Abstract

In the process I have developed, the interaction of the suction device with the fed compressed air is of great importance in the heating of retreaded motor vehicle casings. The essential factor of this process is the manner in which, after completion of the heating process, the heating water is removed from the lower part of the now finished casing. This is carried out by means of a suction device which is connected to a flexible hose. By the feeding of compressed air, the process time is reduced to 10-30 seconds. In the case of bellows (bladder) and bag heating, the process time depended on natural gradients and thus the process took up to 5 minutes longer. For the person skilled in the art, my ideas are adequately represented in the text and drawing.

Description

Verfahren für die Beheizung von KFZ-Reifen Procedure for heating vehicle tires

im Rahmen der Runderneuerung In diesem Verfahren wird das Benutzen von Schlauch oder Balg ausgeschlossen, Arbeitszeit gespart und die betriebliche Sicherheit wesentlich erhöht. in the context of retreading In this process, the use excluded from hose or bellows, saved working time and operational Significantly increased security.

Der zu erneuernde Reifen wird zwischen eine Vorrichtung (Zeichnung) gelegt, die aus einem Ober- und Unterteil besteht. Diese Platten sind so geformt, daß sie im zusammengefügten Zustand die notwendige Felgensitzabdichtung erreichen.The tire to be replaced is placed between a device (drawing) laid, which consists of an upper and a lower part. These panels are shaped to that they achieve the necessary rim seat seal in the assembled state.

Im Mittelpunkt des Oberteils ist ein Dampf- und Wasser zu lauf vorgesehen, wobei die Örtlichkeiten dem jeweiligen Heizautomaten angepaßt werden können, was auch für die Druckluftzufuhr im oberen Teil und den Wasserablauf im unteren Teil der Vorrichtung gilt. Im unteren Teil der Vorrichtung wird ein flexibles Saugrohr zum tiefsten Punkt der Decke geleitet.In the center of the upper part there is a steam and water outlet, whereby the localities can be adapted to the respective automatic heating system, what also for the compressed air supply in the upper part and the water drainage in the lower part of the device applies. In the lower part of the device there is a flexible suction tube directed to the lowest point of the ceiling.

Dieses flexible Saugrohr ist mit einem Stahlabsaugstück versehen und muß vor Abnehmen des Reifens manuell entfernt werden.This flexible suction pipe is provided with a steel suction piece and must be removed manually before removing the tire.

Funktionsbeschreibung: In die geöffnete Vorrichtung kommt die zu bearbeitende Decke.Functional description: The device to be processed is placed in the opened device Ceiling.

Der Schnorchel wird in die Decke eingelegt. The snorkel is placed in the ceiling.

Die Form wird geschlossen. The mold is closed.

Der Reifen wird durch Luftdruck in den Felgensitz gebracht. Das Aufblasen mit Dampf ist nicht ratsam, da durch das Entweichen des Dampfes im noch nicht geschlossenen Felgensitz Beschädigungen an der Decke auftreten können. The tire is brought into the rim seat by air pressure. The inflation using steam is not advisable, as the escape of steam in the not yet closed Rim seat damage to the ceiling can occur.

Mit kurzem Dampf stoß wird die Luft aus dem Reifen gedrückt. The air is forced out of the tire with a brief burst of steam.

Danach erfolgt der normale Heizvorgang mit Dampfstoß und anschließender Zuführung von Heizwasser. This is followed by the normal heating process with a burst of steam and then Supply of heating water.

Nach dem Heizvorgang wird das Heizwasser mit dem Schnorchel abgesaugt, wobei Druckluft zugeführt wird. After the heating process, the heating water is sucked off with the snorkel, whereby compressed air is supplied.

Der Schnorchel wird aus der Decke entfernt und in eine Schutzvorrichtung auf der unteren Platte gelegt. The snorkel is removed from the blanket and placed in a protective device placed on the lower plate.

Die Decke ist jetzt fertig und kann aus der geöffneten Form genommen werden. The blanket is now ready and can be removed from the opened shape will.

Vorteile: 1. Beim Heizen mit Balg war man auf das natürliche Gefälle angewiesen und hatte für das Ablaufen des Wassers 2 Minuten bei PKW und 5 Minuten bei LKW vorgesehen.Advantages: 1. When heating with bellows you were on the natural gradient instructed and had 2 minutes for the car and 5 minutes for the water to run off provided for trucks.

2. Durch das Zusammenwirken des Schnorchels mit der Druckluft wird die Kosten und Zeit verursachende Ablaufzeit auf 20 bis 30 Sekunden gesenkt. Der direkte Einfluß von Dampf und Heizwasser kann die Heizzeit verkürzen, somit wird Heizöl gespart.2. The interaction of the snorkel with the compressed air is the cost and time causing expiration time reduced to 20 to 30 seconds. Of the direct influence of steam and heating water can shorten the heating time, thus Saving heating oil.

3. Das Danebenlaufen des Balges, Ablaufverstopfung und das Auswechseln des Balges ist nicht mehr gegeben. Schwerste Arbeit und damit Zeit werden gespart.3. Missing of the bellows, drain blockage and replacement the bellows is no longer given. The hardest work and thus time are saved.

4. Das komplizierte Einziehen des Balges und die hierfür geschaffene Einziehvorrichtung fallen weg.4. The complicated retraction of the bellows and the one created for this Retraction devices are no longer necessary.

Nach diesem Verfahren habe ich bereits 800 PKW-Decken ohne Störungen und mit guten Ergebnis geheizt.After this procedure I already have 800 car blankets without interference and heated with good results.
