Abstract
A spinning preparation machine includes a drafting device for drafting at least one fiber sliver. The machine includes a microwave sliver thickness sensor through which the fiber sliver is guided, the sensor disposed at the inlet or outlet, or both, of the drafting device and includes at least one cavity resonator defined by a resonator wall. A device or system is incorporated with the sensor for minimizing temperature-conditioned deformations of the resonator during measurement of sliver thickness.

1-24. (canceled)
A spinning preparation machine with a drafting device for drafting at least one fiber sliver, comprising:
- a microwave sliver thickness sensor through which the fiber sliver is guided, said sensor disposed at at least one of an inlet or an outlet of said drafting device, said microwave sensor comprising at least one cavity resonator defined by a resonator wall;
- and
- means for minimizing temperature-conditioned deformations of said resonator during measurement of sliver thickness.
A cavity resonator for use in a microwave sensor of a textile spinning preparation machine, said resonator comprising resonator walls wherein at least one of said walls is formed of a material having a low coefficient of thermal expansion at operating temperatures of the spinning preparation machine.
