Abstract

The Parent Patent described a folding membrane which is applied to the inside of a tyre under pressure during the heating operation. this has now been equipped with ducts between the inner wall of the tyre and the outside of the membrane. A fluid under pressure can be admitted through them when the folding membrane is to be extracted. The folding membrane is secured in the fixture inside the tyre. A network of fine hoses with openings can be used to introduce a pressurized fluid through a connection in the fixture to break away the folding membrane from the inner wall. This deals with the forces of stiction and overcomes the difficulties of detaching the membrane from the tyre walls.

Description

Vorrichtung zur Erzeugung eines Druckpolsters zwischen Reifen-Innenwand und Faltmembrane (Patentanmeldung P 28 o2 783.0 und P 28 15 765.5) a.) Aufgabenstellung: Die Lösung des,während des Heizvorganges des Reifens mit Druck beaufschlagten Presskörpers(Heizschlauch,Heizbalg etc.), im gegenständlichen Fall,-der Faltmembrane,- von der Innenseite des Reifens, erfordert fallweise beachtliche Loslöskräfte.-Diese Loslöskräfte sind häufig nur durch zusätzliche, technische,mechanische,zum Teil kostspielige und komplizierte Vorrichtungen zu erreichen.Device for creating a pressure cushion between the inner wall of the tire and the folding membrane (Patent application P 28 o2 783.0 and P 28 15 765.5) a.) Task: The solution of the compressed body (heated hose, bladder, etc.), which is pressurized during the heating process of the tire, in the present case - the folding membrane, - from the inside of the tire, requires considerable detachment forces in some cases. - These detachment forces are often only to be achieved by additional, technical, mechanical, sometimes expensive and complicated devices.

b.) Lösung : Eine wirksame Lösung ist Gegenstand dieser Patentanmeldung für die wirksame Loslösung der Faltmembrane durch die Erzeugung eines Druckes zwischen Faltmembrane und Reifen-Innenwand,zum Zwecke der Loslösung und Vorbringung der Membrane in deren Ruhestellung, als alleiniger,und oder <iie Verbringung in die Ruhestellung der Membrane als den Einfaltvorgang mechanisch, und oder nach dem Vakuum-Verfahren unterstützender Vorgang, bezw.unterstützendes Verfahren.b.) Solution: An effective solution is the subject of this patent application for the effective detachment of the folding membrane by generating a pressure between Folded membrane and inner wall of the tire, for the purpose of detaching and bringing the membrane forward in their rest position, as the only one, and or <iie movement into the rest position the membrane as the folding process mechanically, and / or according to the vacuum process supporting process or supporting process.

1.) Die Halte-und oder Befestigungsvorrichtung (H) der Faltmembrane (F) verfügt über Vorrichtungen zur Befestigung und gewollten und kontrollierten Druckfüllung der Leitung,bezw.Leitungen (L) . Fig. 1 2.) Wird dieser oder diesen Leitungen ein gewollter Druck zugeführt,so strömt dieser aus der Offntlns (A) aus,und drückt,-unter Bildung des Raumes(B) die Faltmembrane,-unter Lösung von der Reifen-Innenwand in Richtung (C),der Ruhestellung der Faltmembrane.Fig. 2 und Fig. 3 3.) Der Füllvorgang zur Bildung des Raumes (B) wird erst dann durchgeführt,wenn der zur Heizung des Reifens notwendige Innendruck der Faltmembrane,ganz, oder weitgehendst,abgelassen wurde.-4.) Dieser Abdruckvorgang wird zur Unterstützung des gewollten Einfaltvorganges der Faltmembrane in deren Ruhestellung,in Verbindung mit dem Vacuum -Einzugverfahren ge-und oder benutzt.-Der beschriebene Abdruckvorgang kann aber auch für sich allein so ablaufen und gesteuert werden,dass er allein,-bei entsprechende der Gestaltung der Faltmembran-Oberfläche die Faltmembrane in die gewolte Ruhestellung bringt,bezw.drückt.- 1.) The holding and / or fastening device (H) of the folding membrane (F) has devices for fastening and deliberate and controlled Pressure filling of the line or lines (L). Fig. 1 2.) Will this or these If the lines are supplied with a desired pressure, this flows out of the opening (A), and presses the folding membrane, forming space (B), releasing it from the inner wall of the tire in direction (C), the rest position of the folding membrane. 2 and Fig. 3 3.) The filling process for the formation of the room (B) is only carried out when the one for heating the Tire's necessary internal pressure of the folding membrane, completely or largely, drained was.-4.) This printing process is used to support the wanted Folding the folding membrane in its rest position, in connection with the vacuum - Collection process used and or used. - The printing process described can, however also run and be controlled for himself in such a way that he alone, -with appropriate the design of the folded membrane surface, the folded membrane in the convex rest position brings, or presses.

Claims

Claims: (1) folding membrane, as described above, and thereby marked that on their attachment (H) devices for attachment and pressure filling of the lines (L) exist. Fig. 4 2) folding membrane as described above and characterized in that deise lines between the membrane surface and guide the tire inner wall or be guided.

3) folding membrane according to claim 2) and characterized in that when the lines (L) are pressurized, this pressure emerges from the openings (A), and forms one or more desired spaces (B). Fig. 5 4.) Folding diaphragm, after a or more of the preceding claims, characterized in that when pressure is applied the lines (L) with air, water, or another suitable pressure medium, the The membrane is detached from the inside so that this solution is based on both its area, Size and strength and or direction can be controlled.- Fig. 6 5.) Folded membrane, according to one or more of the preceding claims, characterized in that the membrane surface can be provided with one or more filling spaces (D). That these filling spaces (D) are separated from one another, and or may be connected to one another, so that with the appropriate dosage of the applied pressure, a desired, and / or controlled one Movement of the folding membrane in the direction of its rest position takes place. Fig. 7 6.) As a result marked folding membrane according to one or more of the preceding claims that the limitation or limitations of the filling spaces (D) made of elastic and or inelastic, and or other material. And that they consist of hoses, elastic tubes that are filled or are filled with a pressure medium, and on the membrane surface are applied, and or parts of the membrane are. Fig, 8 7.) Folded membrane after one or more of the preceding claims, characterized in that the, under Formation of the space (B) under or ollne use of the filling spaces (D) wanted and created Movement of the membrane in the direction of its rest position alone, and or in conjunction with one created in the space enclosed by the folding membrane Vacuum, leads to the membrane being folded in when it is in its rest position.

8.) Ealtmembrane, according to one or more of the preceding claims, characterized characterized in that the lines (L) on the membrane surface, and / or the inner surface of the membrane, applied and or attached.
