Brae AG ₈ Breitenbach (SC ₃ Switzerland) Mündungseinaatss for tubes

Bs are already mouth inserts i »one essentially filled with a main paste, but in the mouth area a tube containing aggregate paste known "which cause that the aggregate paste appears as a strip in the main paste when it is pressed out. Sin such a muzzle insert is formed as a tube, the length of which corresponds to the depth of the surcharge and which is provided with side openings for the supplementary paste to pass through. When squeezing the tubs are now the main raste long through the tube

The part of the previously known execution foraien should » it is more likely that the origin of the mouth consists in the fact that its division is very difficult because of the radial openings. Venn this Openings n: Must be exactly the prescribed size "

When the two pastes have different colors, the deficiency can also be seen immediately. This disadvantage is eliminated mxa bit using the present invention. This insert is characterized in that the tube forming it has two sections of different diameters and one of these two

The Sinaatz called Ganso · old 1 sits in the mouth 2a of the tube 2. It is formed as a tube * the length of which corresponds to the depth of the additive paste 3 with which the tube in the mouth area is filled Hauptpaete k ansobliesst »Preferably these two pastes do not differ only in their composition but also in their · coloring ·» The tube 1 has a section 5 and a section 6, of which the first «we» «*» * 1 * de * ¹ ** »· 4 * β is * and iron has a larger diameter than this.

When the tube is squeezed out, the main paste is pressed through section 6 of the tube, while the additive enters through the openings 8 so that it forms the desired strips in the main paste.

As can be seen from the drawing, the section 6 is provided with bearing ribs 6a on its outside, which on the one hand contribute somewhat to the rigidity of the pipe and on the other hand
