Winding shaft e.g. for flexible area measured material, has aligned, helical rolled up spring along winding axle, and several spring coils which are effective for rolling up function

摘要

The shaft has an aligned, helical rolled up spring along a winding axle, and provided with a multiplicity of spring coils, which are effective for the rolling up function. The spring coils are seen in sections relative to each other and change over the length of the spring. The change of configuration is implemented on a cross-section. The changed configuration is intended by a transfer of the spring coils relative to the winding axle (W). Different sections of the effective spring coils are wound against each other. The cross-sectional change by a cross section taper ratio and or a cross section extension is implemented by the spring coils.
