A short dictionary entry describing the wadding sizer, a machine that applies a coating of size to the surface of a cotton bat. It explains the parts: an upper reticulated metallic apron that presses the sized bat so the fibers adhere, a blast-pipe that detaches the bat from the apron, and a pin-pointed rotary cylinder that receives size from a rotary brush and sprinkles it on the bat. A line drawing (Fig. 7000) illustrates the machine.
