Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft ein Verfahren zur Herstellung von beliebig langen Gegenständen aus gepulvertem Gummiabfall, welcher mittels eines hin und her gehenden Kolbens in einer Form von entsprechendem Querschnitt gepreßt und erhitzt wird.The invention relates to a method for producing objects of any length from powdered rubber waste, which by means of a reciprocating piston in a Shape of appropriate cross-section is pressed and heated.

Die Erfindung besteht darin, daß bei jedemThe invention is that with each

Kolbenhub nur Teilmengen der Gummimasse vorgeschoben werden. Hierdurch werdenPiston stroke only partial amounts of the rubber mass are advanced. This will be

ίο homogene Gummigegenstände in beliebigen Längen erhalten.ίο homogeneous rubber objects in any Maintain lengths.

Auf der Zeichnung ist eine zur Ausführung des neuen Verfahrens dienende Vorrichtung beispielsweise in einem Längsschnitt veranschaulicht. For example, a device used to carry out the new method is shown in the drawing illustrated in a longitudinal section.

Der Kopf Ä2 des Kolbens h paßt in die Höhlung der für die Herstellung massiver Radreifen in großen Längen bestimmten Form k und ist an seinen Kanten ausgezackt, um das Entweichen der in dem gepulverten Gummiabfall enthaltenen Luft während der Zusammendrückung zu ermöglichen. Der gepulverte Gummi fällt durch einen Trichter in die Kammer h3, in welcher der Kolben h sich hin und her bewegt, so daß er bei seinem Treibhub einen Teil des Pulvers vorwärts führt und eine geringe Menge in' die Form k stößt, wo das Pulver stark zusammengedrückt und von Luft befreit wird. Hierbei wird der gesamte in der Form bereits enthaltene Gummi um ein kleines Stück vorwärts geschoben.The head Ä 2 of the piston h fits into the cavity of the shape k intended for the production of massive wheel tires in great lengths and is jagged at its edges to allow the air contained in the powdered rubber waste to escape during compression. The powdered rubber falls through a funnel into the chamber h 3 , in which the piston h moves back and forth so that on its driving stroke it leads part of the powder forward and pushes a small amount into the mold k , where the powder is strongly compressed and freed of air. In doing so, all of the rubber already contained in the mold is pushed forward a little.

Die zweiteilige Form k ist durch eine Metallwicklung k1 umgeben und mit einem Flansch £a versehen, welcher in dem Pressenkopf e durch Ringe ks und ß4 gehalten wird. Die Kammer kB enthält eine Heizvorrichtung.The two-part mold k is surrounded by a metal winding k 1 and provided with a flange £ a , which is held in the press head e by rings k s and ß 4 . The chamber k B contains a heating device.
