Abstract
A rotary chuck for winding magnetic tape aligns the winding hub in both the axial and radial directions relative to the axis of winding rotation. This allows higher winding speeds to be used and produces finished rolls of improved quality. Alignment occurs upon application of air pressure to the rotary chuck. The rotary chucks can be placed side-by-side on a single mandrel for winding multiple strands simultaneously. Winding hubs can be easily slipped on and off the rotary chucks to improve winding productivity.
