Device for trimming brushes with against the outer field detached ßlittelfeld

So far, the manufacture of brushes with two has been different long filling materialsj cL ho brushes ^ like z ° Β »scrubbing ;, Barrel brushes and the like, whose purpose is a separate one ilflittelfeld is generally very cumbersome

With these types of brushes, the middle part had to be stuffed first with short bristles, and then *, in a repeated pass _9, the "beard" with longer filling material, »So there were a total of four processing steps, namely two tamping and two fasting steps - required for completion

The innovation aims at providing a ,, device which allows ^ brush with remote middle simple and quick to manufacture. This object is gelöstj by a combination of two superposed prongs shaving heads, which are adapted to the desired sectional shape of midfield and AuSenfeld and of which the one was used to trim the outer forest and the other to trim the inner field at the same time

When using the control device according to the can Brush can be stuffed with filling material in one go? whose bristles are of the same length throughout = The brush prepared in this way can then be used in a single further operation by means of the device after the masonry has been laid ierden finished trimmed «Here the one cuts

Zacksnscherkopf off the lower level IMttelfeid _{? o} iöerden while the trimmed outer ^ projecting bristles by means of the other Zackanscherkopfes The previously required four operations are therefore to ztiaei operations reduced mas in the production of brushes of the type considered a performance improvement of up to 50% result hato

The new cutting tool is universally applicable = Es. can »be designed according to individual wishes ,, for straight ^ oval or also combined cut (middle field straight ₉ outer field oval or vice versa)»

In an advantageous embodiment of the masonry, the two superimposed prong shear heads can be driven by a common drive element _{or the like}

The innovation is based on one thing
