With the previously known roller brushes that are used in the leather processing industry, the bristle support bodies are designed as elongated segments or half-shells made of wood. the Manufacture of these bristle carriers and their fastening on the brush shaft by means of screw bolts is cumbersome, time-consuming and uneconomical compared to current working methods. Furthermore, the roller brushes equipped with wooden parts tense and warp under the Influence of humidity and temperature fluctuations sometimes to such an extent that the The roller brush runs out of balance in the machine, which generates critical vibrations, which can cause accidents. Most of the time, the roller brushes warp during overseas transports.

With the slightest deflection of the brush shaft, dangerous vibrations and hitting occur, so that the brush pattern on the workpiece surface is disadvantageously wavy. The processed leather is in his Goodness diminished in value.

Repairs to such roller brushes are due to the need to dismantle the wooden ones Segments or half-shells cumbersome. In most cases, the accuracy of the bristle carriers is inadequate, which must be laboriously corrected by reworking.

The object of the invention overcomes these disadvantages. It concerns a roller brush - the in Lengths of up to six meters are required by the leather industry - with the brush roller in individual round brushes is broken down, the bristle carriers are plastic rings, which - laterally flush interlocking - are pushed onto the brush shaft and thus wedged.

According to the invention, a separate profile tube with molded guide grooves is now pushed onto the brush shaft and wedged with it by strips. The individual round brushes are then lined up on the profile tube in a manner known per se, so wedged and held at the free end on the profile tube by means of adjusting rings in the seat.

The roller brush constructed in this way can be delivered to the respective customer in individual pieces because assembly and disassembly is easy if the cover needs to be replaced. Farther the balanced concentricity of the individual sections is guaranteed after assembly. the Rollers run at a speed of 400 to 800 rpm, so that when required Brush lengths and mass weights in any case roller brush

the vibration and twisting of the brush roller is avoided. The critical number of revolutions is around 500 rpm.

The still known ring brushes are lined up directly on a rotating shaft, so that the working pressure is transmitted directly and this creates unpleasant deflections.

The subject of the invention is to be able to cope with these high pressure loads when working with leather have been developed in such a way that the amount to be transmitted from the brush to its shaft Working pressure not directly, but indirectly via a specially designed profile tube is transmitted. The pipe has the task and effect of the rotary pressure that occurs, in particular those that occur only piece by piece along the length of the axis, evenly over the length of the roller to be transferred to the shaft and to be able to withstand a high bending moment. To this The roller brush rotating at high speed, whose shaft does not cover short distances, is but is evenly distributed over the entire length, loaded.

The success is that there is no deflection and that the machine runs vibration-free and, As required, an optically shadow-free leather surface is created when the workpieces are brushed.

In the drawing, the subject matter of the invention is shown in an exemplary embodiment. It shows

F i g. 1 the roller brush, partly in longitudinal section and partly in view,

F i g. 2 the brush in cross section and

3 and 4 a bristle support body of a Single round brush in view and cross-section.

On the brush shaft 1 is the profile tube 2, on which the length of two opposite one another

Guide grooves 6 are formed, pushed on and wedged by strips 3 with it. On the one held in the seat Profile tube 2, the bristle support bodies of the individual round brushes 4 are lined up next to one another and held at the free ends of adjusting rings 5.

The bristle support bodies are designed as an annular body made of plastic, e.g. B. Bakelite, made into the, the Bundles of bristles 10 are punched. On the opposite sides 8, they have recesses 7 that match the guide grooves 6. From factory Material and weight savings can be made inside the bristle support bodies, so that when mounted Roller brush between profile tube 2 and individual round brushes 4, a gap 9 remains.

So that the individual brushes 4 intermesh flush and a uniform brush roller body release, the annular bristle support bodies are on the front side surfaces with a recess 11 or a recess 12 is provided.

Claims (1)

Claim: Roller brush with brush roller divided into individual round brushes, in which the individual round brushes - laterally flush with each other - pushed onto the brush shaft and thus are wedged, characterized in that the brush shaft (1) has its own profile tube (2) with molded guide grooves (6) pushed on and wedged with it by strips (3) and that the individual round brushes (4) are lined up on the profile tube (2) in a manner known per se and are wedged with it.
