te is pressed and this results in uneven material thickness. In addition to the risk of uneven material thicknesses arising, the machining of the hemispherical shell chosen as an example requires unnecessarily frequent rolling of the surface and thus a large expenditure of time. The same drawbacks exist with the roll body spirally wound from thick steel wire. This is because of Flexibility is not possible due to the thick wire thickness. If the wire thickness is chosen to be thinner, the winding layers must inevitably be tighter are laid, which in turn leads to the fact that the glass fiber tips when rolling get caught between the wrapping layers and be torn out of the sprayed-on polyester resin.

The invention is based on the object that, when rolling glass fiber chips in polyester synthetic resin, uniform material thicknesses can be achieved and the total width of the ventilation roller is used to save considerable time.

This object is achieved according to the invention in that a washer cut roller body is mounted rollable on a flexible axis, which is located on a handle. To a better one To achieve bending of the roller body, the individual roller disks are given a rhombic cross-section. The flexible axis can be attached so that it forms the tendon in a fork-shaped handle, or that it forms a with the handle T-shape represents.

The advantages achieved by the invention are, in particular, that companies that process glass fiber reinforced polyester resin are able to achieve uniform material thicknesses for workpieces with bulges and depressions without difficulty and in a simple manner in order to save time.
