... machine system and a vertical winding machine. The chapter provides information on in-plane (polar) winders and several types of creels, namely stationary and no twist, rotating, braking, and combinations thereof. Comprehensive descriptions of mandrel designs used in filament winding are presented in text...

.... To expand a tube, a ring-shaped supply can be attached to one end of the tube, so that the current is fed into the workpiece here. The second contact should be realized at the other end of the tube, and the current should be conducted through the inner tube by a mandrel. Radial Lorentz forces result from...
