dieser Aufgabe ist jedoch dadurch möglich, daß die Vorrichtung beidseits der zu bildenden Naht jeweils einen Anker aus zwei 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 Heiz­ lineal im Bereich dieses ersten Vorrichtungsteils angeordnet und durch eine thermische und elek­ trische Isolierung und gegebenenfalls einen Kühlblock gegenüber den durch eine Quertraverse verbundenen Säulen abgeschottet ist, und daß das zweite Vorrichtungsteil von einem etwa U-förmigen Joch aus massivem Eisen, dessen freie U-Schenkel mit den Unterseiten der Säulen korres­ pondieren, gebildet wird, und daß dazwischen das Widerlager angeordnet ist.However, this solves this problem possible that the device on both sides of the forming an anchor from two vertical columns and a connecting them Solid iron longitudinal member that the Side members or the pillars of direct current connectable coils are surrounded that the heating ruler in the area of this first part of the device  arranged and by a thermal and elek trical isolation and optionally one Cooling block compared to that with a crossbar connected pillars is sealed off, and that the second part of the device from about U-shaped yoke made of solid iron, its free U-leg corres with the undersides of the columns pond, is formed, and that in between that Abutment is arranged.

Vorzugsweise kann dabei der Kühlblock von einer Luft- oder Flüssigkeitskühlung beaufschlagbar sein.Preferably, the cooling block can be of one Air or liquid cooling can be applied be.

Bei einer Vorrichtung der zweitgenannten Art wird eine besonders schmale Bauweise dadurch erreicht, daß die Längsträger jeweils an der Innenseite der Säulen angeordnet sind.In a device of the second type becomes a particularly narrow construction achieved that the side members each on the Inside of the columns are arranged.

Eine besonders leichte Austauschbarkeit der Spu­ len wird in weiterer Ausgestaltung der Erfindung dadurch erreicht, daß die Quer- bzw. Längsträger jeweils lösbar mit den Säulen verbunden sind.A particularly easy interchangeability of the Spu len is in a further embodiment of the invention achieved in that the cross member or longitudinal member are detachably connected to the columns.

Ein Lufteinschluß in der Naht (Vulkanisations­ fehler) kann vorteilhaft dadurch verhindert wer­ den, daß das Widerlager im Bereich seiner Längs­ mittelebene gegenüber seinen seitlichen Randberei­ chen erhöht, und zwar vorzugsweise ballig aus­ gebildet ist.An air trap in the seam (vulcanization errors) can advantageously be prevented by this that the abutment in the area of its longitudinal middle plane opposite its lateral margins chen increased, preferably spherical is formed.

Durch beidseitige Anordnung eines Widerlagers kann eine schüsselartige Nahtverformung, die bei einseitigem Widerlager auftreten kann, weit­ gehend vermieden werden. By arranging an abutment on both sides can a bowl-like seam deformation, which at unilateral abutment can occur, far be avoided.  

Weitere vorteilhafte Ausgestaltungen der Erfin­ dung sind den weiteren Patentansprüchen zu ent­ nehmen.Further advantageous refinements of the Erfin are to be found in the further claims to take.
