A dictionary entry on roving in cotton manufacture, defined as a slightly twisted sliver and as the process between carding and spinning. It describes how slivers from cans are doubled and drawn between rollers, then twisted, and compares Arkwright's rotating-can method, the jack-frame, and the bobbin and fly frame. It also explains how the spindle, flyer and bobbin give twist and wind the roving, and includes a diagram of a roving machine (Fig. 4433).
