Drive and holding device for spinning chambers ringless

Fine spinning machines

The present invention relates to a drive and holding device for spinning chambers ringless fine spinning machines »which for continuous ringless fine spinning of Textile fibers are driven by rolling.

Known spinning chambers are stored in special high-speed bearings, which on the one hand are expensive and on the other hand make high demands on maintenance through lubrication, their operation being noisy and the service life disproportionate due to their overheating during operation short is *

The invention avoids these disadvantages and creates
