Description

Das Patent 878 105 betrifft eine Vorrichtung zum Herstellen von nahtlosen Hohlkörpern aus Kunststoffen, bei der der Kunststoff aus einer von einem Gehäuse und einem gegenüber diesem Gehäuse beweglichen Ventilstempel gebildeten ringf&migen Oeffnung aus/gepreßt und zu einem Hozhlkörper aufgeblasen wird, und weiche dadurch gekennzeichnet ist, daß sich Gehäuse und Ventilstempel in entgegengesetzter Richtung erstrecken. The 878,105 patent relates to an apparatus for making seamless Hollow bodies made of plastics, in which the plastic consists of a housing and an annular valve plunger that is movable with respect to this housing The opening is pressed out and inflated into a wooden body, and thereby soft is characterized in that the housing and valve stem in opposite directions extend.

Bei diesem Verfahren ist der herzustellende Hohlkörper während des Herstellungsprozesses an beiden Enden festgehalten. Das hat unter anderem den Vorteil, daß der Hohlkörper während des Herstellungsganges nicht nach der Seite »ausweichen« und außerdem während des Blasens zusätzlich in Längsrichtung gereckt werden kann. In this process, the hollow body to be produced is during the Manufacturing process held at both ends. This has the advantage, among other things, that the hollow body does not "give way" to the side during the production process and can also be stretched in the longitudinal direction during the blowing.

Bevor der Kunststoff aus dem Gehäuse ausgepreßt und zu einem Hohlkörper aufgeblasen werden kann, muß er in das Gehäuse eingefüllt werden. Im Hauptpatent sind verschiedene Möglichkeiten erwähnt, das Gehäuse mit Kunststoff zu füllen, so beispielsweise die, daß man das Gehäuse außerhalb der eigentlichen Blaseeinrichtung mit Kunststoff füllt und anschließend patronenartig in diese einsetzt. Before the plastic is pressed out of the housing and into a hollow body can be inflated, it must be filled into the housing. In the main patent various ways of filling the housing with plastic are mentioned, see above for example the fact that the housing is outside the actual bladder device fills with plastic and then inserts it into it like a cartridge.

Es wurde nun gefunden, daß sich ein technischer Fortschritt ergibt, wenn, wie die Abb. I3 zeigt, das Gehäuse 14 durch eine in dem Ventilstempel 5 angebrachte Bohrung mit Kunststoff 3 gefüllt wird, wobei die Bohrung am gehäuseseitigen Ende des Ventilstempels 5 einen ventilartigen Verschluß 2I trägt. Dadurch läßt sich erreichen, daß das Gehäuse I4 in der Blasevorrichtung verbleiben kann, was in manchen Fällen Vorteile bietet. It has now been found that there is a technical advance, if, as Fig. I3 shows, the housing 14 is mounted in the valve stem 5 by a device Bore is filled with plastic 3, the bore at the end of the housing of the valve stem 5 carries a valve-like closure 2I. In this way it can be achieved that the housing I4 can remain in the blower, which in some cases Offers advantages.
