Description

8. The method according to any one of the preceding claims, characterized in that the movement the knife takes place by means of a mechanical device.

9. The method according to any one of the preceding claims, characterized in that the Contact points of the knife ornaments (such as rings, spirals, buttons and the like) attached that are pressed into the glass.

water, vases, bowls and the like., with any external shape, in which the glass gob by means of a glass blow pipe is introduced into the blow mold and blown on.

The aim of the invention is to produce such hollow glass bodies, the cavity of which is formed by an or several partition walls running approximately in the blowing direction into several equally large or different partition walls large chambers that are in communication with each other, or be separate from each other be able.

For this purpose, the invention proposes that the liquid glass gob first inflated a little and then before being introduced into the blow mold by means of one or more, single or multi-legged Knife up to the mutual contact of those opposite the contact points of the knife or knives Inner surface areas is compressed.

In the following the invention is described under ßezug-

Represent stages of the method according to the invention.

Fig. 1 to 3 show the glass gob in various NEN stages of inflation;

As Fig. 4 shows the inflated glass gob and two knives approaching him but not yet touching him;

Fig. 5 shows the compressed by the two knives until it touches its inner surface Glass posts;

F i g. 6 shows the glass gob located in the blow mold and blown apart in it;

Fig. 7 shows the hollow glass body removed from the blow mold with still uncut Edge;

8 shows the finished hollow glass body in a partially sectioned view and in a plan view;

Fig. 9 shows a during the implementation of the method used, single-leg knife in three cracks

The invention relates to a method for the production of mouth-blown hollow glass bodies, such as glasses;

Fig. 10 shows a two-legged knife used in carrying out the method in three cracks;
11 to 17 show various embodiments of the finished hollow glass body in a partially sectioned view and in a top view.

After the glass gob 1, which has a temperature of approximately 800.degree. C., has been inflated according to a form of implementation of the

5 "inventive method of two opposite Each side is approximated by a knife 2, as shown in FIG. 4. Then the two opposing knives are moved against each other until the glass gob is compressed so that

that the points of its inner surface, which are opposite the contact points of the knife, are under pressure touch. See FIG. 5. By this squeezing you will connect the one on top of the other Place the inner surface of the glass gob.

The glass gob is now introduced into the blow mold 3 and blown apart in it. Included The point of contact of the inner surface of the glass gob pulls itself out, forming an approximately in the blowing direction extending partition 4 apart, the

the cavity of the glass gob is divided into two chambers S and 6. According to FIG. 6 are these chambers unequal and they are connected to one another at the top, since the separating

Claims (7)

Patent claims: J, Process for the production of hand-blown hollow glass bodies, such as glasses, vases, bowls and the like, with any external shape, in which the glass gob by means of a blower whistle is introduced into the blow mold and blown on, characterized in that for the production of hollow glass bodies with one or more, approximately in the blowing direction Partitions of the liquid glass gob initially inflated a little and then in front the introduction into the injection mold by means of one or more single- or multi-legged knives up to the mutual contact of those opposite the contact points of the knife or knives Inner surface areas is compressed. 2.
