Roller with an inner bore or cylinder made of plastic, in particular a pore-open, elastic plastic foam, like polyurethane foam

Rollers with inner bores or cylinders made of synthetic foams, v / ie pore-open polyurethane acids, are available in different technical areas for 'application, for example as transport or application rollers in copiers or as a paint application roller with hand rollers to apply paint.

The innovation has set itself the task, foam rollers or foam cylinders to create what special Have properties which were previously not achievable and are of great importance for many purposes Meaning are.

“For example, such foam rollers as a paint application roller For paints containing solvents, the foam swells when exposed to the solvent during use and there is a risk that the cylinder will easily become detached from its holder. Similar

Phenomena occur when such Schaunis fabric rollers are used for other application purposes, which solvents that act on the foam in question.

To solve the task on which it is based, the innovation consists of a roller with an inner bore or cylinder made of synthetic resin display material, in particular pore-open elastic synthetic foam, such as polyurethane foams or the like, which are used in their physical training has the peculiarity that the wall of the inner bore is designed as a melt skin. The enamel skin can be produced by a firing or melting process. In all cases it is appropriate that the wall of the inner bore is melted and smoothed. The production of the bore and enamel skin is advantageously carried out with a tool according to DT-Gm 7527416.

Further advantageous details of the innovation can be seen from the drawing, in which, for example, a synthetic foam roller is illustrated according to the innovation. In the drawing, a foam roller according to the innovation is for example illustrated.

The roller 21 is provided in its inner bore 22 with a melt skin 23, which, as mentioned, for a wide variety of stresses and uses of such foam rollers or cylinders is essential and beneficial.

Now through the merger it is achieved that the / has become stable Inner skin in the inner bore of the swelling tendency of the foam TTiaxerial in connection with solvent-based materials counteracts and is reduced to almost zero. Also for different Such an enamel skin has proven to be useful for such stresses.

The assembly of the foam roller for its purpose, at

for example as a paint application roller, can thus be ended by pressing in a corresponding guide bush. the Previous adhesive processes can be completely omitted and, moreover, are for various types of plastic, such as polyethylene or the like, no adhesive connections at all possible, since the fabric itself is resistant to chemicals.

All shown in the drawing and in the description The technical details explained are important for the innovation.
