In the winding device for the winding of yarns, the bobbin tubes are clamped on chucks. Severing knives are arranged in front of or behind the chucks on the bobbin-winding mandrel. Furthermore, there are yarn-catching devices which catch and clamp the yarn to be wound, for the purpose of piecing the yarn. The yarn-catching device has axially moveable catching rings which are actuated simultaneousl...

Long-term lubrication of highly loaded lubricating areas or surfaces, such as in very high speed medical and/or dental equipment, is obtained by applying a synthetic film, for example composed of poly(fluoroacrylic acid methyl ester) onto the sliding/moving surfaces, along with a polar oil having high lubricity. Anti-microbial agents can be added to the synthetic film. A pre-coat of molybdenum sul...
