Description

Verfahren zur Herstellung von naht- un d endlosen Hohlreifen aus breliger, später erhärtender Iffasse mittels verlorener Form. Die Erfindung bezieht sich auf ein verbessertes Verfahren zur Herstellung von naht-und endlosen Hohlreifen aus breiiger, später erhärtender Masse mittels verlorener' Form gemäß Patent 316122 und betrifft eine Ausführungsform, bei der in dem in die Masse eingelegten Luftschlauch neben dem Einlaßventil *noch ein Auslaßventil vorgesehen ist, um nach dem Formen der Masse durch Hindurchleiten von warmer Luft eine schnelle Trocknung und Erhärtung des Hohlreifens zu ermöglichen.A process for producing seamless un d endless hollow tires breliger, later hardening Iffasse by means of lost form. The invention relates to an improved method for the production of seamless and endless hollow tires from pulpy, later hardening mass by means of lost 'form according to patent 316122 and relates to an embodiment in which in the air hose inserted into the mass, in addition to the inlet valve *, an outlet valve is provided in order to allow rapid drying and hardening of the hollow tire after the molding of the mass by passing warm air through it.

. In der Zeichnung ist in einem Beispiel eine Innenansicht einer Preßform zur Durchführung des Verfahrens veranschaulicht. . In the drawing, an example of an interior view of a compression mold for carrying out the method is illustrated.

Die gezeigte untere Hälfte a der Preßform ist mit der breiigen Formmasse b gefüllt, in deren Mitte der leere Luftschlauch c aus Gummi oder anderem nachgiebigen Stoff so aufgelegt ist, daß das Einlaßventil d und das Auslaßventil e durch in der Innenwandung der Ringförm a vorgesehene Öffnungen in den freien Innenraum der Ringforin vorragen. Während des Formens wird das Rückschlagventil d an einem Druckluftbehälter oder -erzeuger angeschlossen und das Ventil e geschlossen gehalten. - Nach vollendetem Formen öffnet man das Ventil o entsprechend , und läßt durch Ventil d warme Luft mit oder ohne Druck einströmen, um ein schnelles Trocknen und Erhärten der Masse des Hohlreifens zu erzielen.The shown lower half a of the mold is filled with the pulpy molding compound b , in the middle of which the empty air hose c made of rubber or other flexible material is placed so that the inlet valve d and the outlet valve e through openings provided in the inner wall of the annular shape a protrude the free interior of the ring shape. During molding, the check valve d is connected to a compressed air tank or generator and the valve e is kept closed. - After the molding has been completed, the valve o is opened accordingly , and warm air is allowed to flow in through valve d, with or without pressure, in order to achieve rapid drying and hardening of the mass of the hollow tire.
